Sensitivity and Specificity: The 2019-nCOV/COVID-19 IgG/IgM Rapid Test Device tau raug muab piv rau ib qho kev ua lag luam RT-PCR kev sim siv cov qauv kuaj mob.Cov txiaj ntsig tau pom tias 2019-nCoV/COVID-19 IgG/IgM Rapid Tests Devices muaj qhov tshwj xeeb thiab muaj peev xwm.

Rau kev kuaj IgG:

Tus txheeb ze rhiab heev: 233/268 = 86.94% (95% CI *: 82.35% - 90.49%)

Tus txheeb ze Specificity: 287/289 = 99.31% (95% CI *: 97.52% - 99.92%)

Qhov tseeb: 520/557 = 93.36% (95% CI *: 90.96% - 95.16%)

* Kev ntseeg siab luv

Rau kev kuaj IgM

Tus txheeb ze rhiab heev: 223/268 = 83.21% (95% CI *: 78.19% - 87.48%)

Tus txheeb ze Specificity: 282/289 = 97.58% (95% CI *: 95.07% - 99.02%)

Qhov tseeb: 505/557 = 90.66% (95% CI *: 87.94% - 92.95%)

* Kev ntseeg siab luv

TSEEM CEEB: Cov khoom siv no siv immunochromatography.Daim ntawv xeem muaj: 1) colloidal kub - labeled recombinant tshiab coronavirus antigen thiab zoo tswj antibody kub cim; 2) ob kab kuaj pom (IgG thiab IgM kab) thiab ib tug zoo Control kab (C kab) ntawm nitrocellulose membrane.Cov IgM kab yog immobilized nrog ib tug monocrystalline antibody - IgM tshuaj tiv thaiv kab mob; kab IgG yog immobilized nrog reagent rau kev kuaj pom tus kabmob tshiab IgG antibody; thiab C kab yog immobilized nrog ib tug zoo tswj antibody.Thaum ib tug tsim nyog tus nqi ntawm cov qauv kuaj tau ntxiv rau cov qauv qhov ntawm daim ntawv xeem, cov qauv yuav mus rau pem hauv ntej raws li daim ntawv xeem nyob rau hauv qhov kev txiav txim ntawm lub capillary.Yog hais tias tus qauv muaj ib tug IgM antibody, cov tshuaj tiv thaiv yuav khi rau lub colloidal kub - sau npe tshiab coronavirus antigen. Lub cev tiv thaiv kab mob yuav raug ntes los ntawm cov tshuaj tiv thaiv - tib neeg IgM tshuaj tiv thaiv kab mob immobilized rau ntawm daim nyias nyias los ua cov ntshav - liab IgM kab, qhia tias tus kab mob tshiab coronavirus IgM antibody yog qhov zoo.Yog tias cov qauv muaj cov tshuaj tiv thaiv IgG, cov tshuaj tiv thaiv yuav khi rau colloidal kub - sau npe tshiabcoronavirus antigen, thiab cov tshuaj tiv thaiv kab mob los ntawm daim nyias nyias yuav ua rau lub cev tiv thaiv kab mob. ntshav - liab IgG kab, qhia tias tus kab mob tshiab coronavirus IgG antibody yog qhov zoo.Yog tias qhov kev sim IgG thiab IgM kab tsis muaj xim, cov txiaj ntsig tsis zoo yog tshwm sim. Daim ntawv xeem kuj tseem muaj cov kab tswj zoo C.Cov fuchsia zoo tswj kab C yuav tsum tshwm sim tsis hais seb kab ntsuas zoo li cas. Cov kab tswj tau zoo yog xim xim ntawm kev tswj cov tshuaj tiv thaiv kab mob zoo. Yog tias cov kab tswj kev ua tau zoo C tsis tshwm sim, cov txiaj ntsig kev xeem tsis raug, thiab cov qauv yuav tsum tau sim dua nrog lwm daim ntawv xeem.

Nov yog yam koj yuav tsum tau ua los ua qhov kev xeem:

1.Cua tus ntiv tes nrog dej cawv swab.

2.Puncture tib tus ntiv tes nrog ntiv tes pricker kom tau cov ntshav kuaj.

3.Txhawm rau tso lub hau npog tig clockwise raws li cov xub ntawm lub hau.

4.Siv lub dropper los kos cov ntshav los siv rau kev kuaj cassette.

5.Xa cov cim ntawm lub cassette tom qab 10 feeb kom pom qhov tshwm sim.

Coronavirus (CoV) belongs rau genus Nestovirus, Coronaviridae, thiab muab faib ua peb genera: α, β, thiab γ.Cov genus α thiab β tsuas yog cov kab mob rau cov tsiaj nyeg.Cov genus γ feem ntau ua rau noog kab mob.Cov kab mob kis tau los ntawm kev sib cuag ncaj qha nrog cov kua dej los yog los ntawm aerosols thiab cov tee dej. Kuj tseem muaj pov thawj tias nws tuaj yeem kis tau los ntawm fecal- qhov ncauj txoj kev.

Txog tam sim no, muaj 7 hom mob coronavirus human (HCoV) uas ua rau tib neeg cov kab mob ua pa: HCoV-229E,HCoV-OC43,SARS-CoV,HCoV-NL63,HCoV-HKU1,MERS-CoV and novel coronaviruses (2019), is an important pathogen of human respiratory infections.Among them, the novel coronavirus is founded in 2019. yog cov tsos mob xws li ua npaws thiab qaug zog, nrog rau hnoos qhuav thiab ua tsis taus pa, thiab lwm yam, uas tuaj yeem ua rau mob ntsws loj heev, ua pa tsis ua pa, thiab ua tsis taus pa hnyav. tseem muaj txoj sia - hem.

2019-nCOV/COVID-19 IgG/IgM Rapid Test Device yog cov tshuaj tiv thaiv kab mob sai sai rau kev kuaj pom zoo ntawm IgG&IgM cov tshuaj tiv thaiv kab mob Coronavirus 2019 hauv tib neeg cov ntshav, ntshav, lossis ntshav raws li kev pabcuam hauv kev kuaj mob.
