YUAV TSUM SIV
CovCOVID-19 Antigen Rapid Test Device(Colloidal Kub) yog ib qho tshuaj tiv thaiv kab mob sai sai rau qhov zoo, kev kuaj pom tus kab mob COVID-19 Antigens los ntawm oropharyngeal swabs thiab nasopharyngeal 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.
PRINCIPLE
Tus kab mob COVID-19 Antigen Rapid Test Device (Colloidal Gold) kuaj pom COVID-19 antigens los ntawm kev txhais cov duab ntawm kev tsim xim ntawm daim kab xev. COVID-19 cov tshuaj tiv thaiv yog immobilized nyob rau thaj tsam kuaj ntawm daim nyias nyias raws. Thaum lub sij hawm sim, cov khoom tawm tau hnov mob nrog kev tiv thaiv COVID-19 cov tshuaj tiv thaiv kab mob sib txuas rau cov xim muaj xim thiab muab tso rau hauv cov qauv ntawm qhov ntsuas. Cov sib tov ces migrate los ntawm daim nyias nyias los ntawm capillary kev txiav txim thiab interacts nrog reagents ntawm daim nyias nyias. Yog tias muaj COVID-19 antigens txaus nyob rau hauv cov qauv, cov xim muaj xim yuav tsim nyob rau hauv raws li cheeb tsam kuaj ntawm daim nyias nyias. Lub xub ntiag ntawm cov xim xim hauv cheeb tsam kuaj pom tau tias muaj txiaj ntsig zoo rau cov kab mob antigens tshwj xeeb, thaum nws qhov tsis tuaj yeem qhia qhov tshwm sim tsis zoo. Qhov tshwm sim ntawm cov xim xim ntawm thaj chaw tswj hwm ua haujlwm raws li kev tswj hwm txheej txheem, qhia tias qhov ntim zoo ntawm cov qauv tau muab ntxiv thiab daim nyias nyias wicking tau tshwm sim.
