Ukuhlolwa Okusheshayo kwe-SARS-CoV-2 Antigen (Colloidal Gold) kuhloswe ukuthola i-SARS-CoV-2 Antigen (i-Nucleocapsid protein) kumasampula e-nasal swab in vitro. Imiphumela emihle ikhombisa ukuthi kukhona i-SARS-CoV-2 antigen. Kufanele ihlolwe ngokuhlanganisa umlando wesiguli kanye nolunye ulwazi lokuxilonga[1]. Imiphumela emihle ayikukhiphi ukutheleleka ngamagciwane noma olunye ukutheleleka ngamagciwane. Amagciwane atholakele akuzona ngempela imbangela eyinhloko yezimpawu zesifo. Imiphumela emibi ayikukhiphi ukutheleleka kwe-SARS-CoV-2, futhi akufanele kube yisona kuphela isisekelo sokwelashwa noma izinqumo zokuphatha isiguli (kufaka phakathi izinqumo zokulawula ukutheleleka). Naka umlando wakamuva wokuxhumana wesiguli, umlando wezokwelapha kanye nezimpawu ezifanayo ze-COVID-19, uma kudingeka, kunconywa ukuqinisekisa lawa masampula ngokuhlolwa kwe-PCR ukuze kuphathwe isiguli. Kungabasebenzi belabhoratri abathole isiqondiso sobungcweti noma ukuqeqeshwa futhi abanolwazi lobuchwepheshe lokuxilongwa in vitro, kanye nabasebenzi abafanele abathole ukuqeqeshwa kokulawula ukutheleleka noma ubuhlengikazi[2].
