Natera’s gender identification test, a non-invasive prenatal screening (NIPS) option, analyzes cell-free fetal DNA circulating in the pregnant person’s blood. It seeks to identify the presence or absence of the Y chromosome, which determines biological sex. Reported accuracy rates are generally very high.
Early knowledge of fetal sex offers advantages for expectant parents, facilitating preparation and planning. This information may also be crucial in cases where sex-linked genetic disorders are a concern, allowing for earlier monitoring and potential interventions. Historically, gender determination relied on later ultrasound examinations.
