Occult Blood – Stool


Urine test for VMA (Vanillylmandelic Acid) and HVA (Homovanillic Acid).



VMA/HVA – 24hr Urine is a test that measures the levels of VMA and HVA in a 24-hour urine sample. Elevated levels of these substances are associated with certain neuroendocrine tumors, such as neuroblastoma and pheochromocytoma. The test aids in the diagnosis and monitoring of these conditions.
