1. Why is a 24 hour urine sample required?
The amount of VMA excreted in the urine fluctuates during the course of a day. By collecting all the urine for 24 hours, the average amount of VMA can be measured which is a better indicator of whether levels are increased or not.
2. Will medication affect the levels of VMA?
Certain drugs can increase or decrease the levels of VMA. However, prior intimation before sample collection and interpretation of test results is useful.
3. Why are some people at a higher risk for developing a pheochromocytoma or neuroblastoma?
People with a family history of multiple endocrine neoplasia (MEN2), a genetic condition are at higher risk for developing a pheochromocytoma and developing it at a younger age.
