Ukuhlolwa kokuqina kwe-reagent ye-IVD kuvame ukufaka ukuzinza kwesikhathi sangempela nokusebenzayo, ukuzinza okusheshayo, ukuzinza kokuqedwa kabusha, ukuzinza kwesampula, ukuzinza kwezokuthutha, ukuzinza kwe-reagent kanye nokugcinwa kwesampula, njll.

Inhloso yalezi zifundo zokuzinza ukunquma isikhathi sokuphelelwa yisikhathi kanye nezimo zokuthuthwa nokugcinwa kwemikhiqizo ye-reagent okuhlanganisa ngaphambi kokuvulwa nangemva kokuvulwa.

Ngaphezu kwalokho, ingaqinisekisa futhi ukuzinza komkhiqizo lapho izimo zokugcina kanye nesikhathi sokuphila kweshelufu kushintsha, ukuhlola nokulungisa umkhiqizo noma izinto zephakheji ngokwemiphumela.

Uma sithatha inkomba yokuqina kwangempela kanye nokwesampula njengesibonelo, le nkomba ingenye yezinto ezibalulekile ezithinta ukusebenza kahle kwama-reagent e-IVD. Ngakho-ke, ama-reagent kufanele abekwe futhi agcinwe ngokuhambisana nemiyalelo. Isibonelo, okuqukethwe kwamanzi kanye nokuqukethwe komoya-mpilo endaweni yokugcina ama-reagent empuphu eyomisiwe eqandisiwe aqukethe ama-polypeptide kunomthelela omkhulu ekuqineni kwama-reagent. Ngakho-ke, impuphu eyomisiwe eqandisiwe engavulwanga kufanele igcinwe esiqandisini ivaliwe ngangokunokwenzeka.

Amasampula acutshungulwa yizikhungo zezokwelapha ngemuva kokuqoqwa kufanele agcinwe njengoba kudingeka ngokuya ngokusebenza kwawo kanye ne-coefficient yengozi. Ukuze kuhlolwe igazi njalo, Beka isampula yegazi engezwe ne-anticoagulant ekushiseni kwegumbi (cishe ama-20 ℃) ​​imizuzu engama-30, amahora ama-3, namahora ayi-6 ukuze kuhlolwe. Ukuze uthole amasampula akhethekile, njengesampula ye-nasopharyngeal swab eqoqwe ngesikhathi sokuhlolwa kwe-nucleic acid ye-COVID-19, kudingeka usebenzise ithubhu lokuhlola igciwane eliqukethe isisombululo sokugcina igciwane, kuyilapho amasampula asetshenziselwa ukuhlukaniswa kwegciwane kanye nokutholwa kwe-nucleic acid kufanele ahlolwe ngokushesha okukhulu, kanti amasampula angahlolwa zingakapheli amahora angama-24 angagcinwa ku-4 ℃; Amasampula angenakuhlolwa zingakapheli amahora angama-24 kufanele agcinwe ku--70 ℃ noma ngaphansi (uma kungekho simo sokugcina --70 ℃, kufanele agcinwe okwesikhashana esiqandisini --20 ℃).
