Tf inonyanya kuwanikwa muplasma, avhareji yehuwandu hwayo inenge 1.20 ~ 3.25g/L. Mutsvina yevanhu vane hutano, hapana kana hunowanikwa. Kana kubuda ropa mudumbu, Tf iri muropa inoyerera ichipinda mudumbu yobuda netsvina, inowanikwa yakawanda mutsvina yevarwere vanobuda ropa mudumbu. Nokudaro, Tf yetsvina inoita basa rinokosha pakuona kubuda ropa mudumbu. Kit iyi bvunzo iri nyore, yekuona inoona Tf mutsvina yevanhu, ine kunzwisisika kwakanyanya uye hunyanzvi hwakasimba. Bvunzo iyi yakavakirwa pa high specificit double antibodies sandwich reaction principle uye gold immunochromatographic assay analysis techniques, inogona kupa mhedzisiro mukati memaminitsi gumi nemashanu.
