Immunochemical determination of serum albumin with a centrifugal analyzer
M Blom et al. Clin Chem. 1975 Feb.
Abstract
The turbidity resulting from the reaction between albumin and specific anti-human serum was measured with a good precision by using a GEMSAEC centrifugal analyzer. The reaction was enhanced by polyethylene glycol to shorten the reaction time (5 min) and to displace the point of equivalence between antigen and antibody to an albumin concentration unlikely to occur in human sera (about 100 g/liter). An additional program for the computer was necessary to fit the absorbance readings of individual sera to the nonlinear standard curve. Serum albumin values obtained by the described method correlated well with values obtained by the electro-immuno-technique. About 100 samples could be analyzed per hour, 500 mul of 100-fold diluted antiserum being used per specimen.
