Non-Invasive Prenatal Testing (NIPT) at 10 weeks is highly accurate, with a detection rate of over 99% for certain chromosomal abnormalities like Down syndrome, Edwards syndrome, and Patau syndrome. For determining the sex of the baby, NIPT is also very accurate, usually around 98-99%. However, it's important to discuss the results and their implications with a healthcare provider, as NIPT is a screening, not a diagnostic test.

- How reliable is NIPT for detecting Down syndrome at 10 weeks? NIPT at 10 weeks has a detection accuracy of over 99% for Down syndrome, making it a highly reliable screening option early in pregnancy.
- Can NIPT accurately determine the baby’s sex at 10 weeks? Yes, NIPT can determine the baby’s sex with about 98-99% accuracy starting from 10 weeks of pregnancy.
