Ukuhlolwa kwe-polymerase chain reaction (PCR) kwe-COVID-19 kuwukuhlola kwamangqamuzana ahlaziya isifanekiso sakho sokuphefumula esiphezulu, sibheka ufuzo (i-ribonucleic acid noma i-RNA) ye-SARS-CoV-2, igciwane elibangela i-COVID-19. Ososayensi basebenzisa ubuchwepheshe be-PCR ukukhulisa amanani amancane e-RNA asuka ezibonelweni abe yi-deoxyribonucleic acid (DNA), ephindwaphindwa kuze kutholakale i-SARS-CoV-2 uma ikhona. Ukuhlolwa kwe-PCR kube ukuhlolwa okujwayelekile kwegolide kokuhlonza i-COVID-19 kusukela kwagunyazwa ukusetshenziswa ngoFebhuwari 2020. Kunembile futhi kuthembekile.
