How long will the child's urine test be performed? How much is a general urine test. How much urine is made
Urine analysis is the process of investigating the physico-chemical parameters - salts, blood cells, proteins, microflora and the amounts dissolved therein. All of these indicators have a high value, especially in diagnosing the general condition of the body and the urinary system.
Chemical composition and properties of urine
Currently, medicine has identified about 150 chemical compounds that control the condition of the urinary system and the organism as a whole. For example, some urea is a completely natural and normal urine component, but there are other components that should be absent or inadequate in healthy human urine (Bens-Jones protein) - protein, red blood cells, white blood cells, glucose. The increase in the number of these components indicates pathological processes that lead to the need for a detailed urine analysis for violations.
When urine is found, drug tests are also performed. Depending on the condition and the results of the initial test, it is likely that the stomach, liver, and so on. Analysis of other tissues, including their contents, may be necessary. The liver is the main solid tissue for use in postoperative toxicology, because it is where the body metabolizes most drugs and toxicants. Many drugs are concentrated in the liver and can be found even if there is no level in the blood. In this latter case, the interpretation of the results is difficult.
The list of indicators to be studied in the clinical analysis of urine is very broad - the main part of this list:
Colors, transparency and odor;
Specific density (weight);
Acid reaction (pH);
Protein compounds;
glucose;
ketones;
Bile acid;
Bilirubin;
The ürobil;
Blood cells and pigments - hemoglobin, porphyrin, hemosiderin;
Myoglobin;
melanin;
The indikan;
Nitrite compounds.
The choice of urine parameters examined depends on the type of pathology recommended. For example, in the case of endocrine disorders, it is important to determine the presence and amount of ketone and glucose in the urine, and for nephrological problems it is necessary to determine blood protein and pigments. Usually, a urine screening test is performed to exclude or acknowledge violations in both hereditary and acquired metabolic processes. As a rule, such tests are used in the diagnosis of infants.
It can be a useful screening fluid for various drugs. Vitreous is usually analyzed for the concentration of alcohol in the blood. This is of particular importance in motor vehicle injuries, workplace accidents, suicides and murders. The alcohol concentration in alcohol is slightly higher than the amount in the blood, unless it deteriorates.
Other less used samples for postmortem toxicology
Interpreting other toxicological data in vitreous humor is somewhat more complex. Stomach contents Because drugs and poisons often enter the stomach, stomach contents can provide important research guidance. In the event of a potential overdose or acute poisoning, high concentrations of the drug or toxins may be detected, depending on the time elapsed between swallowing and death. In many cases of acute intoxication, insoluble capsules or tablets may be detected, which allows a relatively simple identification of drugs or poisons.
Daily diuresis determination method
Daily diuresis is not a fixed value, but varies depending on the time of day and the composition of the diet. In addition, there is a direct dependence on age, for example, a child has a baby, diuresis is a bit more natural than normal, which is normal and natural.
Use test tubes with measured labels for identification of quantitative indicators. The greatest amount of secreted urine is observed during the day - between two and six hours and the smallest - at night. It is accepted as the ratio of normal diuresis day to 3 - 4/1.
The total amount of drug or poison in the stomach is more important than its concentration, because it has not yet been processed by the body. Bone and marrow - bone, especially bone marrow, can be used to test if necessary, but the presence and condition of bones within the skeleton may limit their usefulness. There is no evidence that bones in one part of the body are better than others for toxicological tests. However, it is always easier to remove samples from larger bones.
The interpretation of these results is often difficult to assist in the investigation of death, because the time to release these toxins to the bones cannot be adequately determined. Hair and nails - hair samples usually taken from the back of the head can be used to test the effects of heavy metals and drugs for several weeks and months. The hair is mainly used for drug tests such as amphetamines, cocaine, marijuana and heroin, and more recently, tests have been conducted to determine if they have died too much in the few months before death.
Zimnitsky work
This method of urine analysis allows you to determine the degree to which the kidneys are able to regulate the process of urinary excretion and concentration, and in particular assesses the rate of fluid consumed daily and the amount of urine excreted over time. The study is carried out separately during the day and night. The daily urine sections are collected as in 8 containers and collect the first and last 4 to determine diuresis day and night. The specific urine weight for each portion is indicated separately, which allows to determine the range of variation of this indicator.
Drug analyzes can also be performed on the fingers and toes to provide a longer window of potential exposure to the hair. However, relatively little is known about how nails process toxins, so it is more difficult to interpret the results. Hair is subject to external contamination problems that may degrade its value, so special preparations may be required for samples in the laboratory in a given case.
In a typical dissection, fluid and tissue samples are collected especially for toxicology testing. The types of specimens collected from the body and the control targets in these biological fluids and tissues are determined by the condition of the disease and the condition of the organism.
Working methods of protein compounds
There are three methods of this kind - qualitative, semi-quantitative and quantitative.
Qualitative research
This method is based on the ability of the reaction of the protein cells to react in a certain way to the reagents used - causing changes in effect, precipitation of the flakes in the urine and turbidity of the liquid.
Upon entering the laboratory, a series of tests will usually be performed in the blood for prescription, prescription and illegal drugs, alcohol and other toxic substances, usually over the counter; for example, metals, inhalants, environment, carbon monoxide, cyanide and many other toxins depending on the control claims or the specific tests requested. Table 3 and the “Systematic Toxicological Analysis” section describes the many materials that a medical professional can collect from the body during an autopsy and how they can be quickly checked in “really unknown” cases.
For such a sample preparing two tubes - the main and the control. Turbidity is determined by continuous illumination of the sample on a black background. In qualitative research Geller methods, boiling, sulfasalicylic acid research (15-20%) and others are used.
According to Geller and using sulfasalicylic acid, qualitative research methods are considered to be the most popular. The latter is most effective for the diagnosis of proteinuria.
Autopsy biological evidence is needed both to support erik generic ”laboratory tests and to investigate some very specific potential causes of death. Routine tests or tests without specific instructions for finding a particular substance will generally include the drugs shown in Table 2 below, but not all drugs. A list of the most commonly used drugs is included in standard binding in all toxicology reports.
Drugs included in routine postmortem toxicology
Additional or special requests to the toxicology laboratory may be made depending on the situation. The most common examples of specific drugs that analysts may request are listed in Table 3 below.
Drugs are usually not included in the study screens of death toxicology.
Depending on the nature of criminal justice in the community, these analysts may work in criminal laboratories, offices of medical experts, state medical laboratories and even independent providers.
Semi-quantitative methods
The most important of these are the use of special, protein-sensitive test strips and the Brantberg-Roberts-Stolnikov method. The latter uses the Geller ring test as a basis, therefore to some extent has the same disadvantages.
Today, semi-quantitative testing studies are continuing. The main reagent of such test strips is bromphenol blue. The amount of protein is determined based on the color of the test strip obtained. Often, this is done visually, but there is a possibility of using special analyzers. The simplicity, speed and convenience of this method unfortunately have a disadvantage - low reliability of the research results. This is because the indicator is maximum susceptible to albumin and reacts relatively weakly to other proteins, so the method is effective in glomerular proteinuria, the prevalence of albumin proteins in urine.
Certification of persons in the United States and Canada as a forensic toxicologist or diplomat is provided by the American Council of Forensic Toxicology. The certificate is based on the candidate's personal and professional records in education and training, experience, achievements and formal expertise. In Japan, the Japanese Toxicology Association has a diplomatic process.
How and where is the analysis performed?
International discussion and participation in toxicology are common. Forensic toxicologists use a number of analytical methods to identify drugs or poisons related to case study; The laboratory's ability to perform routine toxicological analysis will depend on the equipment, specifications, and analyst experience. If necessary, there are special toxicology laboratories capable of testing almost any potential toxin or metabolite in almost all exposed samples.
Quantitative methods
In these methods to determine protein in urine, use:
Sulfate and trichloroacetic acid;
Benzotonium chloride;
Biuret reaction;
Lowry method;
Amburge method;
Nechiporenko method.
Amburge Method
This method is used when the quantitative content in the urine of the formed elements is needed to be measured. The number of these elements in the urine excreted by the patient is thought to be counted within 1 minute.
The laboratory must be accredited for analytical studies and regularly checked by approved accreditation personnel. All laboratory tests must be verified, fully documented and usable. This enables the laboratory to produce accurate and reliable results for medical research. All laboratory tests must comply with standard operating procedures, the results must be in accordance with the standards, and the reported results must be verified by a second toxicologist before publication.
Hambourge's research is prepared using graduated test tubes placed in a centrifuge. Identify the indicators using a pipette, a laboratory counting chamber, and a microscope that collects the sample.
The analyzed urine sample is thoroughly mixed, then 10 ml of liquid is removed and sent to a centrifuge for 5 minutes. After this, the upper part of the liquid is discharged, mixed with the discharged liquid leaving a precipitate in 1 ml, mixed again and placed in a counting chamber. The number of leukocytes and red blood cells in the counting chamber is calculated separately. This method is most effective for outpatient treatment because the autolysis of cells in the collected urine is extremely low.
In fact, the American toxicology community has recently made a two-year effort to develop these standards called the Scientific Toxicology Working Group to address more stringent legal and scientific issues. The immunoassays. The most commonly used drug screening tests include immunoassay methods. Immunoassays are laboratory tests that use antibodies to detect reactions with certain substances. Immunoassay assays are designed to determine whether a sample is positive or negative for the target drug.
Nechiporenko method
It is the most requested method in the counting of urine elements in our country. This popularity of the method is linked to its simplicity and simplicity to laboratory equipment - it can be done in any clinic. In addition, the Nechiporenko method yields very reliable results and has several advantages compared to other methods used for the quantitative determination of sediment in urine. As in the Amburge method, how many cylinders, leukocytes and red blood cells are contained in 1 ml of liquid are considered. The equipment used in the analysis is the same as the Amburge method - a pipette, a microscope, a counting chamber and a centrifuge tube.
Four interpretations of the screening test are possible. When the test accurately detects the presence of a drug, a true positive result occurs, a false positive result is a result in which the test misrepresents the presence of a drug; a false positive result, a true negative result occurs when the test correctly confirms the absence of the drug; does not detect the presence of the drug when it exists. Verification tests should be performed for samples that give positive screening results, preferably using mass spectrometry detection.
The process is as follows:
The urine sample is mixed;
10 ml was selected. in a measuring tube;
The tube is placed in a centrifuge in which it is processed at a speed of 3500 for 3 minutes;
The centrifuged sample is removed from the chamber and the top is removed, leaving 1 ml of the liquid containing the precipitate in the tube;
The precipitate is mixed and sent to the counting chamber.
The sedimentary cells are counted in 1 ml of sediment, typically in the form of leukocytes, erythrocytes and cylinders, each individually. Thus, according to the Nechiporenko method an indication of the shaped elements is obtained.
Specific immunological tests for many drug classes, including all drugs, can be used for some new compounds such as buprenorphine,, Bath salts ”and“ Spices ”and other new synthetic drugs. This is the latest technique used in toxicology to provide evidence of the structure of unknown substances. Learn more about pharmaceutical chemistry ▸.
Systematic toxicological analysis. In general, the application of toxicological examination begins with the identification of alcohol and the screening of a wide range of acidic, neutral and basic organic drugs or poisons. If toxin is detected, confirm and quantitative test if necessary. The quantitative test determines how much of a substance is involved. In general, positive identification is performed using at least two independent assays, and preferably using different test methods.
The advantages of the analysis method are that its preparation is very simple and does not force the patient to prepare for the full hour - the median portion of the morning urine is sufficient. In addition, the Nechiporenko method is highly integrated, applicable to control the dynamics of processes and does not require large amounts of urine for research. For example, a sufficiently small urine portion removed from the kidney using a catheter is sufficient for accurate diagnosis of leukocyte.
The chromatographic verification test can also be quantified by simplifying the test procedure. Acetone may result from abnormal body metabolism under diabetic ketoacidotic conditions. Here are answers to frequently asked questions about donor sperm, sperm donor, sperm donor search, health, safety and more. You can also always.
We update the profile only if there are significant changes in the health of the sperm donor. Profiles include the donor's family history, personal characteristics, and so on. Provides a detailed picture about. this data has hardly changed. The main profiles providing information about the view and a brief description can be viewed directly. However, once you complete your membership, you will be able to access full donor profiles for detailed information such as health and family history, personality tests, and child photos. Information can be shared if necessary, if it can be seen without logging in or entering a password. However, we want to protect the transmitter's detailed information and photos from search engines and possible misconduct. However, if you have a membership, you can only view all available information and photos of children. This email includes ordered products, invoice amount, and order number. All our donors offer high-quality seed units, take advantage of excellent health and have personal interests. The stock of available donor units changes daily as the seeds are sold or added to the stock. Therefore, we cannot guarantee that the units of your preferred transmitter will be available at any time. If you have selected a favorite and only want to use seeds for one or more pregnancies, you can purchase units of this donor in advance and set them up so that they are ready at the right time. Please note that the donor's contact information will only be provided by the donor to his 18-year-old child. This applies only if you are a donor. We can store your purchased seed units for 3 months to 10 years. Purchasing units and creating a warehouse is the best way to ensure the availability of the units of your chosen donor for the current donor and future treatment cycles, as well as for twin children. Please note: If you purchase a unit and store it for a long period of time, if you wish to use these units, the number of pregnancies in your country with donor sperm may have been reached. Once the seeds of the donors leave the warehouse, we can no longer guarantee the quality and condition. Therefore, we cannot send sperm to other doctors or midwives and patients. The right to pregnancy is called y day care for pregnant women bazı in some countries of treatment. Under the right to pregnancy, you are entitled to donor sperm for several children. The right to pregnancy is a measure to limit the number of families with children of a given donor in each country. This means that you have to get the right child for each planned child. Acquired spermatozoa, which have the rights of the child, can only be used to test a child for several treatment cycles, but not for sister witnesses. In order to meet legal requirements for the donor and the total number of children per country, we carefully examine the number of donated sperm and the number of registered pregnancies in each country obtained using units from this donor. Pregnancy reports also include the management of data on registered abortions and the health status of each offspring of donors. The limitation of pregnancy is the reason for choosing your country of origin and the country of origin when looking for donations. If the number of children from a given donor has reached the highest level in the country, additional sperm units will only be sold to families with children with this donor. If you want to separate donor sperm for future treatment, we recommend that you purchase it in advance and in advance. If you want to inseminate at home, home registration is a great way for you to make you feel better at home. In principle, “accessibility ifade refers to the presence in the storage of seed units of a given donor. If you use sperm for fertilization, your child may contact us when they contact a sperm donor after they have been confirmed. This can be a face-to-face meeting, phone call, mail traffic or something else. Contact with the European sperm bank.

Urinalysis is a common method of urine testing for symptoms such as drugs or alcohol.
Occasionally, when the patient is in a terminal state, the doctor urgently requires blood and urine indicators. This laboratory test regimen is called Cito, where a specific urine and blood test is performed within a few minutes.
To pass the urea test at the hospital, you should follow certain rules that will help the doctor determine the condition of the body better after passing such a test when checking the results.
Urine is a product of human activity, which is 95-99 percent of normal water. Other waste products (hormones, slag and other substances) are also excreted in the urine along with the fluid from the body. Therefore, it is thought to be particularly effective in determining the state of human health today. Do without fail in the laboratory in the clinic. It may also conduct other studies in the clinic, such as blood, to help confirm or reject the general results of a prediagnosis of urine.
During examination of urine samples, clinicians may also determine the chemical components of urine. With the help of such a survey, a specialist concludes about the presence of certain components in the urine, and the doctor already determines the diseases of various organs from them.
How to make a urine test in the clinic
It should be noted that in the clinic, its quality is influenced by the products and fluids consumed by a person before proceeding with the seeding analysis. Therefore, for the sowing survey to be as effective as possible, you must prepare for delivery:
For example, it is necessary to abandon crops that can change the color of plantings such as smoked meat.
It is not necessary to drink alcohol, take various dietary supplements and vitamins before going to the clinic for sowing.
When taking any medication, it is important to inform the doctor in the clinic.
It is not necessary to visit the sauna and to place large loads on the body before conducting planting tests.
After cystoscopy, you should not enter the seed for 5-7 days in the clinic.
How much urine is made
This question worries many people who will surrender to cultivation. How many days does such an analysis last? As a rule, the number of days or time of sowing analysis will depend on the circumstances. Most of the experts in the hospital lab test for 3-4 hours. In other words, when you pass the planting in the mornings in the afternoon, you can already get the finished result. In addition, the amount of time or day these exams will be held is affected by other situations. Generally, visitors are warned in advance. In addition, when visiting a laboratory in the clinic, it is recommended that you independently check with experts how much time or day they will need to have the tests ready.
You should only take the fluid in a clean container that is free of dust and dust. It is recommended that you urinate at certain times in the morning or before taking liquids for certain foods.
This will help to make the test more qualitative because the urine will have products in its composition that are released by the body during vital activity without the only other additives. Knowing how much urine analysis is done and how it is done, you can prepare for this procedure in advance.
