A process for the determination of ferritin in serum or in plasma is disclosed, which comprises incubating an antibody directed against an organ-specific isoferritin, which is covalently bound to nylon(polyamide 6,6), on the one hand with ferritin standard solutions and on the other hand with serum samples, decanting or aspirating the incubation solutions, washing the nylon-antibody-ferritin complex formed and subsequently incubating it with a iodine-labelled antibody directed against a second organ-specific isoferritin, isolating the nylon-antibody-ferritin-anti-body-125I-complex formed, counting its radioactivity in the gamma counter and comparing the standard samples with the serum samples.
