How to store tests?
It is useful for almost all people to know how to store tests, and especially for parents of young children. Few people can make the necessary actions to collect biomaterials according to the hours of work of the laboratory of the polyclinic.
If the tests are specific, identifying any specific diseases, then it is best to learn how to store biomaterials from the doctor who prescribes the research data. Most likely, such analyzes will have their own special storage mode. If you pass the usual general tests, you can use our tips.
What capacity to collect
How long can you store tests? The answer to this question depends on the capacity in which you collected feces and urine for storage. Sterile packaging guarantees a longer shelf life. If in the last century, each patient independently fantasized about this topic, found cans of mayonnaise and matchboxes, now one can easily and successfully acquire a special container for all types of tests at the pharmacy. The containers are sterile, hermetically sealed, which allows to obtain the most accurate test results.They cost not expensive and provide an objective reflection of the state of health of the subject.
It is very important to know how much stool analysis can be stored in order to get a reliable picture of the patient's state of health. It is undesirable to store feces for more than 3 hours, during which time feces must be delivered to the laboratory. This is the only way to deal with the collected biomaterial for analysis of dysbacteriosis. If you are assigned a general analysis, you can collect feces from the evening, pack it in a pharmacy container and put it in storage in the lower part of the refrigerator.
A special rule applies to a child�s biomaterial. The kid is not yet able to sit on the pot, much less able to do "his own affairs" at a certain time. Therefore, to collect the feces of the child have to take it from the diaper. It is necessary to gently take the feces with a wand from above, without touching the diapers, put them in a sterile container and store them in the refrigerator for no more than 12 hours. If the analysis is important and the doctor suspects a serious diagnosis, then it is necessary to store feces for no more than 3 hours and take it not from a diaper, but watch for it when the child has a chair. In this case, the accuracy of the results is very important, so everything must be done correctly.
With the urine things are much easier.Practically every person wakes up and goes to the toilet, and small children are no exception. If the mother is responsible, then she will get up earlier than her infant baby, and will catch this important point. Urine should immediately be delivered to the laboratory of the clinic. If the situation is such that it is still necessary to store the urine, then the sterile jar should be placed in the refrigerator, where the temperature is not lower than +4 degrees. The shelf life of urine is up to 24 hours. Note that this rule works in case you need to pass an urinalysis. In other cases, it is important to listen to the recommendations of doctors.
There are such urine tests when the biomaterial is collected during the day. If this needs to be done at home (in exceptional cases), then it must be remembered that all containers should be sterile, banks should be sterilized over steam, bottles should be boiled several times. Plastic containers for the collection and long-term storage (up to 24 hours) urine can not be used!
