Huwandu hwepasi rose hwehutachiona uye kufa huri kuramba huchikwira kubva pakatanga denda reCCIDID-19.Kubva munaGunyana 2021, huwandu hwevanhu vafa pasi rose kubva kuCOVID-19 hwakapfuura mamirioni mana nemazana mashanu, uye vanopfuura mamirioni mazana maviri nemakumi maviri nevaviri.
COVID-19 yakakomba, uye isu hatigone kuzorora.Kuonekwa kwekutanga, kuzivisa kwekutanga, kuzviparadzanisa nevamwe uye kurapwa nekukurumidza kunofanirwa kugura nzira yekutapurira hutachiona.
Saka maitiro ekuona Novel Coronavirus Virus?
COVID-19 nucleic acid yekuona ndeye kuyedza uye kuongorora nyaya dzakasimbiswa dzeCCIDID-19, dzinofungidzirwa kuti dzeCCIDID-19 uye vanhu vane hutachiona hweasymptomatic kuburikidza nenzira dzemurabhoritari.
1. Fluorescence chaiyo-nguva PCR nzira
Iyo PCR nzira inoreva iyo polymerase chain reaction, iyo inowedzera zvinoshamisa huwandu hudiki hweDNA.Nekuonekwa kweCoronavirus novel, senge novel Coronavirus hutachiona hweRNA, hutachiona RNA hunofanirwa kunyorerwa muDNA PCR isati yaonekwa.
Nheyo yefluorescence PCR yekuona ndeiyi: nekufambira mberi kwePCR, maitiro ekuita anoramba achiunganidza, uye kusimba kwechiratidzo chefluorescence kunowedzerawo zvakaenzana.Pakupedzisira, fluorescence amplification curve yakawanikwa nekutarisa shanduko yehuwandu hwechigadzirwa kuburikidza nekushandurwa kwefluorescence intensity.Iyi ndiyo parizvino nzira inonyanya kushandiswa yenovel Coronavirus nucleic acid bvunzo.
Nekudaro, mavhairasi eRNA anoshatiswa nyore nyore kana asina kuchengetedzwa zvakanaka kana kuendeswa kunoongororwa nenguva.Naizvozvo, mushure mekuwana sampuli dzevarwere, dzinofanirwa kuchengetwa nenzira yakajairwa uye kuongororwa nekukurumidza sezvinobvira.Zvikasadaro, zvinogona kutungamira kune zvisiri izvo bvunzo mhinduro.
Virus sampling tubes (Inoshandiswa kuunganidza, kutakura uye kuchengetedza DNA / RNA hutachiona sampuli.)
2. Yakasanganiswa probe anchored polymerization sequencing nzira
Muedzo uyu unonyanya kushandisa zviridzwa zvehunyanzvi kuona kutevedzana kwemajini anotakurwa neDNA nanospheres pakutevedzana kwemasiraidhi.
Kunzwisiswa kwemuedzo uyu kwakakwirira, uye hazvisi nyore kupotsa kuongororwa, asi migumisiro inobatwawo nyore nyore nezvinhu zvakasiyana-siyana uye zvisina kururama.
3. Thermostatic amplification chip nzira
Detection musimboti wakavakirwa pamubatanidzwa wekusanganisa nucleic acids pakati pekuvandudzwa kwenzira yekuona, inogona kushandiswa kuyera kana kuwanda kuyerwa kwema nucleic acids mumuviri wezvipenyu.
4. Kuonekwa kwehutachiona hwehutachiona
Maantibody anoona reagents anoshandiswa kuona IgM kana IgG masoja ekudzivirira chirwere anogadzirwa nemuviri wemunhu mushure mekunge hutachiona hwapinda mumuviri.Masoja ekudzivirira chirwere eIgM anoonekwa kare uye masoja ekudzivirira chirwere eIgG anozoonekwa gare gare.
5. Colloidal goridhe nzira
Colloidal goridhe nzira ndeye kushandisa colloidal goridhe bvunzo bepa kuona, iyo inowanzo taurwa pari zvino nekukurumidza kuona bepa rekuongorora.Rudzi urwu rwekuongorora rwuri mu10 ~ 15 maminetsi kana zvakadaro kazhinji, inogona kuwana mhedzisiro yekuona.
6. Chemiluminescence yemagnetic particles
Chemiluminescence inyanzvi yekudzivirira immunoassay inogona kushandiswa kuona antigenicity yezvinhu.Magnetic particle chemiluminescence nzira yakavakirwa pachemiluminescence yekuona, ichiwedzera magineti nanoparticles, kuitira kuti kucherechedzwa kuve nekunzwa kwakanyanya uye nekukurumidza kuona nekukurumidza.
COVID-19 nucleic acid bvunzo VS antibody bvunzo, ndeipi yekusarudza?
Nucleic acid tests ichiri bvunzo dzega dzinoshandiswa kusimbisa hutachiona hweNovel coronavirus. Kune vanofungidzirwa nyaya dzenovel Coronavirus nucleic acid negative test, antibody test inogona kushandiswa sechiratidzo chekuwedzera.
Novel Coronavirus(2019-nCoV) Nucleic Acid Detection Kit (Fluorescence PCR Method), Nucleic acid kucheneswa kwemasampuli makumi matatu nembiri kunogona kupedzwa mukati memaminitsi makumi maviri.
