Avoid hemolysis. False elevations may occur in specimens which are not processed promptly to separate serum from RBC's.

Test Limitations:
Criterion: recovery plus or minus 10% of initial values Plasma Icterus: No significant interference up to an I index of 60 (approximate conjugated and unconjugated bilirubin concentration: 60 mg/dL). Hemolysis: RBC contamination elevates results; interference if H index is greater than or equal to 50. Lipemia (Intralipid): No significant interference up to an L index of 900. There is poor correlation between turbidity and triglycerides concentration. Highly lipemic samples may cause ABS! flags.
Methodology:
UV Assay
Sample Processing:
Centrifuge at a speed and time necessary to get barrier separation
of plasma/serum and cells within 1 hour of collection. Send specimen
in original tube. Do Not transfer to another tube.
Each sample must be labeled with at least TWO full patient identifiers (First/Last Name & DOB are sufficient for non-UIHC affiliated clients) to avoid sample rejection/delays.
