IVD reagent stability test feem ntau suav nrog lub sijhawm tiag tiag thiab muaj txiaj ntsig zoo, kev ruaj ntseg nrawm, rov ua kom ruaj khov, qauv kev ruaj ntseg, kev ruaj ntseg tsheb thauj mus los, reagent thiab qauv cia ruaj khov, thiab lwm yam.

Lub hom phiaj ntawm cov kev tshawb fawb kev ruaj ntseg no yog los txiav txim lub txee lub neej thiab kev thauj mus los thiab kev cia khoom ntawm cov khoom reagent suav nrog ua ntej qhib thiab tom qab qhib.

Tsis tas li ntawd, nws tseem tuaj yeem txheeb xyuas qhov ruaj khov ntawm cov khoom thaum lub sijhawm khaws cia thiab lub txee-lub neej hloov pauv, txhawm rau ntsuas thiab kho cov khoom lossis cov khoom ntim raws li cov txiaj ntsig.

Noj qhov ntsuas ntawm qhov tseeb thiab cov qauv cia ruaj khov ua piv txwv, qhov ntsuas no yog ib qho tseem ceeb uas cuam tshuam rau kev ua tau zoo ntawm IVD reagents.Yog li ntawd, cov reagents yuav tsum tau muab tso thiab khaws cia nyob rau hauv nruj raws li cov lus qhia.Piv txwv li, cov ntsiab lus dej thiab cov ntsiab lus oxygen nyob rau hauv qhov chaw cia ntawm cov hmoov qhuav qhuav uas muaj polypeptides muaj kev cuam tshuam zoo rau kev ruaj ntseg ntawm cov reagents.Yog li ntawd, cov hmoov qhuav qhuav uas tsis tau qhib yuav tsum tau muab cia rau hauv lub tub yees kom kaw li sai tau.

Cov qauv ua tiav los ntawm cov tsev kho mob tom qab sau tseg yuav tsum muab khaws cia raws li qhov xav tau raws li lawv qhov kev ua tau zoo thiab kev pheej hmoo coefficient.Rau kev kuaj ntshav niaj hnub, tso cov qauv ntshav ntxiv nrog cov tshuaj tiv thaiv coagulant ntawm chav tsev kub (kwv yees li 20 ℃) ​​rau 30 feeb, 3 teev, thiab 6 teev rau kev kuaj.Rau qee cov qauv tshwj xeeb, xws li nasopharyngeal swab cov qauv sau thaum kuaj nucleic acid ntawm COVID-19, yuav tsum tau siv cov qauv kuaj kab mob uas muaj cov tshuaj tiv thaiv kab mob, thaum cov qauv siv rau kev cais tus kab mob thiab kuaj nucleic acid yuav tsum tau sim sai li sai tau. , thiab cov qauv uas tuaj yeem kuaj tau hauv 24 teev tuaj yeem khaws cia ntawm 4 ℃;Cov qauv uas tsis tuaj yeem kuaj tsis pub dhau 24 teev yuav tsum khaws cia ntawm - 70 ℃ lossis qis dua (yog tias tsis muaj - 70 ℃ cia txias, lawv yuav tsum tau khaws cia ib ntus hauv - 20 ℃ tub yees).
