Taw qhia
Cov kab mob coronaviruses tshiab muaj nyob rau hauv cov 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 mus rau 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.
Tus kab mob COVID-19 Antigen Rapid Test Device (Colloidal Gold) yog ib qho tshuaj tiv thaiv kab mob sai sai rau qhov muaj txiaj ntsig zoo, kev kuaj pom tus kab mob COVID-19 antigens los ntawm caj pas swab, nasopharyngeal swab thiab nasal swab specimens. Qhov kev sim no yog npaj los siv los ua ib qho kev pab hauv kev kuaj mob sai sai ntawm tus kab mob COVID-19 tus kab mob.
Test Principple
Hauv COVID-19 antigen ceev kuaj, daim nyias nyias yog pre-coated nrog anti-COVID-19 cov tshuaj tiv thaiv ntawm thaj tsam kab ntawm qhov ntsuas. Thaum lub sij hawm sim, cov qauv diluted reacts nrog cov particle coated nrog anti-COVID-19 antibodies. Qhov sib xyaw ua ke nce mus rau ntawm daim nyias nyias los ntawm kev ua haujlwm capillary kom hnov mob nrog tiv thaiv COVID-19 cov tshuaj tiv thaiv ntawm daim nyias nyias thiab tsim cov kab xim. Lub xub ntiag ntawm cov kab xim no hauv cheeb tsam xeem qhia tau tias muaj txiaj ntsig zoo, thaum nws qhov tsis tuaj yeem qhia qhov tsis zoo. Txhawm rau ua raws li cov txheej txheem tswj hwm, cov kab xim xim yuav ib txwm tshwm sim hauv cheeb tsam tswj kab uas qhia tau hais tias qhov ntim ntawm cov qauv raug ntxiv thiab daim nyias nyias wicking tau tshwm sim.
Daim duab duab
Raws li pom nyob rau hauv daim duab 1 saum toj no, cov qauv (A) migrates ntawm capillary nkaus nyob rau hauv daim nyias nyias los teb rau cov xim conjugate (B). KEVID-19 cov tshuaj tiv thaiv kab mob muaj nyob rau hauv cov qauv khi rau qhov sib txuas, tsim cov xim antibody-antigen complex (C). COVID-19 cov tshuaj tiv thaiv kab mob immobilized nyob rau hauv cheeb tsam kuaj kab ntawm daim nyias nyias captures lub complex. Kev tsim cov kab liab pom pom tau zoo (D). Qhov tsis muaj kab liab tsim nyob rau hauv cheeb tsam xeem kab qhia tau hais tias tsis zoo. Nyob rau hauv cheeb tsam tswj kab ntawm daim nyias nyias, immobilized reagents ntes cov xim conjugate tsis hais cov qauv kuaj muaj pes tsawg leeg. Qhov tshwm sim pom kab liab (E) lees paub tias qhov kev ntsuam xyuas ua haujlwm raug.
Covid-19 cov tshuaj tiv thaiv sai npaum li cas?

rhiab heev
COVID-19 Antigen Rapid Test Device muaj tag nrho rhiab heev ntawm kwv yees li 96.67 feem pua, uas txhais tau hais tias lawv tau ntes kwv yees li 96 feem pua ntawm cov neeg uas muaj tus kab mob no thiab ploj tsuas yog 4 feem pua.
Qhov tshwj xeeb
Qhov zoo tsis tseeb yog thaum koj kuaj qhov zoo rau COVID-19 thaum koj tsis muaj nws tiag. COVID-19 Antigen Rapid Test Device tsis tshua muaj qhov tshwm sim tsis tseeb.
Vim li cas COVID-19 kev kuaj sai thiaj raug siv?
Txawm hais tias muaj feem ntau ntawm qhov tau txais cov txiaj ntsig tsis zoo, COVID-19 cov kev sim sai sai muab ntau yam txiaj ntsig ntawm kev kuaj PCR.
Kev ntsuam xyuas ceev:
● tuaj yeem muab cov txiaj ntsig tsis pub dhau 15 feeb tsis yog hnub
● portable thiab nkag tau yooj yim dua li kev kuaj PCR
● tsis tshua kim dua li kev kuaj PCR
● tsis tas yuav muaj chav kuaj lossis cov cuab yeej kuaj tshwj xeeb
