How much urine is needed to analyze urine? Required volume of urine for analysis

Laboratory studies cause a lot of questions in patients: "when to pass this or that analysis," "how to prepare for it," and so on. This article will give an answer to all the question of how much urine is needed for urine analysis. You will find out what are the features of collecting material for conducting a particular study. Also find out what is the minimum amount of urine for a general analysis.

Urine examination

Before you know how much urine is needed to analyze urine, it is worth saying that this study is one of the most common. Most doctors prescribe this diagnosis at the first admission. The essence of the research may be different.

The most popular is the general analysis of urine. For more detailed diagnosis, a study is conducted on Nechiporenko, Zimnitskii, Sulkovich, and so on.

How much urine is needed for analysis?

Depending on what kind of diagnostics you are assigned to, the method of collection and the amount of material to be examined can be different. Thus, the volume of urine for urinalysis in general in an adult and a child may be significantly different. What can we say about newborn babies.

Most often a person does not think about how much urine is needed to analyze urine, and fills the jar to the top. However, this is not always required. Let's try to understand how much urine is needed for urine analysis of various kinds.

General research

This study assumes the collection of the morning portion of the secreted fluid. In this case, you need to put the material completely in the jar. Normally, a person in the morning hours is allocated from 100 to 200 milliliters of fluid.

For the diagnosis will be enough 80-130 milliliters. If your packaging is much smaller than the amount allocated, it is worth collecting the urine in a separate container and then pouring the necessary part.

Research on Nechiporenko

How much urine is needed? For the analysis of urine by Nechiporenko, the lab technician separates from the entire volume one milliliter of liquid. This is the number required to determine the level of leukocytes, red blood cells and cylinders. However, this does not mean that you can bring a few drops of urine to the laboratory.

To study the material by Nechiporenko, you need to pass from 50 to 70 milliliters of liquid. Thus the portion of urine should be average. This means that the first jet of liquid must be released into the toilet bowl. After that, the material is collected in a jar. You must finish peeing in the toilet.

Research on Zimnitskiy

How much urine should be collected to conduct this study? Analysis Zimnitsky suggests fluid diagnosis, which is released during the day. The main condition is the collection of material every three hours. Absolutely all portions are collected in sterile containers. A healthy person during the day produces from one to two liters of urine. Therefore, in one container you should fit approximately 150-300 milliliters of fluid.

To carry out the diagnostics, the lab worker extracts about 10 milliliters of urine from each jar. It is in this volume that research is carried out. From this it can be concluded that for diagnosis, only 80-100 milliliters of collected material is needed.

Study to determine the content of glucose, protein and creatinine

How much urine is needed for this type of diagnosis? A person should collect from one to two liters of material. Thus it is not necessary to deliver the whole volume to the laboratory. Diagnosis involves the collection of all the released fluid, which is placed in one large container. After this, it is necessary to separate 100 milliliters from the received volume and deliver them to the laboratory.

During the study, doctors do not use the received dose completely. They take about a third of the volume and carry out diagnostics. It is worth noting that for each analysis you need to take the specified dose. So, if you are assigned to examine urine for glucose, then 100 milliliters of daily allowance is surrendered. Each additional study assumes the addition of the said portion.

Bacteriological study

For this diagnostic procedure, you need an average dose of morning urine. Collect it you need in an amount of 50 to 70 milliliters. It is this dose and investigate the laboratory for sensitivity to antibiotics.

To find out the state of the flora, the doctor will need only 10 milliliters of material. In this volume, microorganisms are populated, which subsequently give or do not give rise.

The amount of urine a child has for diagnosis

Unlike adult norms, the portion of the allocated liquid of the baby can be much less. So, if a person needs to collect 100 milliliters for a general analysis, then the baby will be 20-50 enough. Remember: the lab assistant can not refuse you in the analysis because the material is not enough.

If the study needs to be carried out in a newborn, then the portion may be even smaller. Kids of the first month of life can only urinate for 10 milliliters at a time. This amount of liquid will be enough for diagnosis. Only in some cases the doctor can prescribe the collection of two different portions of material in one container.

Is it possible to pass a larger amount?

In most cases, patients have no idea about these standards. They pass from 100 to 150 milliliters at a time. However, no one says that there is too much material for research. The laboratory assistant will separate the necessary quantity and carry out the research.

Summarizing

So, now you know the basic norms of portions for the analysis of urine. Remember that in some cases the material is not enough. An incorrect diagnosis can be made for this indicator. That is why when getting directions, it is worthwhile to check with a specialist how much it is necessary to collect urine for research. More than the specified amount you can pass, less - extremely undesirable.

Strong to you health and good diagnostic results!
