Kuyedzwa kwekugadzikana kweIVD reagent kunowanzo sanganisira kugadzikana kwenguva chaiyo uye kunoshanda, kugadzikana nekukurumidza, kugadzikana kwekunyungudika, kugadzikana kwemuenzaniso, kugadzikana kwekufambisa, kugadzikana kwekuchengetedza reagent uye sampuro, nezvimwewo.

Chinangwa chezvidzidzo izvi zvekugadzikana ndechekuona nguva yekushanda uye mamiriro ekutakurwa uye kuchengetwa kwezvinhu zvinogadzirisa reagent kusanganisira zvisati zvavhurwa uye mushure mekuvhurwa.

Pamusoro pezvo, inogonawo kusimbisa kugadzikana kwechigadzirwa kana mamiriro ekuchengetera uye nguva yekuchengetera zvinhu zvichichinja, kuongorora nekugadzirisa zvigadzirwa kana zvinhu zvepakeji zvichienderana nemigumisiro.

Tichitora muenzaniso wekuchengetedza kwakasimba uye kwemuenzaniso, iyi index ndeimwe yezvinhu zvakakosha zvinokanganisa kushanda kweIVD reagents. Nokudaro, ma reagents anofanirwa kuiswa uye kuchengetwa zvichienderana nemirairo. Semuenzaniso, huwandu hwemvura uye huwandu hweokisijeni munzvimbo yekuchengetera ma reagents eupfu hwakaomeswa nechando ane polypeptides zvine simba guru pakugadzikana kwe reagents. Nokudaro, upfu hwakaomeswa nechando husina kuvhurwa hunofanira kuchengetwa mufiriji hwakavharwa sezvinobvira.

Mienzaniso inogadziriswa nezvipatara mushure mekutorwa inofanira kuchengetwa sezvinodiwa zvichienderana nekushanda kwayo uye huwandu hwenjodzi. Pakuongororwa ropa nguva dzose, isa sampuro yeropa yakawedzerwa neanticoagulant patembiricha yemukamuri (inenge 20 ℃) ​​kwemaminitsi makumi matatu, maawa matatu, uye maawa matanhatu kuti iongororwe. Kune mimwe sampuli yakakosha, senge nasopharyngeal swab sampuro dzakaunganidzwa panguva yekuyedzwa kweCOVID-19 ne nucleic acid, unofanirwa kushandisa chubhu yesampuro yehutachiona ine mushonga wekuchengetedza hutachiona, nepo sampuli dzinoshandiswa pakupatsanurwa kwehutachiona uye kuonekwa kwe nucleic acid dzinofanira kuongororwa nekukurumidza sezvinobvira, uye sampuli dzinogona kuongororwa mukati memaawa makumi maviri nemana dzinogona kuchengetwa pa4 ℃; Mienzaniso isingakwanise kuongororwa mukati memaawa makumi maviri nemana inofanira kuchengetwa pa -70 ℃ kana pasi (kana pasina mamiriro ekuchengetwa kwe -70 ℃, inofanira kuchengetwa kwenguva pfupi mufiriji ye -20 ℃).
