Abstract

The present invention relates to an optical apparatus and a uniaxial method for rapidly measuring spectroscopically labelled specific binding analytes in a reaction assay mixture that contains unbound label without requiring the physical separation of the unbound label from the reaction mixture or sequential reagant additions and incubations. Moreover, the technique is equally applicable to measurements in either serum or whole blood.
