[Rauni]
– Yana buƙatar kayan aiki masu tsada da rikitarwa.
– Dole ne a riƙa sabunta bayanan da ake buƙata don tantancewa akai-akai.
5. Haɗa Hanyoyin Ganewa
A aikin asibiti, sau da yawa ana buƙatar haɗa hanyoyin ganewar asali don samun ingantaccen ganewar asali. Misali, ana iya bin diddigin ƙwayoyin cuta ta hanyar amfani da PCR don tabbatarwa, ko kuma ana iya amfani da ELISA tare da RDTs don inganta daidaiton ganewar asali.
[Wannan haɗin hanyoyin zai iya rama raunin wata hanya tare da ƙarfin wata. Haɗa hanyoyin ganewar asali daban-daban zai samar da cikakken hoto da kuma taimakawa wajen yanke shawara mafi kyau game da magani.]
