Qhov sib txawv tseem ceeb ntawm kev kuaj molecular thiab antigen yog qhov kev sim molecular kuaj pom qee qhov ntawm cov khoom siv caj ces ntawm cov kab mob thaum kuaj antigen pom cov cim tshwj xeeb hu ua antigens tam sim no ntawm cov kab mob.
Kev kuaj Molecular thiab kuaj antigen yog ob hom kev kuaj mob uas siv los kuaj xyuas cov kab mob nquag xws li tus kab mob SARS-CoV-2. Molecular tests tsom cov ntaub ntawv genomic tshwj xeeb rau cov kab mob lossis cov kab mob sib kis. Lawv ua kom cov kab mob tshwj xeeb ntawm cov khoom siv caj ces ntawm cov kab mob. Yog li, lawv yog cov txheej txheem molecular xws li PCR, LAMP, thiab CRISPR. Kev ntsuam xyuas antigen, ntawm qhov tod tes, tsom cov cim protein nyob rau sab nraud ntawm cov kab mob. Kev kuaj molecular rau SARS-CoV-2 kuaj pom qhov tshwj xeeb ntawm SARS-CoV-2 genome sequence, thaum kuaj antigen rau SARS-CoV-2 kuaj pom cov cim tshwj xeeb ntawm sab nraud ntawm tus kab mob SARS-CoV-2.
Kev Ntsuas Molecular yog dab tsi?
Kev kuaj molecular yog hom kev kuaj mob uas siv los kuaj pom tus kab mob. Kev ntsuam xyuas molecular yog ua raws li cov txheej txheem molecular, thiab lawv kuaj xyuas qhov tshwj xeeb lossis cov kab ke ntawm cov khoom siv caj ces ntawm cov kab mob. Lawv tseem hu ua nucleic acid amplification tests. Cov kab mob tshwj xeeb genomic ib ntus txheeb xyuas qhov muaj tus kab mob tshwj xeeb ntawm tus kab mob. Piv txwv li, SARS-CoV-2 yog ib leeg-stranded positive-sense RNA virus. RNA ntawm tus kab mob yuav ua kom nthuav dav los ntawm kev sim molecular. Yog tias muaj tus kab mob nyob hauv cov qauv, nws yuav nthuav dav thiab kuaj pom thaum kawg, lees paub tias muaj tus kab mob. Yog tias tam sim no, qhov kev kuaj pom zoo. Yog tias tsis kuaj pom RNA, qhov kev sim tsis zoo.
Daim duab 01: Kev Ntsuas Molecular
Feem ntau, cov kev ntsuam xyuas molecular tsim ntau lab luam tawm los ntawm ib ntu me ntawm genome. Yog li ntawd, txawm tias muaj tus kab mob me me, nws tuaj yeem kuaj pom los ntawm kev ntsuas molecular. Yog li ntawd, kev ntsuam xyuas molecular yog qhov tseeb thiab muaj kev nkag siab zoo. Polymerase chain reaction (PCR) tests, loop-mediated isothermal amplification (LAMP), thiab clustered, tsis tu ncua interspaced luv palindromic repeat (CRISPR)-raws li kev ntsuam xyuas yog ob peb hom kev ntsuam xyuas molecular.
Kev kuaj Antigen yog dab tsi?
Antigen test yog lwm qhov kev kuaj mob. Nws pom cov cim tshwj xeeb ntawm cov kab mob ntawm cov kab mob. Nws yog ib qho kev sim ceev thiab muab cov txiaj ntsig sai dua li qhov ntsuas molecular. Nws yuav siv sij hawm 30 feeb rau hnub, nyob ntawm qhov kev xeem. Tsis zoo li kev sim tshuaj molecular, kev kuaj tshuaj antigen tuaj yeem ua tau ntawm qhov chaw kho mob, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kho mob. Txawm li cas los xij, nyob rau hauv kev sib piv rau kev kuaj molecular, kev kuaj antigen muaj feem ntau dua ntawm kev ploj ntawm kev kis kab mob. Txawm hais tias qhov kev ntsuam xyuas antigen tsis zoo, qhia tias tsis muaj tus kab mob nquag, kev sim tshuaj molecular yog qhov tsim nyog los xyuas qhov tshwm sim.
Daim duab 02: Kev Ntsuas Antigen Rapid
Rapid antigen test yog cov tshuaj tiv thaiv kab mob uas feem ntau yog siv rau SARS-CoV-2 tam sim no hauv ntiaj teb. Nws kuaj pom tus kab mob SARS-CoV-2 saum npoo ntawm tus kab mob sab nraud. Txawm li cas los xij, nws tsuas yog kuaj pom qhov ua haujlwm ntawm cov kab mob sib kis. Yog tias cov protein ntau lawm tsawg, nws yuav ua rau qhov tshwm sim tsis tseeb lossis tsis zoo.
Dab tsi yog qhov zoo sib xws ntawm Molecular thiab Antigen Test?
- Kev kuaj Molecular thiab antigen yog kev kuaj mob.
- Lawv xav tau tus qauv los ntawm tus neeg mob.
Qhov txawv ntawm Molecular thiab Antigen Test yog dab tsi?
Kev kuaj molecular yog kev kuaj mob uas kuaj pom cov kab mob tshwj xeeb ntawm cov khoom siv caj ces ntawm tus neeg kis tus kab mob, thaum kuaj antigen yog kev kuaj mob uas kuaj pom cov cim protein tshwj xeeb pom sab nraum cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev kuaj molecular thiab antigen. Tsis tas li ntawd, qhov kev ntsuam xyuas molecular yuav siv sij hawm 1 mus rau ntau hnub los muab cov txiaj ntsig, thaum qhov kev kuaj antigen tuaj yeem tsim cov txiaj ntsig li ntawm 30 feeb. Yog li, qhov no yog lwm qhov sib txawv ntawm molecular thiab antigen test.
Ntxiv mus, qhov kev sim molecular yog qhov rhiab heev dua li kev kuaj antigen. Qhov tseem ceeb tshaj plaws, yuav tsum tau kuaj cov tshuaj molecular hauv qhov chaw kuaj mob, thaum kuaj cov tshuaj tiv thaiv kab mob tuaj yeem ua tau hauv qhov chaw kho mob, txawm tias nyob ntawm qhov chaw saib xyuas.
Cov ntawv qhia hauv qab no qhia ntau qhov sib txawv ntawm qhov ntsuas molecular thiab antigen hauv daim ntawv teev npe.
Summary – Molecular vs Antigen Test
Kev kuaj molecular kuaj pom cov khoom siv caj ces ntawm cov kab mob thaum kuaj antigen pom cov cim tshwj xeeb ntawm cov protein nyob rau saum npoo ntawm cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm kev kuaj molecular thiab antigen. Ib qho kev kuaj antigen muab cov txiaj ntsig sai dua li qhov ntsuas molecular. Tab sis, cov txiaj ntsig ntawm kev ntsuas molecular yog qhov tseeb thiab rhiab dua li cov txiaj ntsig ntawm kev kuaj antigen. Kev kuaj Antigen tuaj yeem tsim cov txiaj ntsig tsis tseeb lossis tsis zoo yog tias cov kab mob kis tau tsawg txawm tias muaj cov kab mob tshwm sim.
