How much can the stool analysis be stored in the refrigerator? Storage Rules

Modern people have long been accustomed to the furious pace of life. Each of them chooses for himself the best way of rational use of time. And most often they save precious hours on their meals (snacks on the go, lunches in the fast food cafe, skipping meals during the day). All this leads to various kinds of diseases of the gastrointestinal tract. Do not ignore problems with the intestines and wait until everything goes by itself, as this can contribute to the development of serious diseases.

Coprogramme

Often in case of problems with the digestive tract, in order to make a correct diagnosis, it is necessary to make a laboratory study of excrement - a coprogram. The results of this survey contain important data on the state of human health. And their reliability directly depends on the quality of the material being studied. It is very important to know how to properly store and collect feces.

The rules for collecting

1. It is necessary to prepare a sterile container.
2. It is necessary to empty the bladder.
3. Using soap or furacilin, the surface of the genitalia should be treated.
4. It is necessary to select the necessary amount of material for analysis, place it in a container and close it tightly with a lid.

And how much feces do I need for analysis? The amount of 1-2 tea leaves will be enough.

Conducting the collection of feces is necessary in the morning, on the day of the test. The selected material should be delivered to the laboratory within an hour.

The procedure can be carried out in the evening, but taking into account that the interval between collection and delivery of material for analysis does not exceed eight hours. However, in this case the question arises: "And how to store the analysis of feces?" Now we'll figure it out.

Storage conditions

Since the temperature from +4 to +8 degrees is optimal for storage of fecal matter, it is best to keep the stool in the refrigerator.

The container with the analysis should be placed on the middle shelf. Do not place it on the door shelves or too close to the freezer. This is due to the fact that the feces completely lose all their original properties during freezing. Then the results of the tests will be incorrect.

How much to store?

Among medical workers, there are often disputes about how much stool analysis can be stored in the refrigerator. Variants of the answer to this question can be the most diverse. To obtain reliable results of the study, you should consider how much stool analysis can be stored in the refrigerator. And it will depend on the purpose of delivery of this analysis.

So, for example, for carrying out an ordinary coprogram the material is allowed to be stored for no more than 8 hours. Of course, the actual location in the refrigerator of a container with assays should be less. After all, you need to take into account the time for the journey to the laboratory.

How much can the stool analysis be stored in the refrigerator? To analyze the definition of intestinal microflora, feces must be delivered no later than three hours, and it must be collected in the morning. This is due to the fact that the lifetime of many bacteria is low. Therefore, they can not stand long storage. If the delivery deadline is violated, the results will be unreliable.

How much can a feces analysis be stored? For example, stools intended for analysis for the presence of worms, amoebas, lamblia are also not subject to long-term storage. The container with the material must be submitted for examination no later than six hours after the defecation. However, many laboratory workers believe that you can store no more than two hours. Therefore, in order to determine exactly how much feces should be stored for worms, it is necessary to consult a laboratory before passing it.

If a test is performed for concealed blood, fecal masses can be stored in the refrigerator for no more than six hours. At the same temperature should be from +4 to +6 degrees.

If there is no possibility to take a feces

In the case when there is no possibility to collect and deliver the feces in time to the laboratory, it is possible to resort to another method, more precisely, to scrape off the mucosa of the intestine. In this case, the material will be taken with a cotton swab, which is placed in a hermetically sealed tube and sent to the laboratory within two hours.

Soskob is mostly taken from children. It is impossible to completely replace the process of collecting stool with this procedure. Because most diseases can not be detected in this way. Which way to take the test, you should check with your doctor.

It is necessary to follow the rules!

Many people who are prescribed this medical examination simply do not appreciate the generally accepted rules for collecting and storing stool. The results of this negligence can be very different. Indeed, in the case of long-term storage, a large number of bacteria simply die, and the remaining microorganisms, on the contrary, begin to multiply. The same thing happens when the material is frozen. The results of such an investigation will initially be incorrect.

The likelihood that the attending physician will be alarmed by the results of the tests and he will send you for a second investigation is rather small. Most often, just the wrong treatment is prescribed. As a result, the problem with which the patient addressed, not only does not disappear, but can lead to a serious complication or development of a new disease.

Features of collection and timing of storage of analysis of feces of an infant

Almost all infants up to three months of age are troubled by colic and bloating. This time, young parents just need to survive. However, if the child has been more than four months old, and the problem has not disappeared and, in addition to it, the child's chair has become a greenish tinge or impurities of blood and mucus, then it is necessary to immediately contact the district pediatrician.

In this case, in order to correctly determine the diagnosis and prescribe a treatment, the doctor usually gives directions for the delivery of the feces of the baby for tests.

The process of collecting feces from the baby is rather difficult. Therefore, parents have to go to a number of tweaks to do it.

To begin with, it is best to store a feces special capacity, which is sold in any pharmacy. It is necessary to collect stool in the morning. If a child every day croaks in the morning, at a certain time, then this greatly simplifies the task.

Since it is not possible to wash a child immediately before the defecation process, you should simply carry out daily hygiene procedures. Provided that the child's chair is of normal consistency, it can be collected from the surface of the diaper. Do not press on the diaper so that no foreign impurities enter the material for analysis, and urine. If the chair is liquid, then the child is best placed on an oilcloth, from which it will then be possible to simply pour the feces into a jar.

Delivery of the container with analyzes to the laboratory is necessary within three hours after the sampling. At this time, store the container in a refrigerator, sealed.

Conclusion

Now it is clear how much stool analysis can be stored in the refrigerator. Summarizing all of the above, it can be concluded that it is important to follow the rules for collecting and storing the material in order to obtain the most reliable result. Of course, the best option would be to immediately transport the analyzes to the laboratory. But if this is not possible, then you should place the container in the refrigerator, taking into account all the rules. This will avoid the possibility of assigning the wrong treatment, as well as eliminate the need for repeated collection of analyzes.
