Cov khoom no tsim nyog rau kev kuaj pom zoo ntawm COVID-19.Nws muab kev pabcuam hauv kev kuaj mob ntawm tus kabmob tshiab tshiab.
TSEEM CEEB
Cov kab mob tshiab coronaviruses muaj nyob rau β genus.COVID-19 yog tus kab mob ua pa hnyav heev.Tib neeg feem ntau raug mob.Tam sim no, cov neeg mob kis los ntawm tus kabmob tshiab no yog qhov tseem ceeb ntawm kev kis tus kabmob;Cov neeg mob asymptomatic kuj tuaj yeem yog qhov kis tau.Raws li kev tshawb nrhiav kev kis kabmob tam sim no, lub sijhawm incubation yog 1 txog 14 hnub, feem ntau yog 3 txog 7 hnub.Cov tsos mob tseem ceeb muaj xws li kub taub hau, qaug zog thiab hnoos qhuav.Qhov ntswg congestion, los ntswg qhov ntswg, mob caj pas, myalgia thiab raws plab yog pom nyob rau hauv ob peb kis.
PRINCIPLE
Cov khoom siv kuaj muaj ob daim ntawv xeem:
Nyob rau hauv ib tug ntawm lawv, ib tug burgundy coloured conjugate ncoo uas muaj Novel coronavirus recombinant hnab ntawv antigens conjugated nrog Colloid kub (Novel coronavirus conjugates), 2) ib tug nitrocellulose membrane strip muaj ob kab xeem (IgG thiab IgM kab) thiab ib tug tswj kab (C1 kab) .
IgM kab yog pre-coated nrog nas antihuman IgM antibody, IgG kab yog coated nrog nas anti-Human IgG antibody.Thaum lub ntim txaus ntawm cov qauv kuaj tau muab xa mus rau hauv cov qauv zoo ntawm cov cuab yeej kuaj, cov qauv txav los ntawm kev ua haujlwm capillary thoob plaws lub cuab yeej.IgM anti-Novel coronavirus, yog tias muaj nyob hauv cov qauv, yuav khi rau Novel coronavirus conjugates.
Lub immunocomplex yog tom qab ntawd raug ntes los ntawm cov tshuaj reagent pre-coated ntawm IgM band, tsim cov kab burgundy xim IgM, qhia txog Novel coronavirus IgM qhov txiaj ntsig zoo.IgG anti-Novel coronavirus yog muaj nyob rau hauv cov qauv yuav khi rau Novel coronavirus conjugates.Lub immunocomplex yog tom qab ntawd raug ntes los ntawm cov tshuaj reagent coated ntawm kab IgG, tsim cov xim burgundy IgG kab, qhia txog Novel coronavirus IgG qhov kev kuaj pom zoo.Tsis muaj ib kab T (IgG thiab IgM) qhia tias qhov tshwm sim tsis zoo.Txhawm rau ua raws li kev tswj hwm txheej txheem, cov kab xim xim yuav ib txwm tshwm sim ntawm thaj chaw tswj kab uas qhia tias qhov ntim ntawm cov qauv tau muab ntxiv thiab daim nyias nyias tau tshwm sim.
Hauv lwm cov sawb, qhov kev sim strip yog tsim los ntawm cov hauv qab no: piv txwv li ncoo, reagent ncoo, cov tshuaj tiv thaiv membrane, thiab absorbing ncoo.Lub reagent ncoo muaj cov colloidal-kub conjugated nrog cov monoclonal antibodies tawm tsam cov protein nucleocapsid ntawm SARS-CoV-2;cov tshuaj tiv thaiv membrane muaj cov tshuaj tiv thaiv thib ob rau nucleocapsid protein ntawm SARS-CoV-2.Tag nrho cov kab nrib pleb yog tsau hauv cov khoom siv yas.Thaum cov qauv ntxiv rau hauv cov qauv zoo, conjugates qhuav nyob rau hauv lub reagent ncoo yog yaj thiab migrate nrog rau cov qauv.Yog tias SARS-CoV-2 antigen tshwm sim hauv cov qauv, ib qho nyuaj tsim ntawm cov tshuaj tiv thaiv-SARS-2 conjugate thiab tus kab mob yuav raug ntes los ntawm cov tshuaj tiv thaiv tshwj xeeb ntawm SARS-2 monoclonal antibodies coated ntawm thaj tsam kab mob (T).Kev tsis muaj T kab qhia pom qhov tshwm sim tsis zoo.Txhawm rau ua tus txheej txheem tswj hwm txoj kab liab yuav ib txwm tshwm sim hauv cheeb tsam tswj kab (C2) qhia tias qhov ntim ntawm cov qauv raug muab ntxiv thiab daim nyias nyias tau tshwm sim.
