Uvavanyo lokuzinza kwe-IVD reagent luhlala lubandakanya ixesha lokwenyani kunye nozinzo olusebenzayo, uzinzo olukhawulezileyo, uzinzo lokuchithwa kwakhona, uzinzo lwesampulu, uzinzo lwezothutho, i-reagent kunye nozinzo lokugcina isampulu, njl.

Injongo yolu phando lozinzo kukumisela ubomi beshelufu kunye neemeko zothutho kunye nokugcinwa kweemveliso ze-reagent kubandakanya ngaphambi kokuvulwa nasemva kokuvulwa.

Ukongeza, inokuqinisekisa ukuzinza kwemveliso xa iimeko zokugcina kunye neshelufu-ubomi zitshintsha, ukuvavanya nokulungelelanisa imveliso okanye izinto zokupakisha ngokweziphumo.

Ukuthatha isalathiso sokuzinza kwangempela kunye nokugcinwa kwesampuli njengomzekelo, le index yenye yezinto ezibalulekileyo ezichaphazela ukusebenza kwe-IVD reagents.Ngoko ke, ii-reagents kufuneka zibekwe kwaye zigcinwe ngokuhambelana ngokungqongqo nemiyalelo.Ngokomzekelo, umxholo wamanzi kunye nomxholo we-oksijeni kwindawo yokugcina i-reagents eyomileyo ye-powder equkethe i-polypeptides inempembelelo enkulu ekuzinzeni kwee-reagents.Ngoko ke, i-powder eyomileyo engavulwanga kufuneka igcinwe efrijini njengoko ivaliwe ngokusemandleni.

Iisampuli ezicutshungulwe ngamaziko ezonyango emva kokuqokelela ziya kugcinwa njengoko zifunwa ngokuhambelana nokusebenza kwazo kunye nomngcipheko we-coefficient.Uvavanyo lwegazi lwesiqhelo, Beka isampulu yegazi eyongezwe kunye ne-anticoagulant kwiqondo lobushushu begumbi (malunga ne-20 ℃) ​​imizuzu engama-30, iiyure ezi-3, kunye neeyure ezi-6 zovavanyo.Kwezinye iisampulu ezikhethekileyo, ezinje ngeesampulu ze-nasopharyngeal swab eziqokelelwe ngexesha lovavanyo lwe-nucleic acid ye-COVID-19, kufuneka kusetyenziswe ityhubhu yesampulu yentsholongwane enesisombululo sogcino lwentsholongwane, ngelixa iisampulu ezisetyenziselwa ukwahlukaniswa kwentsholongwane kunye nokufunyanwa kwe-nucleic acid kufuneka zivavanywe ngokukhawuleza. , kunye neesampuli ezinokuvavanywa kwiiyure ezingama-24 zingagcinwa kwi-4 ℃;Iisampulu ezingenako ukuvavanywa kwiiyure ezingama-24 kufuneka zigcinwe kwi-70 ℃ okanye ngaphantsi (ukuba akukho - 70 ℃ imeko yokugcina, kufuneka zigcinwe okwethutyana kwi -20 ℃ efrijini).
