On the eve of the test, it is recommended to refrain from intense physical activity, do not eat a lot of meat products, salty, sour and spicy foods, as well as coloring foods (beets, carrots, etc.). This can lead to a distortion of the result - the appearance of protein and salts in the urine. For a general urinalysis, it is preferable to collect the morning portion of urine.
A thorough toilet of the external genital organs is preliminarily carried out with warm water and soap. It is better to close the vagina with a cotton swab to prevent secretions from entering the urine sample. Urine is collected in a clean, dry container. For analysis, an average portion of urine is used, that is, for the first few seconds you need to urinate into the toilet, then into a jar, and the remains again into the toilet.
It is necessary to deliver urine to the laboratory within two hours from the moment of sampling and it is advisable to try not to subject it to strong shaking during transportation. It is allowed to store urine in the refrigerator at a temperature of +2-+4 degrees, but not more than 1.5 hours. It is desirable that the amount of material collected for the study be at least 70 ml.
