question: Hello doctor, I had a random urine test for pheochromocytoma and I think my PCP is reading wrong. I went to the lab and gave an ambiguous report confusing people. She did say fourfold elevation normetanephrine and four-fold elevation u-metanephrine. I do have episodic severe hypertension attacks, palor, sweating, BP up to 256/131 mmHg for 20 minutes or so. Only very occasionally have these attacks. As a 50 year old I never had sustained high blood pressure but now I do and am on large doses of medicines. Do I have elevated lab work and what do you think it means? U-metanephrine total QST 196 range 149 to 603. U-normetanephrine QST 148 range 108 to 524. U-epinephrine QST was below reportable range. Rest of numbers seem normal. What is your opinion?
