Serum Separator Tube (SST).
Allow specimen to clot completely at room temperature. Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL)
EDTA or heparin plasma. Hemolyzed specimens. CSF (refer to Angiotensin Converting Enzyme, CSF test code 0098974).
After separation from cells: Ambient: 1 week; Refrigerated: 1 week; Frozen: 6 months
0-6 years: 18-90 U/L
7-14 years: 24-121 U/L
15-17 years: 18-101 U/L
18 years and older: 9-67 U/L
Note: Measurement of ACE activity for the evaluation of sarcoidosis is not reliable when ACE inhibitors are present. Serum ACE activity is markedly reduced in patients on ACE inhibitor therapy.
