Idanwo Nucleic acid jẹ gangan lati rii boya acid nucleic (RNA) wa ti coronavirus tuntun ninu ara ti koko-ọrọ idanwo naa.Acid nucleic ti kokoro kọọkan ni awọn ribonucleotides, ati nọmba ati aṣẹ ti ribonucleotides ti o wa ninu awọn ọlọjẹ oriṣiriṣi yatọ, ti o jẹ ki ọlọjẹ kọọkan ni pato.
Acid nucleic ti coronavirus tuntun tun jẹ alailẹgbẹ, ati wiwa nucleic acid jẹ wiwa ni pato ti acid nucleic ti coronavirus tuntun.Ṣaaju idanwo nucleic acid, o jẹ dandan lati gba awọn ayẹwo ti sputum koko-ọrọ, swab ọfun, omi lavage bronchoalveolar, ẹjẹ, ati bẹbẹ lọ, ati nipa idanwo awọn ayẹwo wọnyi, a le rii pe aaye atẹgun ti koko-ọrọ naa ti ni akoran pẹlu kokoro arun.Wiwa acid nucleic tuntun ti coronavirus jẹ igbagbogbo lo fun wiwa ayẹwo swab ọfun.Ayẹwo naa ti pin ati di mimọ, ati pe o ṣee ṣe coronavirus nucleic acid tuntun ti o ṣee ṣe lati inu rẹ, ati awọn igbaradi fun idanwo naa ti ṣetan.

Wiwa acid nucleic tuntun ti coronavirus ni akọkọ nlo imọ-ẹrọ pipo fluorescence RT-PCR, eyiti o jẹ apapọ ti imọ-ẹrọ pipo PCR fluorescence ati imọ-ẹrọ RT-PCR.Ninu ilana wiwa, imọ-ẹrọ RT-PCR ni a lo lati yiyipada acid nucleic (RNA) ti coronavirus tuntun sinu deoxyribonucleic acid (DNA) ti o baamu;lẹhinna imọ-ẹrọ PCR pipo fluorescence jẹ lilo lati ṣe ẹda DNA ti o gba ni titobi nla.DNA ti o tun ṣe ni a rii ati ṣe aami pẹlu iwadii ibalopọ kan.Ti acid nucleic coronavirus tuntun ba wa, ohun elo naa le rii ami ifihan Fuluorisenti, ati pe, bi DNA ti n tẹsiwaju lati ṣe ẹda, ifihan agbara fluorescent tẹsiwaju lati pọ si, nitorinaa aiṣe-taara wiwa wiwa ti coronavirus tuntun.
