1. Collect a gold top serum separator tube via venipuncture.

1. Separate serum from cells.
2. Transfer 1 mL of serum to a clear aliquot tube (screw cap).

• Gross lipemia that cannot be cleared by ultracentrifugation
• Heat-inactivated samples

See patient report.

Patients with injuries, burns, or tumors exhibit elevated concentrations. Patients with chronic renal failure are found to have high concentrations of α1-acid glycoprotein, with no major difference reported between dialyzed and nondialyzed patients. Diminished concentrations due to restricted production of α1-acid glycoprotein are found in patients with chronic liver diseases. Low serum concentrations due to increased excretion of the protein are associated with nephritic syndrome.
