Chiwerengero cha anthu omwe ali ndi matenda ndi kufa padziko lonse lapansi chikupitilira kukwera kuyambira pomwe mliri wa COVID-19 udayamba.Pofika Seputembala 2021, chiwopsezo cha kufa padziko lonse lapansi kuchokera ku COVID-19 chidadutsa 4.5 miliyoni, ndi milandu yopitilira 222 miliyoni.
COVID-19 ndiyowopsa, ndipo sitingathe kumasuka.Kuzindikira msanga, kupereka lipoti, kudzipatula msanga komanso kulandira chithandizo msanga ndikofunikira kuti muchepetse njira yopatsira kachilomboka.
Ndiye mungazindikire bwanji Novel Coronavirus Virus?
Kuzindikira kwa COVID-19 nucleic acid ndikuyesa ndikuwunika milandu yotsimikizika ya COVID-19, omwe akuganiziridwa kuti ali ndi COVID-19 komanso anthu omwe ali ndi kachilomboka pogwiritsa ntchito njira za labotale.
1. Fluorescence njira yeniyeni ya PCR
Njira ya PCR imatanthawuza njira ya polymerase chain reaction, yomwe imachulukitsa kwambiri DNA yaing'ono.Kuti muzindikire Coronavirus yatsopano, monga buku la Coronavirus ndi kachilombo ka RNA, viral RNA iyenera kulembedwa m'malo mwa DNA PCR isanadziwike.
Mfundo ya kuzindikira kwa fluorescence PCR ndi: ndi kupita patsogolo kwa PCR, zomwe zimapangidwira zimapitilira kudziunjikira, ndipo mphamvu ya siginecha ya fluorescence imakulanso molingana.Pomaliza, njira yokhotakhota ya fluorescence idapezedwa poyang'anira kusintha kwa kuchuluka kwazinthu kudzera pakusintha kwamphamvu ya fluorescence.Iyi ndiye njira yomwe imagwiritsidwa ntchito kwambiri poyesa mayeso a Coronavirus nucleic acid.
Komabe, mavairasi a RNA amawonongeka mosavuta ngati sanasungidwe bwino kapena kutumizidwa kuti akafufuzidwe panthaŵi yake.Choncho, mutatha kupeza zitsanzo za odwala, ziyenera kusungidwa m'njira yovomerezeka ndikuyesedwa mwamsanga.Apo ayi, zikhoza kubweretsa zotsatira zolakwika za mayeso.
Machubu oyesa ma virus (Amagwiritsidwa ntchito kusonkhanitsa, kutumiza ndi kusungira zitsanzo za kachilombo ka DNA/RNA.)
2. Kuphatikiza kafukufuku anangula polymerization sequencing njira
Mayesowa amagwiritsa ntchito zida zapadera kuti azindikire ma jini omwe amatsatiridwa ndi ma nanospheres a DNA pamasinthidwe otsatizana.
Kuzindikira kwa mayesowa ndikwambiri, ndipo sikophweka kuphonya matenda, koma zotsatira zake zimakhudzidwanso mosavuta ndi zinthu zosiyanasiyana komanso zolakwika.
3. Thermostatic amplification chip njira
Mfundo yodziwira imatengera kuphatikiza kophatikizika kwa ma nucleic acid pakati pakupanga njira yodziwira, yomwe imatha kugwiritsidwa ntchito poyesa kuchuluka kapena kuchuluka kwa ma nucleic acid m'thupi la zamoyo.
4. Kuzindikira ma antibody
Zida zodziwira ma antibodies zimagwiritsidwa ntchito pozindikira ma antibodies a IgM kapena IgG opangidwa ndi thupi la munthu kachilomboka kamalowa m'thupi.Ma antibodies a IgM amawonekera kale ndipo ma antibodies a IgG amawonekera pambuyo pake.
5. Njira yagolide ya Colloidal
Njira ya golidi ya Colloidal ndiyo kugwiritsa ntchito pepala loyesa golide wa colloidal kuti azindikire, zomwe nthawi zambiri zimanenedwa pamapepala oyeserera mwachangu.Kuwunika kotereku kumakhala mkati mwa mphindi 10 ~ 15 kapena nthawi zambiri, kumatha kupeza zotsatira.
6. Chemiluminescence ya maginito particles
Chemiluminescence ndi immunoassay yodziwika kwambiri yomwe ingagwiritsidwe ntchito kutsimikizira antigenicity ya zinthu.Njira ya maginito ya chemiluminescence imatengera kuzindikira kwa chemiluminescence, ndikuwonjezera maginito nanoparticles, kotero kuti kuzindikira kumakhala ndi chidwi chachikulu komanso kuthamanga kwachangu.
Mayeso a COVID-19 nucleic acid VS antibody test, omwe mungasankhe?
Mayeso a Nucleic acid akadali mayeso okhawo omwe amagwiritsidwa ntchito kutsimikizira matenda a Novel coronavirus. Pamilandu yomwe akuganiziridwa kuti ali ndi kachilombo koyambitsa matenda a Coronavirus nucleic acid, kuyesa kwa antibody kumatha kugwiritsidwa ntchito ngati chizindikiro chowonjezera.
Novel Coronavirus(2019-nCoV) Nucleic Acid Detection Kit (Fluorescence PCR Method), Nucleic acid kuyeretsa zitsanzo 32 zitha kutha pakangotha mphindi 20.
