Rules for preparing for the tests
Clinical and biochemical blood tests
Blood sampling is recommended to be performed on an empty stomach and in the morning. 12 hours before the test, do not eat fatty foods. It is advisable not to eat for 4 hours at all, as a high concentration of fats can distort the results, and in some cases lead to the inability to perform the research. Blood tests for the level of hormones are recommended to be taken before 12:00 am, as their concentration varies cyclically throughout the day. For women, when registering, you must specify the day of the menstrual cycle or the week of pregnancy. Before taking blood, do not smoke for at least 30 minutes, and alcohol consumption must be eliminated for 72 hours before the test. Stress and exercise are another factor that influences the results of tests. Therefore, to exclude their influence, it is necessary to take a comfortable pose (sit down) for a few minutes before taking blood, relax and calm down. Drugs are also excluded. If this is not possible for any reason, please inform the laboratory about this.
Clinical tests of urine
12 hours before the test, exclude from the ration spicy and salty foods. As far as possible, exclude the use of diuretics for 48 hours before urine sampling. Deliver to the laboratory morning portion of urine, sampled after a careful toilet of the external genital organs in clean dry dishes. Women should be examined before the beginning of menstrual period or 2 days after the end of menstruation. The container with urine should be tightly closed with a lid and delivered to the laboratory. A container for urine can be purchased at any of the point of Nikolab.
Nechyporenko test of urine
12 hours before the test, exclude from the ration spicy and salty foods. Exclude also the use of diuretics for 48 hours before urine sampling. Women should be examined before the beginning of menstrual period or 2 days after the end of menstruation. After a careful toilet of the external genital organs the average portion of urine is sampled: for this, the first portion of urine is released into the toilet, the middle one into the prepared clean container, the latter into the toilet.
Zimnitsky test of urine
12 hours before the test, exclude from the ration spicy and salty foods. Exclude also the use of diuretics for 48 hours before urine sampling. The sampling is carried out with the usual drinking and nutrition regime. 8 samples of urine are sampled per day for Zimnitsky sampling. At 6:00 AM the bladder gets emptied (this portion pours out). Then, starting at 9:00 AM, exactly every 3 hours, 8 portions are sampled in separate containers (until 6:00 AM the next day).
Attention: one portion is all the entire released urine at a time!
On each container there is a time of urine sampling. If the urination was absent in any of the time intervals, then this container remains empty and as well as all other portions, should be delivered to the laboratory. All containers with urine should be stored in a cool place without freezing.
Daily urine test
12 hours before the test, exclude from the ration spicy and salty foods. Exclude also the use of diuretics for 48 hours before urine sampling. The sampling is carried out with the usual drinking and nutrition regime. Women should be examined before the beginning of menstrual period or 2 days after the end of menstruation. Sampling of urine begins with the fact that the first morning dose, after waking up, is released into the toilet, and all the next ones are collected within 24 hours in a clean container with a volume of at least 2 liters. The urine should be stored in a cool place without freezing. The urine collected in this way is thoroughly mixed for 24 hours and its full volume (daily diuresis) changes. Then at least 15 ml of urine is poured into a sterile disposable container and delivered to the laboratory on the same day.
Urine test for cortisol and metanephrine
Daily urine is sampled for this study. Before starting the sampling, you need to contact any of the points of Nikolab to obtain a preservative. First, a preservative is added to the sampling container, and then urine is released. A sterile disposable container is filled with at least 15 ml of urine sampled per day and delivered to the laboratory on the same day.
Clinical tests of feces (Coprogram)
Before collecting the feces it is recommended to exclude the intake of laxatives, rectal suppositories and oils. Feces are collected in a sterile disposable container with a help of a spoon from three places (beginning, middle and end of defecation) and delivered to the laboratory on the same day.

Exclude the intake of laxatives, rectal suppositories and oils. It is not recommended to brush the teeth, so that mechanical damage to the gums does not provoke blood flow into the intestine. Feces are collected in a sterile disposable container with a spoon from three places (beginning, middle and end of defecation) and delivered to the laboratory on the same day.
Feces test for eggs of helminths and protozoan cysts
The excretion of helminth eggs and protozoan cysts depends on the life cycle of the parasites. Therefore, the results of studies may be negative even if there is an infection. Thus, for the reliability of the results, a three-time study is recommended with an interval of 3-7 days.
The sampled feces are taken from the three parts of the last portion and delivered to the laboratory on the same day.
