title: The first clinical trial for determination of alpha 1 fetoprotein by means of Sevatest-ELISA AFP Kit (micro I).
abstract: At the Institute of Sera and Vaccines, Praha, was invented and tested on clinical samples a kit for detection and quantification of alpha 1 fetoprotein in human serum. It is a heterogeneous EIA on the "sandwich" principle. Rabbit antibody to alpha 1 fetoprotein (further AFP) was used for coating the solid surface and goat horse-radish peroxidase labelled antibody to AFP was used as the tracer. Microtitration plate of Czechoslovak manufacture (KOH-I-NOOR, Dalecín) type P with 96 wells was used as the solid phase. The range of an approximately linear part of the calibration curve was intentionally chosen between 10 and 400 ng/ml, since in this way it fills the detection gap in AFP determination between 10 and 200 ng/ml, which is, on the one hand, a physiological value of AFP in human serum and, on the other hand, the bottom limit of sensitivity of counter immunoelectrophoresis (CIEP). Attention was devoted both to reproducibility of the method, i.e. results of intra- and interassays, and comparability with other foreign ELISA Kits. According to the correlation analysis, the kit was ascertained to be very well comparable with kits of foreign provenance. The coefficient of variation (CV) for the interassays varied between 11 and 16% and for intraassays it equalled 15%.
