Standardized viral hemagglutination and hemagglutination-inhibition tests. I. Standardization of erythrocyte suspensions. [PDF]
A spectrophotometric procedure for standardizing red blood cell suspensions for use in viral hemagglutination tests is described. The procedure is based on highly reproducible cyanmethemoglobin absorbance readings at 540 nm on any suitable ...

The hemagglutination inhibition test for rubella: a comparison of its sensitivity to that of neutralization, complement fixation and fluorescent antibody tests for diagnosis of infection and determination of immunity status. [PDF]
The hemagglutination inhibition (HI) test for rubella was compared to neutralization, complement fixation (CF) and indirect fluorescent antibody (FA) tests for sensitivity in the serodiagnosis of infection and detection of antibody elicited by past ...
