Mayeso okhazikika a IVD reagent nthawi zambiri amaphatikiza kukhazikika kwanthawi yeniyeni komanso kogwira mtima, kukhazikika kwachangu, kukhazikika kwakusungunuka, kukhazikika kwa zitsanzo, kukhazikika kwamayendedwe, reagent ndi kukhazikika kosungirako zitsanzo, ndi zina zambiri.

Cholinga cha maphunziro okhazikikawa ndikuzindikira nthawi ya alumali komanso momwe amayendera ndi kusungirako zinthu za reagent kuphatikiza musanatsegule komanso mutatsegula.

Kuonjezera apo, ikhoza kutsimikiziranso kukhazikika kwa mankhwala pamene zinthu zosungiramo zinthu zosungiramo zinthu komanso moyo wa alumali zikusintha, kuyesa ndi kusintha zinthu zomwe zimagwiritsidwa ntchito kapena phukusi malinga ndi zotsatira zake.

Kutengera kukhazikika kwenikweni ndi zitsanzo zosungirako monga chitsanzo, index iyi ndi imodzi mwazinthu zofunika kwambiri zomwe zimakhudza mphamvu ya ma reagents a IVD.Choncho, ma reagents ayenera kuikidwa ndi kusungidwa mogwirizana ndi malangizo.Mwachitsanzo, madzi okhutira ndi okosijeni mu malo osungiramo amaundana-zouma ufa reagents muna polypeptides zimakhudza kwambiri kukhazikika kwa reagents.Choncho, ufa wosatsegula-wouma wowuma uyenera kusungidwa mufiriji ngati kutsekedwa momwe zingathere.

Zitsanzo zomwe zakonzedwa ndi mabungwe azachipatala pambuyo pa kusonkhanitsa zidzasungidwa monga momwe zimafunira malinga ndi momwe amachitira komanso chiopsezo chawo.Kuti mufufuze magazi nthawi zonse, ikani magazi omwe aikidwa ndi anticoagulant kutentha kwapakati (pafupifupi 20 ℃) ​​kwa mphindi 30, maola atatu, ndi maola 6 kuti ayezedwe.Pazitsanzo zina zapadera, monga zitsanzo za nasopharyngeal swab zomwe zimasonkhanitsidwa pakuyesa kwa nucleic acid ya COVID-19, zimayenera kugwiritsa ntchito chubu chotengera ma virus chomwe chili ndi njira yosungira ma virus, pomwe zitsanzo zomwe zimagwiritsidwa ntchito pakudzipatula kwa ma virus komanso kuzindikira kwa nucleic acid ziyenera kuyesedwa posachedwa. , ndi zitsanzo zomwe zikhoza kuyesedwa mkati mwa maola 24 zikhoza kusungidwa pa 4 ℃;Zitsanzo zomwe sizingayesedwe mkati mwa maola 24 ziyenera kusungidwa pa - 70 ℃ kapena pansi (ngati palibe - 70 ℃ yosungirako, ziyenera kusungidwa kwakanthawi mufiriji - 20 ℃).
