Kuyerekeza kwa njira ziwiri zozindikirira ma antibodies a SARS-CoV-2 receptor binding domain IgG antibody ngati cholembera pakuwunika ma antibodies omwe ali ndi kachilombo ka COVID-19.

Int J Infect Dis.Juni 20, 2021: S1201-9712(21)00520-8.doi: 10.1016/j.ijid.2021.06.031.Pa intaneti musanasindikize.
Zoyambira: Neutralizing antibodies (NAbs) ndizofunikira kupewa kufalikiranso ndi COVID-19.Tinayerekezera mayesero awiri okhudzana ndi NAb, omwe ndi hemagglutination test (HAT) ndi testrement virus neutralization test (sVNT).
Njira: Zodziwika bwino za HAT zinali kufaniziridwa ndi sVNT, ndipo kukhudzidwa ndi kukhazikika kwa ma antibodies kwa odwala omwe ali ndi vuto la matenda osiyanasiyana adayesedwa mu gulu la odwala 71 pa 4 kwa masabata a 6 ndi 13 kwa masabata a 16.The kinetic kuwunika kwa odwala pachimake matenda osiyanasiyana chowawa anachitidwa mu woyamba, wachiwiri ndi wachitatu milungu.
Zotsatira: Zodziwika bwino za HAT ndi> 99%, ndipo mphamvu zake zimakhala zofanana ndi za sVNT, koma zotsika kuposa za sVNT.Mlingo wa HAT umagwirizana kwambiri ndi mlingo wa sVNT (Spearman's r = 0.78, p<0.0001).Poyerekeza ndi odwala omwe ali ndi matenda ochepa, odwala omwe ali ndi matenda apakati komanso oopsa amakhala ndi ma HAT titers.Odwala 6/7 odwala kwambiri anali ndi titer ya> 1:640 sabata yachiwiri yoyambira, pomwe odwala 5/31 okha omwe anali ndi vuto lochepa kwambiri anali ndi titer ya> 1: 160 sabata yachiwiri yoyambira.
Kutsiliza: Popeza HAT ndi njira yosavuta komanso yotsika mtengo kwambiri yodziwira, ndi yabwino ngati chizindikiro cha NAb m'madera osauka.
