Kev kuaj Covid nrawm tau dhau los ua cov cuab yeej tseem ceeb hauv kev tawm tsam kev sib kis. Lawv tuaj yeem xa cov txiaj ntsig kuaj tau sai thiab raug, ua rau lawv muaj txiaj ntsig zoo hauv kev tswj kev kis tus kabmob. Hauv tsab xov xwm no, peb yuav piav qhia txog dab tsi yog nyob rau hauv Covid qhov kev sim nrawm nrawm, nws ua haujlwm li cas, thiab nws qhov tseem ceeb hauv Covid-19 kuaj.
Dab tsi yog Covid Rapid Test Buffer?
Kev kuaj mob ceev ceev tsis yog Covid yog cov kua tshuaj uas siv rau hauv cov kev ntsuam xyuas sab nraud. Qhov kev daws teeb meem no yuav pab kom dilute cov qauv thiab tsim kom muaj qhov chaw ruaj khov rau kev sim ua haujlwm kom zoo. Ib qho kev daws teeb meem tsis yog qhov tseem ceeb vim nws ua raws li keeb kwm yav dhau los rau qhov kev sim, ua kom yooj yim nyeem cov txiaj ntsig kom raug.
Qhov kev daws teeb meem tsis ua rau lub lateral flow test ua hauj lwm los ntawm kev tso cai rau cov qauv ntws los ntawm qhov kev sim ua ntej-coated membrane. Qhov kev sim kuaj pom cov protein tshwj xeeb lossis lwm yam tshuaj hauv cov qauv thiab hloov xim lossis ua lub teeb liab qhia tias muaj tus kab mob.
Muaj ntau hom kev daws teeb meem tsis siv neeg hauv Covid kev sim sai. Cia wb mus saib lawv.
Hom kev daws teeb meem tsis haum
1. Phosphate-buffered saline (PBS)
Phosphate-buffered saline (PBS) yog ib hom tshuaj tsis haum uas feem ntau siv hauv Covid kev sim sai. Nws yog cov kua ntsev uas ua kom cov pH ntawm cov qauv ruaj khov. Nws kuj tseem pab tiv thaiv kom tsis txhob degradation ntawm cov qauv, uas tuaj yeem ua rau cov txiaj ntsig tsis raug.
PBS feem ntau yog siv los ua thawj qhov kev daws teeb meem rau Covid kev sim sai. Nws pab kom dilute cov qauv thiab tsim ib qho chaw ruaj khov rau cov theem tom ntej ntawm kev xeem.
2. Tris-buffered saline (TBS)
Tris-buffered saline (TBS) yog lwm hom tshuaj tsis haum uas feem ntau siv hauv Covid kev sim sai. Nws zoo ib yam li PBS, tab sis nws muaj tus neeg sawv cev ntxiv hu ua Tris. Tris pab tswj cov pH ntawm cov qauv zoo dua li PBS.
TBS yog siv nyob rau theem tom qab ntawm Covid kev sim sai. Nws pab txhim kho cov kev tshwm sim uas tshwm sim los tsim cov teeb liab lossis hloov xim, ua kom yooj yim nyeem cov txiaj ntsig.
3. Phosphate-buffered saline nrog detergents (PBS-T)
Phosphate-buffered saline nrog cov tshuaj detergents (PBS-T) yog ib hom tshuaj tsis haum uas siv rau hauv Covid cov kev sim sai uas yuav tsum tau kuaj xyuas cov tshuaj tiv thaiv lossis lwm yam tshuaj hauv cov qauv.
Cov tshuaj detergents ntxiv rau cov tshuaj tsis pab txhawm rau txhawm rau cov cell membranes thiab tso tawm cov khoom txaus siab. Qhov no tso cai rau kev kuaj xyuas kom pom muaj cov tshuaj tiv thaiv kab mob lossis lwm yam tshuaj zoo dua.
Vim li cas Covid Rapid Test Buffer tseem ceeb?
Covid kev sim nrawm nrawm yog qhov tseem ceeb rau qhov raug thiab kev ntseeg siab ntawm kev sim Covid ceev. Cov txiaj ntsig tsis raug tuaj yeem ua rau kis tus kabmob, ua rau lub neej muaj kev pheej hmoo thiab ua rau nws nyuaj rau tswj tus kabmob kis.
Cov tshuaj tsis haum pab tsim kom muaj qhov chaw ruaj khov rau kev sim ua haujlwm, uas yog qhov tseem ceeb rau kev kuaj pom tus kab mob kom raug. Nws kuj tseem pab tiv thaiv kom tsis txhob degradation ntawm cov qauv, uas tuaj yeem ua rau cov txiaj ntsig tsis raug.
Cov tshuaj tsis haum kuj tseem ua lub luag haujlwm tseem ceeb hauv kev nkag siab ntawm qhov kev sim. Ib qho kev daws teeb meem uas tsis muaj zog los yog tsis muaj zog heev tuaj yeem cuam tshuam qhov rhiab heev ntawm qhov kev sim, ua rau cov txiaj ntsig tsis raug.

Covid kev sim nrawm nrawm yog qhov tseem ceeb ntawm kev kuaj Covid sai. Lawv pab tsim kom muaj qhov chaw ruaj khov rau qhov kev sim ua haujlwm, tiv thaiv qhov kev puas tsuaj ntawm cov qauv, thiab txhim kho qhov kev xav ntawm qhov kev xeem. Kev nkag siab txog qhov tseem ceeb ntawm cov kev daws teeb meem tsis nyob hauv Covid cov kev sim sai yog qhov tseem ceeb rau kev ua kom qhov tseeb thiab kev ntseeg siab ntawm cov txiaj ntsig kev xeem. Los ntawm kev ua haujlwm ua ke, peb tuaj yeem pab tswj kev kis tus kabmob thiab ua kom peb cov zej zog muaj kev nyab xeeb.
