Uvavanyo olukhawulezileyo lwe-SARS-CoV-2 Antigen (Colloidal Gold) lwenzelwe ukufumanisa umgangatho we-SARS-CoV-2 Antigen (i-Nucleocapsid protein) kwiisampuli ze-nasal swab kwi-vitro. Iziphumo ezilungileyo zibonisa ukuba kukho i-SARS-CoV-2 antigen. Kufuneka ixilongwe ngakumbi ngokuhlanganisa imbali yesigulana kunye nolunye ulwazi lokuxilonga[1]. Iziphumo ezilungileyo azikhuphi usulelo lwebhaktheriya okanye olunye usulelo lwentsholongwane. Iintsholongwane ezifunyenweyo azingoyena nobangela uphambili weempawu zesifo. Iziphumo ezimbi azikhuphi usulelo lwe-SARS-CoV-2, kwaye akufuneki zibe sisiseko sonyango okanye izigqibo zolawulo lwesigulana (kubandakanya izigqibo zolawulo losulelo). Nika ingqalelo imbali yamva nje yesigulana, imbali yezonyango kunye neempawu ezifanayo ze-COVID-19, ukuba kuyimfuneko, kuyacetyiswa ukuba uqinisekise ezi sampuli ngovavanyo lwe-PCR ukuze kulawulwe isigulana. Yeyabasebenzi belabhoratri abafumene ulwalathiso lobuchwephesha okanye uqeqesho kwaye banolwazi lobuchwephesha lokuxilongwa kwi-vitro, kwanabasebenzi abafanelekileyo abafumene uqeqesho lolawulo losulelo okanye lobuhlengikazi[2].
