Tsopano mtundu wa XBB 1.5 ndiwopenga pakati pa dziko lapansi.Makasitomala ena amakayikira ngati mayeso athu othamanga a covid-19 antigen amatha kuzindikira izi kapena ayi.

Spike glycoprotein ilipo pamwamba pa novel coronavirus ndipo imasinthidwa mosavuta monga Alpha Variant (B.1.1.7), Beta Variant (B.1.351), Gamma Variant (P.1), Delta Variant (B.1.617), Omicron Variant (B.1.1.529), mtundu wa Omicron (XBB1.5) ndi zina zotero.
Viral nucleocapsid imapangidwa ndi mapuloteni a nucleocapsid (N protein yochepa) ndi RNA.Mapuloteni a N ndiwokhazikika, gawo lalikulu kwambiri m'mapuloteni opangidwa ndi ma virus komanso kukhudzidwa kwakukulu pakuzindikirika.
Kutengera mawonekedwe a N protein, Monoclonal antibody ya N protein motsutsana ndi buku
coronavirus idasankhidwa pakupanga ndi kupanga kwazinthu zathu zotchedwa "SARS-CoV-2 Antigen Rapid Test (Colloidal Gold)" yomwe cholinga chake ndi kuzindikira kwa SARS-CoV-2 Antigen mu zitsanzo za swab za m'mphuno mwa kuzindikira N protein.
Izi zikutanthauza kuti, mtundu waposachedwa wa spike glycoprotein mutant kuphatikiza XBB1.5 sukhudza zotsatira zoyesa.
Chifukwa chake, athuSars-Cov-2 Antigenamatha kuzindikira XBB 1.5
