How accurate is PGD testing?
Data reveals that PGD is 99% accurate in determining gender at embryonic level of day 3. However, it is to be kept in mind that there is a 1% chance of failure. In addition to this, there is a rare chance that all embryos may be of same gender hence, no scope for selection. As far as genetic abnormalities are concerned, PGD is shows up to 98% accuracy.
