Cal i heterodimer, inoumbwa neMRP 8 neMRP 14. Inowanikwa mu neutrophils cytoplasm uye inoonekwa pa mononuclear cell membranes. Cal i acute phase proteins, ine acute phase phase inokwana vhiki imwe chete mutsvina yevanhu, yakaonekwa sechiratidzo chezvirwere zvemudumbu. Kit iyi i test iri nyore, inoonekwa se semiqualitative iyo inoona cal mutsvina yevanhu, ine high detection sensitivity uye strong specificity. Iyo bvunzo yakavakirwa pa high specificit double antibodies sandwich reaction principle uye gold immunochromatographic assay analysis techniques, inogona kupa mhedzisiro mukati memaminitsi gumi nemashanu.
