I-Tf itholakala kakhulu ku-plasma, okuqukethwe okumaphakathi kungaba ngu-1.20 ~ 3.25g/L. Kubantu abaphilile, indle ayibonakali. Lapho ukopha komgudu wokugaya ukudla, i-Tf esegazini igeleza iye emgodini wokugaya ukudla futhi ikhishwe nendle, itholakala kakhulu endle yeziguli eziphuma igazi esiswini. Ngakho-ke, indle i-Tf idlala indima ebalulekile ekutholeni ukopha komgudu wokugaya ukudla. Le khithi iyisivivinyo esilula nesibonakalayo esibonayo esithola i-Tf endle yabantu, sinozwela lokuthola okuphezulu kanye nokucaciswa okuqinile. Isivivinyo esisekelwe ku-high specificit double antibodies sandwich reaction principle kanye ne-gold immunochromatographic assay analysis techniques, singanikeza umphumela zingakapheli imizuzu eyi-15.
