SARS-CoV-2 Neutralizing antibody Test Cassette

Rau qhov kev soj ntsuam zoo ntawm tus kab mob Coronavirus 2019 (2019-nCOV lossis COVID -19) neutralizing antibody hauv tib neeg cov ntshav ntshav / ntshav / ntshav tag nrho.

Rau cov kws tshaj lij hauv Vitro Diagnostic Siv nkaus xwb

【TUS SIV】

The SARS-CoV-2 Neutralizing antibody Test Cassette yog cov chromatographic ceev

immunoassay rau qhov kev kuaj pom zoo ntawm neutralizing tshuaj tiv thaiv kab mob Coronavirus 2019 hauv tib neeg cov ntshav, ntshav, lossis ntshav raws li kev pabcuam hauv Kev Ntsuas qib ntawm tib neeg cov tshuaj tiv thaiv tus kabmob coronavirus neutralizing antibody titer.

mammals.Cov genus γ feem ntau ua rau noog kab mob.Cov kab mob kis tau los ntawm kev sib cuag ncaj qha nrog cov zais cia lossis los ntawm aerosols thiab cov tee dej. Kuj tseem muaj pov thawj tias nws tuaj yeem kis tau los ntawm txoj kev fecal-qhov ncauj.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, or 2019-nCoV) is an enveloped non-segmented positive-sense RNA virus. Nws yog qhov ua rau tus kabmob coronavirus 2019 (COVID-19), uas kis tau rau tib neeg.

SARS-CoV-2 muaj ntau yam qauv proteins xws li spike (S), hnab ntawv (E), membrane (M) thiab nucleocapsid (N). Spike protein (S) muaj cov receptor binding domain (RBD), uas yog lub luag haujlwm rau kev lees paub lub cell nto receptor, angiotensin converting enzyme-2 (ACE2). Nws tau pom tias RBD ntawm SARS-CoV-2 S protein cuam tshuam nrog tib neeg ACE2 receptor uas ua rau endocytosis rau hauv lub hlwb ntawm lub ntsws sib sib zog nqus thiab kis kab mob.

Kev kis tus kab mob SARS-CoV-2 pib lub cev tiv thaiv kab mob, uas suav nrog kev tsim cov tshuaj tiv thaiv hauv cov ntshav. Cov tshuaj tiv thaiv zais cia muab kev tiv thaiv tiv thaiv kab mob yav tom ntej los ntawm cov kab mob, vim tias lawv tseem nyob hauv cov hlab ntshav rau ntau lub hlis mus rau xyoo tom qab kis kab mob thiab yuav khi sai thiab muaj zog rau cov kab mob los thaiv cov cellular infiltration thiab replication. Cov tshuaj tiv thaiv no yog hu ua neutralizing antibodies.

【SPEIMEN COLLECTION THIAB KEV PAB CUAM】

1.The SARS-CoV-2 Neutralizing antibody Test Cassette yog tsim los siv rau tib neeg cov ntshav, ntshav lossis ntshav cov qauv nkaus xwb.

2.Tsuas yog cov qauv ntshiab, uas tsis yog-hemolyzed tau pom zoo siv nrog rau qhov kev sim no. Ntshav los yog ntshav ntshav yuav tsum tau muab cais kom sai li sai tau kom tsis txhob hemolysis.

3.Ua ntsuas tam sim tom qab sau cov qauv. Tsis txhob tso cov qauv ntawm chav tsev kub rau lub sijhawm ntev. Cov ntshav thiab cov ntshav plasma tuaj yeem khaws cia ntawm 2-8 ° C txog li 3 hnub. Rau kev khaws cia ntev, cov tshuaj ntshav los yog cov ntshav ntshav yuav tsum tau khaws cia hauv qab -20 ° C.Tag nrho cov ntshav sau los ntawm venipuncture yuav tsum tau khaws cia ntawm 2-8 ° C yog tias qhov kev sim yuav tsum tau khiav hauv 2 hnub tom qab sau.Tsis txhob khov tag nrho cov ntshav. cov qauv. Tag nrho cov ntshav sau los ntawm tus ntiv tes yuav tsum tau kuaj tam sim ntawd.

4.Cov thawv uas muaj cov tshuaj tiv thaiv coagulants xws li EDTA, citrate, los yog heparin yuav tsum tau siv rau tag nrho cov ntshav cia.Nqa cov qauv mus rau chav tsev kub ua ntej kuaj.

5.Cov khoom khov khov yuav tsum tau thawed tag nrho thiab sib xyaw kom zoo ua ntej kev sim. Tsis txhob rov khov dua

thiab thawing ntawm cov qauv.

6.Yog tias cov qauv yuav raug xa tawm, ntim lawv raws li tag nrho cov kev cai siv rau kev thauj mus los

ntawm etiological agents.

7.Icteric, lipemic, hemolyzed, tshav kub kho thiab paug sera tej zaum yuav ua rau erroneous tshwm sim.

8.Thaum sau cov ntshav ntiv tes nrog lub lancet thiab cawv cawv, thov muab pov tseg thawj zaug ntawm

cov ntshav.

1. Nqa lub hnab ntim rau hauv chav tsev kub ua ntej qhib. Tshem tawm cov khoom kuaj los ntawm lub hnab ntim thiab siv nws sai li sai tau.

2. Muab cov cuab yeej xeem tso rau ntawm qhov chaw huv thiab theem.

Rau cov ntshav los yog Plasma Specimens: Siv Micropipette, thiab hloov 5ul cov ntshav / ntshav mus rau cov qauv zoo ntawm cov cuab yeej kuaj, tom qab ntawd ntxiv 2 poob ntawm qhov tsis, thiab pib lub sijhawm.

Rau Cov Ntshav Tag Nrho (Venipuncture / Fingerstick) Cov Qauv: Tuav koj tus ntiv tes thiab maj mam nyem koj tus ntiv tes, siv cov khoom siv pov tseg pov tseg kom nqus 10ul ntawm tag nrho cov ntshav mus rau 10ul kab ntawm cov yas pov tseg, thiab hloov mus rau qhov chaw kuaj lub qhov (Yog tias tag nrho cov ntshav ntim ntau tshaj qhov cim, Thov tso cov ntshav tag nrho hauv lub pipette), tom qab ntawd ntxiv 2 poob ntawm qhov tsis, thiab pib lub sijhawm. Lus Cim: Cov qauv kuj tuaj yeem siv tau siv lub micropipette.

3. Tos kom cov kab xim muaj xim tshwm sim.Nyeem cov txiaj ntsig ntawm 15 feeb.Tsis txhob txhais cov txiaj ntsig tom qab 20 feeb.
