I Umfundi we-elisa luvavanyo lwe-immunoassay oludityaniswe ne-enzyme.Sisixhobo esikhethekileyo se-enzyme-linked immunosorbent assay, ebizwa ngokuba yi-microplate detector.Inokwahlulwa ngokulula ibe ziindidi ezimbini: i-semi-automatic kunye ne-automatic ngokupheleleyo, kodwa imigaqo yabo yokusebenza iyafana.Ingundoqo i-colorimeter, ngamanye amagama, uhlalutyo lwe-colorimetric lusetyenziswa.Ukuzimisela ngokubanzi kufuna umthamo wokugqibela wesisombululo sovavanyo ube ngaphantsi kwe-250μL, kwaye uvavanyo alukwazi ukugqitywa nge-photoelectric colorimeter ngokubanzi, ngoko kukho iimfuno ezikhethekileyo ze-photoelectric colorimeter kwi Elisa umfundi.
