Uvavanyo lozinzo lwe-reagent ye-IVD luhlala lubandakanya uzinzo lwexesha langempela nolusebenzayo, uzinzo olukhawulezileyo, uzinzo lokuchithwa kwakhona, uzinzo lwesampulu, uzinzo lokuthuthwa, uzinzo lwe-reagent kunye nozinzo lokugcina isampuli, njl.

Injongo yezi zifundo zozinzo kukufumanisa ixesha elichithwe kwishelufu kunye neemeko zokuthuthwa kunye nokugcinwa kweemveliso ze-reagent kuquka ngaphambi kokuvulwa nasemva kokuvulwa.

Ukongeza, inokuqinisekisa uzinzo lwemveliso xa iimeko zokugcina kunye nexesha lokuphelelwa kwayo zitshintsha, ukuvavanya nokulungisa imveliso okanye izinto zephakheji ngokweziphumo.

Ukuthatha umzekelo wesalathisi sozinzo lokugcinwa kwangempela kunye nesampulu, olu luhlu lolunye lwezinto ezibalulekileyo ezichaphazela ukusebenza kakuhle kwee-reagents ze-IVD. Ke ngoko, ii-reagents kufuneka zibekwe kwaye zigcinwe ngokuhambelana nemiyalelo. Umzekelo, umxholo wamanzi kunye nomxholo weoksijini kwindawo yokugcina ii-reagents zepowder ezomisiweyo ezifakwe ii-polypeptides zinefuthe elikhulu ekuzinzeni kwee-reagents. Ke ngoko, umgubo ongavulwanga owomisiweyo kufuneka ugcinwe efrijini uvaliwe kangangoko.

Iisampulu ezicutshungulwa zizikhungo zonyango emva kokuqokelelwa kufuneka zigcinwe njengoko kufuneka ngokokusebenza kwazo kunye nomlinganiselo womngcipheko. Uvavanyo lwegazi oluqhelekileyo, Beka isampulu yegazi eyongeziweyo kunye ne-anticoagulant kubushushu begumbi (malunga ne-20 ℃) ​​imizuzu engama-30, iiyure ezi-3, kunye neeyure ezi-6 zovavanyo. Kwiisampulu ezithile ezikhethekileyo, ezifana neesampulu ze-nasopharyngeal swab eziqokelelwe ngexesha lovavanyo lwe-nucleic acid ye-COVID-19, kufuneka kusetyenziswe ityhubhu yokuvavanya intsholongwane equlethe isisombululo sokugcina intsholongwane, ngelixa iisampulu ezisetyenziselwa ukwahlukanisa intsholongwane kunye nokufunyanwa kwe-nucleic acid kufuneka zivavanywe ngokukhawuleza, kwaye iisampulu ezinokuvavanywa kwiiyure ezingama-24 zinokugcinwa kwi-4 ℃; Iisampulu ezingenakuvavanywa kwiiyure ezingama-24 kufuneka zigcinwe kwi- -70 ℃ okanye ngaphantsi (ukuba akukho meko yokugcina i- -70 ℃, kufuneka zigcinwe okwethutyana kwifriji ye- -20 ℃).
