Table 3.

Summary of the STR results for the captured fetal cells (fnRBC and/or EVT) from the 5 pregnant women. For each case, at least 4 informative STR loci are feasible to distinguish the fetal cells from the maternal cells (the non-maternal alleles are marked in bold)

Locus	Case 1 (Trisomy 13)		Case 2 (Trisomy 18)				Case 3 (Trisomy 21)			Case 4 (Disomy: 46,XY)		Case 5 (Disomy: 46,XX)
