A sample is taken before any dose to calculate the percentage of the drug in the lowest level (Trough) Then another sample is taken after taking the drug (it differs from one drug to another) to calculate the highest level of the drug in the blood (Peak) in order to make sure that the effective dose is without reaching drug poisoning.

It is preferable to wash the genitals with water, then dry them, then empty the first drop of urine into the toilet, and put the rest in the cup provided by the laboratory.
