I-TF ikakhulukazi ikhona ku-plasma, okuqukethwe okuphakathi kumayelana ne-1.20 ~ 3.25g / l. Emalondolozweni aphilile, cishe abukho ubukhona. Lapho i-digetive tracting yo ukopha, i-tf e-serum ingena epheshana lesisu futhi ligcwele amalondolo, ligcwele amalondolo eziguli ezisopha olwandle. Ngakho-ke, i-FF ye-FF idlala indima edingekayo nebalulekile yokutholwa kokopha kwesisu. I-KIT iyisivivinyo esilula, esibonakalayo esibonakalayo esithola i-TF kuma-Faces antwini, inokuzwela okuphezulu nokucaciswa okuqinile. Ukuhlolwa okususelwa kuma-sandwich reaction antibodies aphezulu aphezulu kanye ne-Gold Immunochrochrographic assay ukuhlaziya ubuchwepheshe, kunganikeza umphumela kungakapheli imizuzu eyi-15.
