Ukuhlolwa kokuzinza kwe-IVD reagent ngokuvamile kuhlanganisa ukuqina kwesikhathi sangempela nokusebenza kahle, ukuzinza okusheshisiwe, ukuzinza kokuhlakazeka kabusha, ukuqina kwesampula, ukuqina kwezokuthutha, i-reagent kanye nokuzinza kwesitoreji sesampula, njll.

Inhloso yalezi zifundo zokuzinza ukunquma impilo yeshalofu kanye nezimo zokuhamba nezokugcina zemikhiqizo ye-reagent kuhlanganise ngaphambi kokuvulwa nangemuva kokuvulwa.

Ngaphezu kwalokho, ingaphinde iqinisekise ukuqina komkhiqizo lapho izimo zokugcina nempilo yeshelufu ishintsha, ukuhlola nokulungisa umkhiqizo noma izinto zokupakisha ngokuya ngemiphumela.

Ukuthatha inkomba yokuzinza kwangempela nesampula yokugcina njengesibonelo, le nkomba ingenye yezinto ezibalulekile ezithinta ukusebenza kahle kwama-reagents e-IVD.Ngakho-ke, ama-reagents kufanele abekwe futhi agcinwe ngokuhambisana ngokuqinile nemiyalelo.Isibonelo, okuqukethwe kwamanzi nokuqukethwe kwe-oxygen endaweni yokugcina ama-reagents e-powder efriziwe aqukethe i-polypeptide kunomthelela omkhulu ekuzinzeni kwama-reagents.Ngakho-ke, i-powder efriziwe engavuliwe kufanele igcinwe esiqandisini njengoba ivaliwe ngangokunokwenzeka.

Amasampula asetshenzwe izikhungo zezokwelapha ngemva kokuqoqwa azogcinwa njengoba kudingekile ngokuya ngokusebenza kwawo kanye ne-coefficient yengozi.Ukuze uhlolwe igazi okuvamile, Beka isampula yegazi elifakwe ne-anticoagulant ekamelweni lokushisa (cishe 20 ℃) ​​imizuzu engu-30, amahora angu-3, ​​namahora angu-6 ukuze lihlolwe.Kwamanye amasampula akhethekile, njengamasampula e-nasopharyngeal swab aqoqwe ngesikhathi sokuhlolwa kwe-nucleic acid ye-COVID-19, adinga ukusebenzisa ishubhu lesampula legciwane elinesixazululo sokulondoloza igciwane, kuyilapho amasampula asetshenziselwa ukuhlukaniswa kwegciwane nokutholwa kwe-nucleic acid kufanele ahlolwe ngokushesha okukhulu. , futhi amasampula angahlolwa kungakapheli amahora angama-24 angagcinwa ku-4 ℃;Amasampula angeke ahlolwe phakathi kwamahora angama-24 kufanele agcinwe ku - 70 ℃ noma ngaphansi (uma singekho - 70 ℃ isimo sokugcina, kufanele agcinwe okwesikhashana esiqandisini - 20 ℃).
