Urine according to Zimnitsky during pregnancy is most often prescribed for suspected disorders in the functioning of the kidneys.
When assigning this analysis, the rules for collection and delivery are different: the collection takes place at strictly defined hours, and the portions are not mixed, each is stored in its own jar. All jars are delivered to the laboratory.
Prepare 8 containers. The first time you should go to the toilet at 6 o'clock in the morning, this portion does not need to be collected. The time of the first urination should be recorded. Then the scheme is as follows: the day is divided into 8 time intervals of 3 hours. All urine excreted within 3 hours is collected in one container.
1 9:00-12:00
2 12:00-15:00
3 15:00-18:00
4 18:00-21:00
5 21:00-24:00
6 00:00-03:00
7 03:00-06:00
