Mayeso okhazikika a reagent a IVD nthawi zambiri amakhala ndi kukhazikika kwa nthawi yeniyeni komanso kogwira mtima, kukhazikika kofulumira, kukhazikika kwa kusungunuka, kukhazikika kwa zitsanzo, kukhazikika kwa mayendedwe, kukhazikika kwa reagent ndi kusungira zitsanzo, ndi zina zotero.

Cholinga cha maphunziro okhazikika awa ndi kudziwa nthawi yosungiramo zinthu ndi momwe zinthu zosungiramo zinthu zogwiritsidwa ntchito zimayendera komanso momwe zinthuzo zimasungidwira.

Kuphatikiza apo, ikhozanso kutsimikizira kukhazikika kwa chinthucho pamene zinthu zosungidwa ndi nthawi yosungiramo zinthu zikusintha, kuti iwunikenso ndikusintha zinthuzo kapena phukusi lake malinga ndi zotsatira zake.

Potengera chitsanzo cha kukhazikika kwenikweni ndi chitsanzo cha kusungirako, chizindikirochi ndi chimodzi mwazinthu zofunika kwambiri zomwe zimakhudza kugwira ntchito kwa ma IVD reagents. Chifukwa chake, ma reagents ayenera kuyikidwa ndikusungidwa motsatira malangizo. Mwachitsanzo, kuchuluka kwa madzi ndi mpweya m'malo osungira ma reagents a ufa wouma wozizira okhala ndi ma polypeptides zimakhudza kwambiri kukhazikika kwa ma reagents. Chifukwa chake, ufa wouma wouma wosatsegulidwa uyenera kusungidwa mufiriji motsekedwa momwe zingathere.

Zitsanzo zomwe zakonzedwa ndi mabungwe azachipatala zitatengedwa ziyenera kusungidwa monga momwe zimafunikira malinga ndi momwe zimagwirira ntchito komanso kuchuluka kwa chiopsezo. Pakuwunika magazi nthawi zonse, ikani chitsanzo cha magazicho ndi anticoagulant kutentha kwa chipinda (pafupifupi 20 ℃) ​​kwa mphindi 30, maola 3, ndi maola 6 kuti muyesedwe. Pa zitsanzo zina zapadera, monga zitsanzo za nasopharyngeal swab zomwe zasonkhanitsidwa panthawi yoyesa nucleic acid ya COVID-19, muyenera kugwiritsa ntchito chubu choyezera kachilombo chomwe chili ndi yankho losungira kachilombo, pomwe zitsanzo zomwe zimagwiritsidwa ntchito popatula kachilombo ndi kuzindikira nucleic acid ziyenera kuyesedwa mwachangu momwe zingathere, ndipo zitsanzo zomwe zingayesedwe mkati mwa maola 24 zitha kusungidwa pa 4 ℃; Zitsanzo zomwe sizingayesedwe mkati mwa maola 24 ziyenera kusungidwa pa -70 ℃ kapena pansi (ngati palibe -70 ℃ momwe zimasungidwira, ziyenera kusungidwa kwakanthawi mufiriji ya -20 ℃).
