Alias:

ACE (Angiotensin Converting Enzyme) Angiotensin-1-Converting Enzyme Kinase II Peptidylpeptide Hydrolase SACE (Serum Angiotensin Convert, Angiotensin-1-Converting Enzyme, Kinase II, Peptidylpeptide Hydrolase, SACE (Serum Angiotensin Converting Enzyme), Sarcoidosis, Serum Angiotensin Converting Enzyme, ACE (Angiotensin Converting Enzyme)

Performed:

Monday-Friday 8:00a to 10:00p
Saturday-Sunday 9:00a to 5:00p

Analytical Time:

3 hours

Testing Laboratory:

Pathology Laboratory

Laboratory Section:

Core Laboratory

Angiotensin Converting Enzyme

Preferred Collection Container:

Light Green (Lithium Heparin Plasma Separator Tube)
SST (Serum Separator)

Also Acceptable Collection Container:

Green No Gel (Lithium Heparin)
Red (No Additive)

Collection Information:

Collect blood in a Light Green (Lithium Heparin Plasma Separator Tube) or SST (Serum Separator) tube. Green No Gel (Lithium Heparin) or Red (No Additive) also acceptable.

Transport Information:

Centrifuge and aliquot 0.5 mL of serum or plasma into a plastic transport vial. Send refrigerated.

Minimum Sample Volume: Minimum amount of analytical sample (serum, plasma, urine, CSF, etc.) required to perform an assay once. Submitting the minimum volume makes it impossible to repeat the test or perform confirmatory or reflex testing. In some situations, a minimum specimen volume may result in a QNS (Quantity Not Sufficient) result, requiring a second specimen to be collected.
