Nucleic acid kuyedzwa ndeye kuona kana paine nucleic acid (RNA) yeiyo coronavirus nyowani mumuviri wechidzidzo chebvunzo. Iyo nucleic acid yevhairasi yega yega ine ribonucleotides, uye nhamba uye kurongeka kweribonucleotides iri mumavhairasi akasiyana zvakasiyana, zvichiita kuti hutachiona hwega hwega huve hwakananga.
Iyo nucleic acid yeiyo coronavirus nyowani zvakare yakasarudzika, uye nucleic acid yekuona ndiyo chaiyo yekuona iyo nucleic acid yeiyo coronavirus itsva. Usati waongororwa nucleic acid, zvinodikanwa kuunganidza sputum yenyaya, swab yehuro, bronchoalveolar lavage fluid, ropa, nezvimwewo, uye nekuyedza masamples aya, zvinogona kuwanikwa kuti turakiti rekufema remudzidzi rine utachiona. Nyowani coronavirus nucleic acid yekuona inowanzo shandiswa pahuro swab sampuli yekuona. Sample inopatsanurwa uye inocheneswa, uye iyo inogona kuitika coronavirus nucleic acid inobviswa mairi, uye gadziriro dzebvunzo dzagadzirira.

Nyowani coronavirus nucleic acid yekuona inonyanya kushandisa fluorescence kuwanda kweRT-PCR tekinoroji, inova musanganiswa wefluorescence quantitative PCR tekinoroji uye RT-PCR tekinoroji. Mukuita kwekuona, RT-PCR tekinoroji inoshandiswa kudzosera kumashure kunyorera nucleic acid (RNA) yekoronavirus itsva muinowirirana deoxyribonucleic acid (DNA); ipapo fluorescence quantitative PCR tekinoroji inoshandiswa kudzokorora iyo yakawanikwa DNA muhuwandu hukuru. DNA yakadzokororwa inoonekwa uye yakanyorwa nekuongorora bonde. Kana paine nyowani coronavirus nucleic acid, chiridzwa chinogona kuona chiratidzo chefluorescent, uye, sezvo DNA ichiramba ichidhinda, chiratidzo chefluorescent chinoramba chichiwedzera, nekudaro chichiona kuvepo kweiyo coronavirus nyowani.
