Palo ea lefats'e ea ts'oaetso le mafu e ntse e eketseha ho tloha ha seoa sa COVID-19 se qala.Ho tloha ka Loetse 2021, lenane la ba shoang lefats'eng ka bophara ho tsoa ho COVID-19 le fetile limilione tse 4.5, ka linyeoe tse fetang limilione tse 222.
COVID-19 e tebile, 'me ha re khone ho phomola.Ho lemoha kapele, ho fana ka tlaleho ea pele, ho itšehla thajana le ho phekoloa kapele hoa hlokahala ho khaola ka potlako tsela ea phetiso ea kokoana-hloko.
Joale u ka tseba joang Novel Coronavirus Virus?
Ho fumana COVID-19 nucleic acid ke tlhahlobo le tlhahlobo ea linyeoe tse netefalitsoeng tsa COVID-19, ho belaelloang linyeoe tsa COVID-19 le batho ba nang le tšoaetso ea asymptomatic ka mekhoa ea laboratori.
1. Mokhoa oa PCR oa Fluorescence oa nako ea sebele
Mokhoa oa PCR o bua ka polymerase chain reaction, e eketsang haholo palo e nyane ea DNA.Bakeng sa tšibollo ea "Coronavirus" e ncha, joalo ka ha "Coronavirus" e le vaerase ea RNA, RNA ea vaerase e hloka ho fetoleloa ho DNA pele PCR e fumanoa.
Molao-motheo oa ho lemoha ha PCR ea fluorescence ke: ka tsoelo-pele ea PCR, lihlahisoa tsa karabelo li tsoela pele ho bokella, 'me matla a lets'oao la fluorescence le ona a eketseha ka ho lekana.Qetellong, seketsoana sa amplification sa fluorescence se ile sa fumanoa ka ho shebella phetoho ea bongata ba sehlahisoa ka ho fetoha ha matla a fluorescence.Hona joale ona ke mokhoa o sebelisoang haholo bakeng sa liteko tse ncha tsa Coronavirus nucleic acid.
Leha ho le joalo, livaerase tsa RNA li senyeha habonolo haeba li sa bolokoe hantle kapa li sa romeloe bakeng sa tlhahlobo ka nako.Ka hona, ka mor'a ho fumana lisampole tsa bakuli, li hloka ho bolokoa ka mokhoa o tloaelehileng le ho hlahlojoa kapele kamoo ho ka khonehang.Ho seng joalo, ho ka 'na ha lebisa liphellong tse sa nepahalang tsa liteko.
Li-tubes tsa sampole tsa vaerase (E sebelisetsoa ho bokella, ho tsamaisa le ho boloka disampole tsa DNA/RNA virus.)
2. Mokhoa o kopantsoeng oa probe anchored polymerization sequencing
Teko ena haholo-holo e sebelisa lisebelisoa tse khethehileng ho bona tatellano ea liphatsa tsa lefutso tse tsamaisoang ke DNA nanospheres ho tatellano ea li-slide.
Boikutlo ba tlhahlobo ena bo phahame, 'me ha ho bonolo ho lahleheloa ke ho hlahlojoa, empa liphello li boetse li ameha habonolo ke lintlha tse sa tšoaneng le tse sa nepahaleng.
3. Thermostatic amplification chip mokhoa
Molao-motheo oa ho lemoha o ipapisitse le motsoako o tlatselletsang oa li-nucleic acid lipakeng tsa nts'etsopele ea mokhoa oa ho lemoha, o ka sebelisoang bakeng sa tekanyo ea boleng kapa palo ea li-nucleic acid 'meleng oa lintho tse phelang.
4. Ho lemoha antibody ea kokoana-hloko
Li-antibody reagents li sebelisoa ho lemoha li-antibodies tsa IgM kapa IgG tse hlahisoang ke 'mele oa motho ka mor'a hore kokoana-hloko e kene' meleng.Li-antibodies tsa IgM li hlaha pejana 'me li-antibodies tsa IgG li hlaha hamorao.
5. Mokhoa oa khauta oa Colloidal
Mokhoa oa khauta oa Colloidal ke ho sebelisa pampiri ea tlhahlobo ea khauta ea colloidal bakeng sa ho lemoha, eo hangata ho thoeng hajoale pampiri ea tlhahlobo e potlakileng ea tlhahlobo.Tlhahlobo ea mofuta ona e nka metsotso e 10 ~ 15 kapa ho feta moo, e ka fumana sephetho sa tlhahlobo.
6. Chemiluminescence ea likaroloana tsa makenete
Chemiluminescence ke immunoassay e nang le kutloelo-bohloko e ka sebelisoang ho fumana hore na lintho li antigenicity.Magnetic particle chemiluminescence mokhoa o ipapisitse le tlhahlobo ea chemiluminescence, o eketsa li-nanoparticles tsa makenete, e le hore phumano e be le kutlo e phahameng le lebelo la ho lemoha kapele.
Teko ea COVID-19 nucleic acid VS antibody test, eo u ka e khethang?
Liteko tsa Nucleic acid e ntse e le tsona feela liteko tse sebelisoang ho netefatsa tšoaetso ea Novel coronavirus. Bakeng sa linyeoe tse belaelloang tsa "Coronavirus" nucleic acid negative test, antibody test e ka sebelisoa e le sesupo sa tlatsetso.
Novel Coronavirus(2019-nCoV) Nucleic Acid Detection Kit (Fluorescence PCR Method), tlhoekiso ea lisampole tse 32 tsa Nucleic acid e ka phethoa ka nako e ka bang metsotso e 20.
