Summary of FISH analysis on post-CVS blood. Most identified cells contain an XY signal, while those not containing both a Y and an X-signal were damaged by the FISH procedure. A total of 129 embryonic NRBC were identified from the post-CVS sample. FISH efficiencies were 96% for the Y chromosome and 84% for the X-chromosome.

FISH-signal	Intact	Damaged	Total
XY	35	73	108
XX	0	0	0
Y	0	16	16
X	0	1	1
None	0	4	4
Total	35	94	129
