Comparison of two immunoassay methods for the determination of alpha-fetoprotein in amniotic fluid

We compared two immunoassay methods for determination of alpha-fetoprotein in amniotic fluid. The two methods showed a very good correlation and this is further confirmed by the clinical study. The electroimmunoassay (rocket immunoelectrophoresis) seems suitable for a small laboratory, whereas radioimmunoassay may be a better choice for a large laboratory.
