How reliable are PGD results?

Generally, PGD results are 95 to 98% accurate. In other words, there is a 2 to 5% chance that PGD results may be inaccurate. The reliability percentage of the diagnostic method may be higher or lower for certain couples.

If a female becomes pregnant following IVF/PGD, she will be offered chorionic villus sampling or an amniotic fluid test.
