In order for the result of the study to be informative and accurately reflect the clinical picture, it is necessary to correctly prepare for the collection of urine. When collecting daily urine, it is important to consume the amount of fluid that the body is accustomed to. Taking diuretics, non-compliance with the rules for the collection and storage of biomaterial, violation of the diet or drinking regimen can lead to a distortion of the result.
Preparatory stage.
2-3 days before the start of urine collection, you must:
• completely eliminate the intake of diuretics;
• give up spicy, fatty and salty foods, which provoke abundant fluid intake and retain water in the body;
• stop eating vegetables and fruits that can change the color of urine (beets, carrots, etc.);
• drink a norm of pure non-carbonated water - 1.5-2 liters;
• eliminate increased physical activity and fatigue.
Each portion of urine within 24 hours must be collected in a dry, clean container with a volume of 2.5-3 liters. It is advisable to buy in advance a pharmacy plastic container of the required volume with a graduation scale. If it is impossible to purchase, it is allowed to collect biomaterial in an ordinary glass jar. The jar must be thoroughly washed and disinfected before collection.
