Nnwale acid nucleic bụ n'ezie ịchọpụta ma enwere nucleic acid (RNA) nke coronavirus ọhụrụ n'ime ahụ nke isiokwu ule. Nucleic acid nke nje ọ bụla nwere ribonucleotides, na ọnụ ọgụgụ na usoro nke ribonucleotides dị na nje dị iche iche dị iche iche, na-eme ka nje ọ bụla pụta ìhè.
Nucleic acid nke coronavirus ọhụrụ bụkwa ihe pụrụ iche, na nchọpụta nucleic acid bụ nchọpụta kpọmkwem nke nucleic acid nke coronavirus ọhụrụ ahụ. Tupu nyocha nke acid nucleic, ọ dị mkpa ịnakọta ihe atụ nke sputum nke isiokwu ahụ, akpịrị akpịrị, bronchoalveolar lavage fluid, ọbara, wdg, site n'inyocha ihe nlele ndị a, a ga-achọpụta na akụkụ iku ume nke isiokwu ahụ na-ebute nje bacteria. A na-ejikarị nchọpụta nucleic acid ọhụrụ maka ịchọpụta ihe nlere akpịrị. A na-ekewa ihe nlele ahụ ma sachaa ya, a na-ewepụtakwa nucleic acid coronavirus ọhụrụ enwere ike, na nkwadebe maka ule ahụ adịla njikere.

Nchọpụta nucleic acid ọhụrụ nke coronavirus na-eji teknụzụ RT-PCR fluorescence quantitative, nke bụ ngwakọta nke teknụzụ PCR fluorescence quantitative na teknụzụ RT-PCR. N'ime usoro nchọpụta ahụ, a na-eji teknụzụ RT-PCR mee mgbanwe iji degharịa nucleic acid (RNA) nke coronavirus ọhụrụ n'ime deoxyribonucleic acid (DNA) kwekọrọ; mgbe ahụ, a na-eji teknụzụ PCR fluorescence quantitative PCR megharịa DNA enwetara n'ọtụtụ buru ibu. Achọpụtara DNA nke emegharịgharịrị wee tinye ya na nyocha mmekọahụ. Ọ bụrụ na e nwere ọhụrụ coronavirus nucleic acid, ngwá ọrụ nwere ike ịchọpụta fluorescent mgbaàmà, na, ka DNA na-aga n'ihu na-emepụtaghachi, fluorescent mgbaàmà na-aga n'ihu na-abawanye, si otú ahụ na-apụtaghị ìhè ọnụnọ nke ọhụrụ coronavirus.
