Quantitation of DNP, digoxin, HCG and anti-DNP antibody by electronic data processing of latex antiglobulin reaction results

Volumes of agglutinates produced by the microtiter latex antiglobulin test (LAGT) were measured by an electronic data processing (EDP) method using a particle volume distribution analyzer. This method proved highly sensitive for quantitating weak antibodies, such as anti-digoxin and anti-DNP. EDP measurement of the microtiter latex antiglobulin-inhibition test (LAGIT) is also a suitable method for quantitating HCG, digoxin and DNP.
