Description
To the Editor: Fetal DNA sequences are present in the plasma of pregnant women (1) and can be studied to determine fetal sex (1) and RhD type (2). Unlike fetal cells, fetal cell-free DNA is cleared rapidly from plasma after delivery (3), with a half-life of 16-28 min. Even when clearance is slowed, as in preeclampsia (4), the mean half-life for clearance of fetal DNA is 114 min (5).
