[Comparative study of radioimmunologic and immunoenzyme methods for the determination of alpha feto-protein]

Estimation of alpha-protein (AFP) in human serum using three types of immunoenzymatic kits has given similar results. A comparative study concerning 60 sera has shown statistically significant correlations between enzyme immunoassays and radioimmunoassay (RIA): r = 0,98, p less than 10(-6). AFP estimations by EIA and RIA seem to be equally used.
