Urine can be collected in clean plastic bottles (preferably of non-carbonated water).
For certain parameters (catecholamines, VMA, 5HIAA, oxalates, citrates...), urine is collected in special bottles with preservative. On request, a bottle can be obtained in the lab.
For all parameters determined from 24h urine, the urine must be collected exactly 24 hours (it ends at the same time when the collection is started, and the first morning urine is thrown on the first day, and the first morning urine connects with other portions next day), i.e. urine collection begins with second morning urine, and after that all urine portions are collected concluding with the first morning urine the next day.
Bring the total quantity of urine to the lab.
Abstain for 3 to 5 days.
The sample is taken in a sterile glass in the laboratory, and if the sample is taken from home it needs to be transported at a body temperature within 30 minutes.

- The following can be determined from the sample of the stool: bacteria, fungi, parasites, protozoa, toxin Clostridium difficile, Adeno and Rota virus, occult bleeding and calprotectin.
- An analysis of three consecutive stool samples is recommended for the occult bleeding test.
The sample is taken in the morning without treatment of the perianal region the evening before, and that morning.
The sampling site should not be treated with any creams and antiseptics at least 12 hours before taking the sample. Be sure to wash the skin with soap and water before taking the sample.
