Urine samples are easily obtained
Explanation:
- Urine samples can be used to test the hormones as well as their metabolites present in the body.
- Besides urine several other things can be used to test hormones such as using blood , saliva etc.
- However urine sample collection has an advantage over the blood samples because it is easier to collect urine rather than blood, one does not require needles, and other sterile things required for blood collection but all such complex things are not required for urine sample collection.
- All one needs to collect urine sample is a simple urine collection vial that is sterile and the sample volume is sufficient to perform the hormone tests, thus it is not invasive in any manner.
