Non-invasive testing and determination of foetal sex: What stage are we at? Non-invasive genotyping of the sex of a foetus has revolutionised the care given to female carriers of genetic disorders linked to the X chromosome. This test is also used in other circumstances, such as in the treatment of congenital external genital organ EGO deformities or in pregnancies with congenital adrenal hyperplasia, at risk of virilisation of the female EGOs.
This test has excellent diagnostic success in the first trimester of pregnancy. This is a preview of subscription content, log in via an institution to check access. Rent this article via DeepDyve.
