Cov ntsiab lus paub txog kab mob
1. Sau cov qauv: tus kabmob tshiab no yog los ntawm cov mural ntawm tib neeg lub cev, yog li peb yuav tsum hu
Sau cov qauv los ntawm lub tshuab nqus tsev. Kev so yog nrog caj pas swab, qhov ntswg qhov ntswg hauv phau ntawv dhau los (pharynx lossis qhov ntswg kab noj hniav)
Swab collection: Lwm qhov yog sau cov kua hauv caj pas, cov kua dej lavage, thiab cov kua dej alveolar lavage.
2. Peeling thiab tev: daim tawv nqaij yog qhwv ib ncig ntawm sab nraud.
puas lawm. Tom qab peb sau cov qauv, peb tshem tawm qhov chaw ntawm tus kab mob los ntawm cov tshuaj lom neeg ua kom lub cev,
Nws yog" streaking" RNA.
3. Luam, luam tawm thiab luam tawm: Tom qab rho tawm RNA fragment, siv PCR (polymerase saw rov qab
Yuav tsum) txoj kev los luam qhov ntawd thiab lub lens ntawd. Zoo li peb pom ib qho tshwj xeeb"tag"
Koj tuaj yeem txheeb xyuas cov ntaub ntawv tshwj xeeb tshaj plaws txog tus kabmob tshiab no, thiab tom qab ntawd txheeb xyuas nws tom qab txheeb xyuas nws
Tom qab duplication, qhov zoo ntawm qhov xwm txheej duplication nce mus txog kaum ntawm billions qib, nws yooj yim mus nrhiav tau.
4. Fluorescence" pom kev": Yuav kom nrhiav tau tus kab mob nucleic acid yooj yim dua, peb ntxiv
Ntxig lub fluorescent sojntsuam rau daim ntawv lo, thiab tom qab ntawd siv lub ntsuas ntsuas los nyeem cov fluorescence siv kom tau qhov nkhaus fluorescence. Nyob rau lub sijhawm no, cov ntaub ntawv ntawm tus kab mob coronary pneumonia tshiab tuaj yeem ntes tau.
Pros thiab cons
Qhov zoo: kev tshawb nrhiav nucleic acid muaj qhov zoo ntawm qhov ntxov, rhiab thiab siab tshwj xeeb. Kev kuaj caj ces
Qhov rhiab heev yog qhov siab vim nws muaj cov txheej txheem gene amplification, uas tuaj yeem nthuav cov noob sib lawv liag rau hauv ntau yam, uas yooj yim rau kev txiav txim siab. Qhov no yog qhov zoo tshaj ntawm kev ntsuam xyuas caj ces. Qhov tshwj xeeb yog tias cov noob nthuav dav siv 2 cov noob tshwj xeeb ntawm tus kabmob tshiab. Ib ntus, tsuav yog kuaj pom cov noob kab mob, nws txhais tau tias nws kis tau.
Qhov tsis zoo: Nyob rau theem pib ntawm qhov pib ntawm tus neeg mob, tus nqi ntawm tus kab mob hauv lub cev yog me me, thiab nws nyuaj rau kev kuaj pom; qhov chaw, tus nqi, txoj kev khaws cia thiab lub sijhawm ntawm kev sau cov pa luam yeeb yuav tsim cov txiaj ntsig sib txawv rau qhov kev sim. sau
Cov qauv no yog kev ua haujlwm qhib, uas yuav ua rau muaj kev pheej hmoo ntawm kev kis tus kab mob mus rau tus kws kho mob kuaj.
