Laboratory studies cause in patientsa lot of questions: "when to pass this or that analysis," "how to prepare for it," and so on. This article will answer all questions about 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.
Before you know how much urine is needed forurine analysis, it is worth saying that this study is one of the most common. Most doctors prescribe this diagnosis at the first reception. 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.
Depending on what kind of diagnosis you needthe method of collection and the amount of material studied 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 what,how much urine is needed for the analysis of 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.
This study involves the collection of the morningportions of 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 quite80-130 milliliters is enough. If your packaging is much less than the amount allocated, then it is worth collecting the urine in a separate container and then pouring the necessary part.
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.
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.
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.
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.
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.
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.
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.
