How much urine can be stored for analysis in the refrigerator?

Very often people are interested in how much urine can be stored for analysis. For example, in the refrigerator. The fact is that this issue is extremely important. Collection of biological material and its provision to the laboratory are processes that seriously affect the final results of research.

Many hospitals and medical centers take urine tests only in the morning. So, there are some restrictions. So what about the storage of this biological material? How much and how should I store it to get the most accurate result?

Properties of urine

To begin with, it is worthwhile to understand that urine has some specific properties. They seriously affect the results of research. That's why citizens are interested in how much urine can be stored for analysis.

Urine quickly loses its properties. After a while, a sediment can form in the urine. Because of this, the informative nature of the analysis decreases many times, and it will not be possible to call such an investigation correct.

After a certain period, urine begins to be enriched with ammonia. Because of this, serious inaccuracies in the analysis may occur. It is necessary as soon as possible after the collection of urine to take her to the laboratory for further research. But not always and not everyone has such an opportunity. What should I pay attention to in the first place? How much urine can be stored for analysis, and under what conditions?

The faster the better

It is recommended that you do not do this at all. Urina will give the most accurate results only if it is fresh. Therefore, some citizens do not care about its storage term. Especially those who are close to laboratories.

It is recommended to follow the rule, which states that after collection of biological material in a special container, it is necessary to take it as soon as possible for further investigation.

Informative

But still how much urine can be stored for analysis? At room temperature, for example. It has already been said that it is required to take the collected material for research as soon as possible. But how much time is given to a citizen to ensure that the results are as accurate as possible?

On average, urine retains its informative value for 1.5-2 hours from the time it was collected, at room temperature. After that, the process of ammonia and sediment release begins. Accordingly, as soon as a citizen has collected biological material, he will have only 120 minutes to deliver it to the laboratory. But this is far from the only variant of the development of events.

Quite often, the extension of informativeness is achieved by storing urine in the refrigerator. This is a common phenomenon, which should be taken with special responsibility.

Fridge

How much urine can be stored for analysis in the refrigerator? It has already been said that this is a good option for the extension of informativeness.

Ideally, when storing urine in a refrigerator, you can keep the accuracy of the indicators for another 2 additional hours. But, again, it is best not to delay and as soon as possible to take the analysis for the study.

It would seem that it is clear how much urine can be stored for analysis. But, frankly, the answer is not limited to two hours. Parents and doctors have different opinions about this. What other variants of the development of events can occur?

Dependence on analyzes

For example, an important nuance is what kind of analysis will be conducted. In some cases, it is necessary to deliberately wait for "delinquency" of biological material. But at the same time store urine directly in the refrigerator.

Under certain circumstances, you can deliver urine to the laboratory 10-12 hours after collection. For example, if an analysis is carried out for Kakovsky-Addis. This study involves the collection of urine throughout the day. Accordingly, on average, it is stored in the refrigerator for half a day. And there is nothing wrong with that. But at room temperature the informativity of the analysis is lost.

Night gathering

Let's continue to find out how much urine can be stored for analysis in the refrigerator. A child or an adult should be examined, but, as already said, it is best to collect urine in the morning and to take it to the laboratory as soon as possible in general and clinical studies. Maximum - put for 2 hours in the refrigerator.

But it happens that it is very problematic to collect biological material from a baby. For example, if there are violations of the kidneys, and he rarely urinates. In this case, it is recommended to take a fence before going to bed.

How much urine can be stored for analysis (child or adult - not so important)? Under similar circumstances it is allowed to store about 8-9 hours at a temperature of up to 4 degrees Celsius.

By the way, it is important to report this to the laboratory when handing over the biological material. And a note is made on the container that the urine was stored in the refrigerator. If possible, the time for collection of biological material is also put. Otherwise, the citizen will receive inaccurate results. Accordingly, it is allowed to store urine throughout the night. But in the morning, as soon as possible, biological material is transported to the laboratory. If you can collect the morning urine, then the old one can be disposed of. And the analysis is required only in a new container.

Freezing

Now it is clear how much urine can be stored for analysis before handing it over to the laboratory. But some are wondering whether it will be possible to prolong the informativeness of urine, if you use a freezer. After all, most of the products are freeze enough to be stored for a long time.

Doctors point out that urine should not be frozen in any case. So it completely loses its properties. If there is no possibility of rapid delivery of collected biological material to the laboratory, it is better to place the container with it in a dark and cool place. But not in the freezer. Accordingly, you can forget about freezing. Keep urine at minus temperature can not even an hour.

In pregnancy

How much urine can be stored for pregnancy analysis? At the moment, this procedure is not required at all. The fact is that there are various tests for determining pregnancy at home. They allow even without collecting urine to determine whether the girl has an "interesting" position.

If you want to use an ordinary express test, you'll have to collect the morning urine in a small container. Further, the test strip is dropped to a specific label. In a few seconds you can get the test, and urine - pour.

If it is necessary to store it for a while (for example, because there is no test for pregnancy at home), then it should be done according to generally accepted rules. In other words, after the collection should not take more than 2 hours. In the refrigerator it is desirable not to place urine. After all, informative content in this case is reduced. And in the early stages of pregnancy because of this situation, the test may be negative. And this factor must be taken into account.

The rules for collecting

The last thing to pay attention to is the rules for collecting the material for analysis. With improper fence technology, you can not worry at all about preserving the informativeness, due to the long storage. After violations in the collection lead to a complete loss of the effectiveness of the study.

It is recommended to collect urine according to the following tips:

1. The most informative is the morning. Therefore, the fence should be performed in the morning, in the first emptying.
2. Use only special containers for collecting urine. Old or used containers are not accepted.
3. The technique of collection is as follows: first 2-3 seconds to empty into the toilet, then 3/4 of the container is filled with urine, the rest - again in the toilet.
4. A few days before the collection of urine is to exclude the use of drugs, as well as spicy, sweet and salty foods.
5. After collection urine can not be overcooled. It is required to close the container immediately, so that particles do not get into it from outside.
