Ko te whakamatautau waikawa nucleic he tino mohio mena he waikawa nucleic (RNA) o te coronavirus hou kei roto i te tinana o te kaupapa whakamatautau.Kei roto i te waikawa karihi o ia huaketo he ribonucleotides, a he rereke te maha me te raupapa o nga ribonucleotides kei roto i nga momo wheori rereke, he mea motuhake ia huaketo.
He ahurei ano te waikawa karihi o te coronavirus hou, a ko te kitenga waikawa karihi ko te kitenga motuhake o te waikawa karihi o te coronavirus hou.I mua i te whakamatautau waikawa karihi, he mea tika kia kohia nga tauira o te rewharewha o te kaupapa, te korokoro o te korokoro, te wai horoi bronchoalveolar, te toto, me etahi atu, a ma te whakamatautau i enei tauira, ka kitea kua pangia te rewharewha o te kaupapa ki te huakita.Ko te kitenga o te waikawa karihi coronavirus hou e whakamahia ana mo te kimi tauira mo te korokoro.Ka wehea te tauira, ka purea, ka tangohia mai i te waikawa nucleic coronavirus hou, kua rite nga whakaritenga mo te whakamatautau.

Ko te kitenga o te waikawa karihi coronavirus hou te nuinga o te whakamahi i te hangarau RT-PCR ine ine, he huinga o te hangarau PCR ine ine me te hangarau RT-PCR.I roto i te tukanga rapunga, ka whakamahia te hangarau RT-PCR ki te whakamuri i te tuhi i te waikawa karihi (RNA) o te coronavirus hou ki roto i te waikawa deoxyribonucleic (DNA);katahi ka whakamahia te hangarau PCR ine rewharewha ki te tukurua i te DNA kua whiwhi i roto i nga rahinga nui.Ka kitea te DNA kua tukuna, ka tapaina ki te tirotiro ira tangata.Mena he waikawa nucleic coronavirus hou, ka taea e te taputapu te kite i te tohu fluorescent, a, i te mea kei te haere tonu te DNA, kei te piki haere tonu te tohu fluorescent, na reira ka kite au i te aroaro o te coronavirus hou.
