Dab tsi yog qhov txawv ntawm kev kuaj PCR thiab tshuaj ntsuam antigen? Thaum twg kuv yuav tsum xeem qhov twg?
Dab tsi yog qhov kev tshawb nrhiav
Tam sim no, PCR kuaj pom tus kab mob tshiab coronavirus yog nrhiav cov khoom siv caj ces ntawm tus kabmob tshiab los ntawm kev sim.
Qhov thim rov qab transcriptase-polymerase saw cov tshuaj tiv thaiv rov qab- muab cov kab mob RNA rau hauv DNA thiab nthuav dav cov noob caj noob ces, ua ntau txhiab daim ntawv theej kom kuaj tau qhov ntau.
Vim tias qhov kev sim no tuaj yeem nthuav dav me me ntawm cov khoom siv tshuaj tua kab mob, nws raug suav tias yog tus qauv kub thiab tuaj yeem kuaj pom tus kab mob kis tau sai dua li lwm yam kev sim xws li kev sim tshuaj antigen sai.
Hauv qhov sib piv, kev kuaj antigen sai tuaj yeem kuaj pom cov kab mob kis tau. Cov protein khi rau cov tshuaj tiv thaiv hauv cov tshuaj, thiab cov tshuaj tiv thaiv kab mob fluoresces, qhia tias muaj cov protein.
Rapid Antigen Test:
Ceev tshaj PCR (Polymerase Chain Reaction) kev sim (tsis tas yuav tos sij hawm los yog hnub rau cov txiaj ntsig hauv 15-20 feeb)
Nws tuaj yeem ua tiav hauv tsev yam tsis tas yuav tos nyob rau hauv kab rau kev sim swab, uas yog tom qab ntawd xa mus rau chav kuaj rau kev tshuaj xyuas.
Txawm li cas los xij, nws tsis yog rhiab heev li PCR (polymerase saw cov tshuaj tiv thaiv) kev tshawb nrhiav vim nws tsis tau dhau los ntawm cov noob caj noob ces.
Nws siv tau li cas?
Both tests are more accurate at detecting viral infection when the person's viral load is high, but PCR (polymerase chain reaction) tests are more sensitive than rapid antigen tests.
Ib txoj kev tshawb fawb uas muab piv rau qhov rhiab heev ntawm ob qhov kev ntsuam xyuas (kev kuaj xyuas tus kab mob no hauv cov neeg mob uas muaj COVID-19) pom tias ib hom tshuaj tiv thaiv kab mob sai sai muaj 77 feem pua ntawm cov txiaj ntsig zoo antigen piv rau PCR (polymerase saw cov tshuaj tiv thaiv) cov txiaj ntsig. Zoo ib yam.
Qhov ntawd tau nce mus rau 100 feem pua thaum kuaj hauv ib lub lis piam ntawm cov tsos mob pib.
Lub Australian Therapeutic Goods Administration (TGA) muaj ib daim ntawv teev cov tshuaj tiv thaiv sai sai uas cov neeg kuaj sim hauv ib lub lis piam ntawm cov tsos mob tshwm sim thiab nws cov txiaj ntsig tau zoo ib yam nrog kev kuaj PCR 80-95 feem pua ntawm lub sijhawm. Qee qhov kev ntsuam xyuas no raug ntsuas raws li qhov tsis txaus ntseeg, nrog 95 feem pua ntawm kev sib raug zoo nrog PCR kev xeem.
Qhov kev xeem twg yuav tsum ua? Thaum twg koj ua nws?
RT-PCR (reverse transcriptase-polymerase chain reaction) yuav tsum tau kuaj yog tias:
muaj cov tsos mob ntawm COVID-19
Paub txog kev kis tus kab mob COVID-19
Cov txiaj ntsig ntawm antigen sai sai yog qhov zoo thiab yuav tsum tau lees paub los ntawm PCR
Cov kws saib xyuas kev noj qab haus huv xav tau kev sim ua ntej tso tawm los ntawm kev cais tawm
Cov neeg saib xyuas kev noj qab haus huv xav tau kev sim ua ntej tau txais kev tso cai taug kev mus rau qhov chaw
Xav txog qhov tau txais kev kuaj antigen sai yog tias koj:
Npaj mus ntsib qhov chaw muaj kev pheej hmoo siab (xws li lub chaw saib xyuas neeg laus)
Tej zaum yuav tau ntsib nrog cov neeg muaj kev pheej hmoo kis mob (xws li cov neeg laus, lossis cov neeg tau txais kev tiv thaiv kab mob) thiab koj xav tiv thaiv lawv.
Cov tsos mob ntawm COVID-19, tab sis tsis tuaj yeem mus rau qhov chaw kuaj PCR
Koom nrog cov xwm txheej nrog coob tus neeg nyob hauv tsev, thiab kev pheej hmoo kis mob ntau dua yog tias nws yog qhov xwm txheej sab hauv tsev
Xav sim koj tus kheej sai sai rau SARS-CoV-2
Koom nrog cov phiaj xwm saib xyuas COVID tsis tu ncua (xav tau los ntawm qee qhov chaw ua haujlwm, tshwj xeeb tshaj yog cov hauv kev lag luam uas nthuav tawm cov neeg uas tsis tau txhaj tshuaj tag nrho)
Kev sim tshuaj tiv thaiv sai yog feem ntau siv los ua cov cuab yeej tshuaj ntsuam xyuas thiab tuaj yeem kuaj pom tias koj tuaj yeem muaj COVID-19, tab sis kev soj ntsuam PCR yuav tsum tau lees paub qhov kawg tshwm sim.
While a negative rapid antigen test result doesn't necessarily mean you don't have the infection, it at least protects your contacts better than no testing at all.
