Preimplantation diagnosis

Overview
Preimplantation diagnosis is the act of checking an ovum, zygote, or blastocyst for defects or diseases by cytogenetics before implanting into a womb. Preimplantation diagnosis takes place before prenatal diagnosis, which refers to a checking for defects in a fetus or embryo that is already in a womb. Preimplantation diagnosis spares "women from carrying a pregnancy to the first or second trimester before learning of a serious genetic abnormality."
