Placental isoferritin (PLF) is present in serum at high concentrations
throughout normal gestation. The current study compared PLF concentrations
in first trimester maternal serum with those of amniotic and coelomic
fluids in 25 healthy, pregnant women. Use of a specific enzyme-linked
immunosorbent assay indicated concentrations high (22 +/- 3 U/ml) in
maternal serum, whereas significantly lower values were detected in both
coelomic and amniotic fluids (5 +/- 2 and 3 +/- 2 U/ml, respectively, P
< 0.005). It was further demonstrated that when pure PLF was added to
amniotic and coelomic fluids, the PLF levels remained low in each
compartment, suggesting that bioproducts produced inside the gestational
sac may interfere with the PLF immunoassay.
