The enzyme immunoassay diagnostic procedure was first described in 1971.
enzyme immunoassay (EIA)
GST was detected by enzyme immunoassay (EIA) and ALT and AST by routine biochemistry methods.
The HBV markers and HBV DNA in poultry sera, Yolk and bovine milk whey were detected by reversed passive hemagglutination assay (RPHA), enzyme immunoassay (EIA) and polymerase chain reaction (PCR).
Electrochemical luminescence immunoassay method was used to detect CA153, CA199 and CA125, and particle enzyme immunoassay method was used to detect SCC.
