Laboratory normals: Your question cannot be answered unless we know the following: 1. What laboratory did the tests and what are their normal reference ranges. 2. Did you take any medications that could interfere with the assays? 3. Did you have any foods that might interfere with the assays? Also, why were these tests done? If you are looking for a pheochromocytoma, they might help. Otherwise, probably not.
