PGT-A (preimplantation genetic testing)

PGT-A (preimplantation genetic testing for aneuploidy) is an optional test that checks whether an embryo has the expected number of chromosomes before it is transferred.

A note on evidence

PGT-A is often offered as an add-on, but high-quality evidence that it improves the chance of a baby for most patients is limited. It is worth weighing the benefits, drawbacks, and cost for your situation. See questions to ask your clinic.
