COVID-19 IgG/IgM Rapid Test Cassette

Kwa akatswiri komanso mu vitro diagnostic ntchito kokha.

ZOYENERA KUGWIRITSA NTCHITO

TheCOVID-19 IgG/IgM Rapid Test Cassettendi lateral flow immunoassay yopangidwira kuzindikira kwabwino kwa ma antibodies a IgG ndi IgM ku kachilombo ka SARS-CoV-2 m'magazi athunthu, seramu kapena plasma zitsanzo kuchokera kwa anthu omwe akuwaganizira kuti ali ndi kachilombo ka COVID -19 ndi wothandizira zaumoyo wawo.

Mayeso a CO VID-19 IgG/IgM Rapid ndi chithandizo chozindikiritsa odwala omwe akuganiziridwa kuti ali ndi kachilombo ka SARS -CoV-2 molumikizana ndikuwonetsa zachipatala komanso zotsatira za mayeso ena a labotale.Amalangizidwa kuti agwiritse ntchito ngati chowunikira chowonjezera pa milandu yomwe akuwakayikira omwe ali ndi mayeso olakwika a nucleic acid ya novel coronavirus kapena kugwiritsidwa ntchito limodzi ndi mayeso a nucleic acid pamilandu yomwe akuwakayikira.Zotsatira zochokera pakuyezetsa ma antibody siziyenera kugwiritsidwa ntchito ngati njira yokhayo yodziwira kapena kupatula matenda a SARS -CoV-2 kapena kudziwitsa za matendawa.

Zotsatira zoyipa sizimaletsa matenda a SARS -CoV-2, makamaka kwa omwe adakumana ndi anthu odziwika omwe ali ndi kachilomboka kapena m'malo omwe ali ndi matenda ambiri.Kuyezetsa kotsatira ndi kufufuza kwa maselo kuyenera kuganiziridwa kuti kuthetse matenda mwa anthuwa.

Zotsatira zabwino zitha kukhala chifukwa cha matenda am'mbuyomu kapena apano omwe si a SARS-CoV-2 coronavirus strains.

Mayesowa amapangidwa kuti azigwiritsidwa ntchito m'ma laboratories azachipatala kapena ogwira ntchito yazachipatala pamalo osamalira, osati kugwiritsidwa ntchito kunyumba.Kuyezetsa kuyenera kugwiritsidwa ntchito powunika magazi omwe aperekedwa.

CHIDULE

Novel coronaviruses ndi a p genus.COVID 19ndi pachimake kupuma matenda opatsirana.Nthawi zambiri anthu amavutika.Pakadali pano, odwala omwe ali ndi kachilombo ka coronavirus ndiye gwero lalikulu la matenda;jekeseni wa asymptomatic angakhalenso gwero lopatsirana.Malingana ndi kafukufuku wamakono wa epidemiological, nthawi yoyamwitsa ndi masiku 1 mpaka 14, makamaka masiku 3 mpaka 7.The mawonetseredwe aakulu monga malungo, kutopa ndi youma chifuwa.Kutsekeka kwa mphuno, mphuno, zilonda zapakhosi, myalgia ndi kutsekula m'mimba zimapezeka nthawi zingapo.

Kachilombo ka SARS-CoV2 kakalowa m'thupi, RNA, chibadwa cha kachilomboka, ndiye chizindikiro choyamba chomwe chitha kuzindikirika.Mbiri ya virus ya SARS-CoV-2 ndi yofanana ndi chimfine, chomwe chimafika pachimake nthawi yazizindikiro, kenako ndikuyamba kuchepa.Ndi chitukuko cha matendawa pambuyo pa matenda, chitetezo cha mthupi cha munthu chidzatulutsa ma antibodies, omwe IgM ndi antibody yoyambirira yopangidwa ndi thupi pambuyo pa matenda, kusonyeza gawo lalikulu la matenda.Ma antibodies a IgG opita ku SARS-CoV2 amatha kuzindikirika pambuyo pa matenda.Zotsatira zabwino za IgG ndi IgM zitha kuchitika pambuyo pa matenda ndipo zitha kuwonetsa matenda owopsa kapena aposachedwa.IgG ikuwonetsa gawo lokhazikika la matenda kapena mbiri ya matenda am'mbuyomu.

Komabe, onse a IgM ndi IgG amakhala ndi nthawi yazenera kuchokera ku kachilombo ka virus kupita kukupanga ma antibody, IgM imatsala pang'ono kuwoneka matenda atayamba masiku angapo, kotero kuti kuzindikira kwawo nthawi zambiri kumatsalira kumbuyo kwa nucleic acid kuzindikira ndipo sikumva bwino kuposa kuzindikira kwa nucleic acid.Ngati ma nucleic acid amplification mayeso alibe ndipo pali kulumikizana kolimba kwa epidemiologicalCOVID 19matenda, zitsanzo za seramu zophatikizika (mu gawo lachimake ndi chotsitsimula) zitha kuthandizira kuzindikira.

MFUNDO

COVID-19 IgG/IgM Rapid Test Cassette (WB/S/P) ndi kaseti yoyezetsa bwino ya nembanemba yozikidwa pa immunoassay yozindikira ma antibodies (IgG ndi IgM) ku Novel coronavirus mu Magazi Onse / Seramu / plasma.Kaseti yoyesera imakhala ndi:1) pad yamtundu wa burgundy coiyugate yokhala ndi Novel coronavirus recombinant envelopu antigens coi^yokhala ndi golide wa Colloid (Novel coronavirus c两ugates), 2) mzere wa membrane wa nitrocellulose wokhala ndi mizere iwiri yoyesera (mizere ya IgG ndi IgM) ndi mzere wowongolera (C mzere).Mzere wa IgM udakutidwa kale ndi Mouse anti-Human IgM antibody, mzere wa IgG umakutidwa ndi anti-Human IgG antibody, pomwe kuchuluka kokwanira kwa kaseti kakang'ono kumaperekedwa mu chitsime cha kaseti yoyesera.Chitsanzocho chimayenda ndi capillary action kudutsa kaseti.IgM anti-Novel coronavirus, ngati ilipo pachitsanzocho, ilumikizana ndi Novel coronavirus coiyugates.Immunocomplex imatengedwa ndi reagent yomwe idakutidwa kale pa band ya IgM, ndikupanga mzere wamtundu wa IgM wamtundu wa burgundy, kuwonetsa zotsatira za mayeso a Novel coronavirus IgM.IgG anti-Novel coronavirus yomwe ikupezeka pachitsanzo ichi idzalumikizana ndi Novel coronavirus conjugates.Immunocomplex imatengedwa ndi reagent yomwe idakutidwa pamzere wa Lhe IgG, ndikupanga mzere wa IgG wamtundu wa burgundy, kuwonetsa zotsatira za mayeso a Novel coronavirus IgG.Kusakhalapo kwa mizere ya T (IgG ndi IgM) kumasonyeza a

zotsatira zoipa.Kuti ikhale yoyang'anira njira, mzere wachikuda udzawonekera nthawi zonse pagawo la mzere wosonyeza kuti chiwerengero choyenera cha chitsanzo chawonjezeredwa ndipo kupukuta kwa membrane kwachitika.

KUMASULIRIDWA KWA ZOTSATIRA

ma antibodies.Mawonekedwe a mzere woyeserera wa IgM akuwonetsa kukhalapo kwa ma antibodies a Novel coronavirus enieni a IgM.Ndipo ngati mzere wa IgG ndi IgM ukuwonekera, zikuwonetsa kuti kupezeka kwa ma antibodies a Novel coronavirus enieni a IgG ndi IgM.

Zoipa:Mzere umodzi wachikuda umapezeka m'chigawo chowongolera (C), Palibe mzere wowoneka bwino wamtundu womwe umapezeka m'chigawo choyesera.

Zosavomerezeka:Mzere wowongolera ukulephera kuwonekera.Kusakwanira kwa kuchuluka kwa zitsanzo kapena njira zolakwika ndizomwe zimapangitsa kuti fbr control linefailure.Unikaninso ndondomekoyi ndikubwereza mayesowo ndi kaseti yatsopano yoyeserera.Vuto likapitilira, siyani kugwiritsa ntchito zida zoyeserera nthawi yomweyo ndipo funsani wofalitsa wapafupipafupi.

KUKHALA KWAKHALIDWE

Kuwongolera kwadongosolo kumaphatikizidwa muyeso.Mzere wachikuda womwe ukuwoneka m'chigawo chowongolera (C) umatengedwa ngati njira yoyendetsera mkati.Imatsimikizira kuchuluka kokwanira kwa sampuli, kupukuta kokwanira kwa membrane ndi njira yoyenera.Miyezo yowongolera siyikuperekedwa ndi zida izi.Komabe, tikulimbikitsidwa kuti zowongolera zabwino ndi zoyipa ziyesedwe ngati machitidwe abwino a labotale kuti atsimikizire njira yoyezera ndikuwonetsetsa momwe mayeso akuyendera.

ZOPHUNZITSA

• Makaseti a COVID-19 IgG/IgM Rapid Test (WB/S/P) ali ndi malire kuti apereke mawonekedwe abwino

kuzindikira.Kuchulukira kwa mzere woyesera sikumayenderana kwenikweni ndi kuchuluka kwa antibody m'magazi.Zotsatira zomwe zapezedwa kuchokera ku mayesowa zimapangidwira kuti zikhale chithandizo cha matenda okha.Dokotala aliyense ayenera kutanthauzira zotsatira zake mogwirizana ndi mbiri ya wodwalayo, zomwe apeza, ndi njira zina zowunikira.

• Zotsatira zosonyeza kuti ma antibodies ku Novel coronavirus sapezeka kapena ali pamlingo womwe sunawonekere pakuyezetsa.

ZINTHU ZOCHITIKA

Kuyerekeza kwachiwerengero kunapangidwa pakati pa zotsatira zomwe zimapereka chidwi cha 88.61%, kutsimikizika kwa 97.67% ndi kulondola kwa 93.33%

Cross-Reactivity ndi Kusokoneza

1 .Zina zomwe zingayambitse matenda opatsirana zinayesedwa kuti zigwirizane ndi mayesero.Zitsanzo zina zabwino za matenda ena opatsirana zidalowetsedwa mu Novel coronavirus zabwino ndi zoyipa zomwe zidayesedwa padera.Palibe kuyanjananso komwe kunawonedwa ndi zitsanzo za odwala omwe ali ndi kachilombo ka HIV, HA ^ HBsAg, HCV TP, HTIA ^ CMV FLUA, FLUB, RSy MP, CP, HPIVs.

2. Zinthu zomwe zimatha kugwira ntchito mopitilira muyeso kuphatikiza zigawo zodziwika bwino za seramu, monga lipids, hemoglobin, bilirubin, zidakwezedwa mozama kwambiri mu Novel coronavirus zitsanzo zabwino ndi zoyipa ndikuyesedwa, padera.

Palibe kuwoloka kapena kusokoneza komwe kunawonedwa pa chipangizocho.

3. Ofufuza ena odziwika bwino a zamoyo adalowetsedwa mu Novel coronavirus zitsanzo zabwino komanso zoyipa ndikuyesedwa padera.Palibe kusokoneza kwakukulu komwe kunawonedwa pamagulu omwe alembedwa mu tebulo ili m'munsimu.

Kuberekanso

Maphunziro obwerezabwereza adachitidwa pa Novel coronavirus IgG/IgM Rapid Test m'malo atatu azachipatala (POL).Zitsanzo za seramu zachipatala makumi asanu ndi limodzi (60), 20 zoipa, 20 za m'malire zabwino ndi 20 zabwino, zinagwiritsidwa ntchito mu phunziroli.Chitsanzo chilichonse chinayendetsedwa katatu kwa masiku atatu pa POL iliyonse.Mapangano a intra-assay anali 100%.Chigwirizano chapakati pa malo chinali 100%.
