Special Info

Drugs and medications may affect results and should be discontinued for at least 72 hours prior to specimen collection, if possible. Catecholamines are not stable above pH 7. The pH of such specimens must be adjusted by the addition of 6M HCl acid or sulfamic acid prior to transport. A pH less than 2 can cause assay interference. Record total volume and collection time interval on transport tube and test request form. Specimen preservation Option 1: Transfer a 4 mL aliquot (Min: 2.5 mL) to an ARUP Standard Transport Tube. Adjust pH to 2.0-4.0 with 6M HCl. Specimen Preservation Option 2: Transfer a 4 mL aliquot (Min: 2.5 mL) to an ARUP Standard Transport Tube containing 20 mg sulfamic acid (ARUP Supply #48098), available by contacting Client Services at 800.628.6816 or 216.444.5755 (Min: 2.5 mL). Room temperature specimens, specimens preserved with boric acid or acetic acid, or specimens with pH > 7 will be rejected. This test is New York DOH approved.

Clinical Info

This test is useful to evaluate clinical symptoms of excess catecholamine secretion. Not recommended for evaluation of paraganglioma or pheochromocytoma. The optimal specimen for this testing is a 24-hour urine collection.
