3. Gwajin jin daɗin ƙwayoyin cuta
Da zarar an gano ƙwayoyin cuta, ana yin gwaji don gano mafi ingancin maganin rigakafi. Wannan yana da mahimmanci don hana amfani da maganin rigakafi mara kyau da kuma rage juriya ga ƙwayoyin cuta.
Ilimin ƙwayoyin cuta (microbiology) yana taimakawa wajen gano musabbabin kamuwa da cuta, musamman idan alamomin asibiti suka yi kama da juna tsakanin wata cuta da wata cuta.
6. Binciken Kwayoyin Halitta (PCR da Dabaru na Halitta)
Hanyoyin kwayoyin halitta, musamman PCR (Polymerase Chain Reaction), na iya gano kayan kwayoyin halitta (DNA/RNA) daga ƙwayoyin cuta na ɗan adam ko cututtukan kwayoyin halitta. Waɗannan hanyoyin an san su da mahimmanci kuma takamaiman, wanda hakan ya sa suka zama masu amfani musamman a cikin:
