Immunoturbidimetric assay for alpha 1-acid glycoprotein in serum with a centrifugal analyzer

This is a simple immunoturbidimetric method for the rapid assessment of alpha 1-acid glycoprotein in serum with the "Flexigem" microcentrifugal analyzer. Results obtained for a pediatric population (n = 95) agree with those by radial immunodiffusion (x) and yield the regression equation: y = 1.4x + 0.017 (r = 0.98). Results are printed automatically after a procedure that takes only about 15 min. Within-run precision (CV) ranged from 2.2 to 2.5% for concentrations of 0.35 to 2.4 g/L. Day-to-day CV was 4.25% for an average concentration of 0.9 g/L.
