1-2 days before urine collection, it is important to exclude factors that can distort the test results:
- food products that can discolor urine (for example, brightly colored fruits, vegetables and dishes made from them, smoked meat, sweets and marinades);
- alcohol, taking vitamins, dietary supplements, diuretics;
- serious physical activity, bath and sauna.
Menstruation, an infectious disease with temperature rise, or a significant increase in blood pressure - are the reason for rescheduling the test.
The urine is collected in disposable sterile containers available at any pharmacy. Thorough hygiene of the external genital organs must be carried out before urinating.
There are several types of urine tests:
- Nechiporenko urine test;
- clinical urine test;
- bacteriological urine test.
For the Nechiporenko urine test, an average portion of morning urine is collected immediately after sleep. The urine is collected in a special container that can be bought at the pharmacy.
Before collecting urine, wash the external genitalia. Women do it from front to back with a mild soapy solution. The test is not performed during the period.
After hygiene procedures, you should start urinating into the toilet, then hold it back and excrete urine into a special container in an amount of 10-20 ml. After this, urination is completed in the toilet. Collected urine is sent to a laboratory for analysis.
For the clinical urine test, it is necessary to collect all the morning urine, mix it thoroughly, and pour about 50-100 ml into a sterile container. The container should be delivered to the laboratory as soon as possible, since the analysis must be performed within 2 hours after urine collection.
For the bacteriological urine test, an average morning portion of urine (in a volume of 10-20 ml) is used being collected in a special container in compliance with sterility conditions and delivered to a medical laboratory. Urine must be taken before starting antibiotic therapy or 3 days after it.
Before collecting urine, thorough washing of the external genital organs and the anus area is carried out with warm boiled water. Men need to pay special attention to the washing of the urethral opening, and women - the vaginal vestibule. Disinfectants should not be used during washing, as they can inhibit the growth of microorganisms if they enter the sample.
