[Radioimmunologic assay of alpha-fetoprotein in various normal and pathological conditions].
AFP can be measured by radioimmunoassay in 52 hours using an incubation at 18 degrees C for 48 hours and the double antibody solid phase method to separate the free labelled AFP from the labelled AFP bound to the antibodies. In these conditions, the sensitivity and precision of the assay are very satisfactory and the results are directly in correlation with the results obtained using the classical double antibody method. In the serum of normal people, except pregnant women, the concentration of AFP is not detectable or is less than 20 ng/ml. In the serum of pregnant women, AFP increases from the 8th. week of gestation to the 32nd., then stabilises or gradually decreases.
