Methods Monoclonal antibody against the glycophorin A was used to identify nucleated erythrocytes in the peripheral blood of pregnant women.Candidates fetal cells from 3 pregnancies at 16 to 24 weeks of gestation were isolated successfully.Sorted cells were also confirmed using Y-special probe (PY3.4) repeated sequences in maternal blood from women carrying male fetuses were detected by polymerase chain reaction.Results The PY3.4 position hybridization rates were 31.5%,0 and 38% respectively in sorted GPA positive cells of 3 samples by FISH,and the results of GPA+ cells of the 3 cases by PCR were positive,negative and positive respectively,which were manifested by the gender after aborticide.
