Next-generation sequencing is commonly used for embryo genetic testing, primarily targeting chromosomal abnormalities, but it is not whole genome sequencing.

“So, it's evolved over time and I should say it's still very controversial because there's always a risk of harming the embryos. You're only looking at a few cells. So, is it really representative of the embryo? I mean we do it a lot and the data definitely shows that if you transfer a normal embryo it has a very high chance of implanting but the issue is recently has been are we discarding embryos that are maybe normal uh because we think they're abnormal based on the genetic testing but the genetic testing is flawed. It's a whole So presumably genetic testing is really easy to identify annuployy that's chromosomeal analysis is trivial it's geared up to do that right okay right so most of the time we're using something called next generation sequencing which is you know very high level sequencing but it's not whole genome sequencing so you're getting targeted yeah and you're looking mostly at chromosomeal abnormalities unless you know that the couple's a carrier for some genetic mutation that”
