How much urine is needed? For the analysis of urine by Nechiporenko, the lab technician separates from the entire volume one milliliter of liquid. It is this amount that is 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,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 need to finish urinating in the toilet.

Research on Zimnitskiy

How much need to collect urine to conduct thisstudy? Analysis of Zimnitsky suggests fluid diagnostics, 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 about 150-300 milliliters of liquid.

To carry out the diagnostics, a laboratory assistant from eachthe jars release about 10 milliliters of urine. 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 exercisediagnostics? A person should collect from one to two liters of material. You do not need to deliver the entire 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 usethe received dose completely. They take about a third of the volume and conduct 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 the presence of 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, youan average dose of morning urine is required. 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, a portion of the allocatedbaby fluid can be significantly less. So, if a person needs to collect 100 milliliters for a general analysis, 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 should be carried out atnewborn, then the portion can be even smaller. Kids of the first month of life can only urinate for 10 milliliters at a time. This amount of fluid will be enough for diagnosis. Only in some cases the doctor can appoint the collection of two different portions of material in one container.

Is it possible to pass a larger amount?

In most cases, patients do not haverepresentations about the specified norms. They take 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 portionsfor 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.
