We recommend both partners consider screening to have the most accurate risk assessment for genetic conditions. Screening only one one partner still significantly reduces a couple’s shared risk, but provides a less complete picture.
That’s because, while our test is highly accurate, no genetic test has a 100% detection rate. Furthermore, there are conditions for which we do not or cannot test. Even if one partner screens negative for certain disorders, risks of genetic disorders can never be completely eliminated.
Additionally, it is faster to screen both partners at the same time, rather than waiting for one partner’s results before starting the process a second time for the other partner.
