NTD Laboratories

NTD Laboratories is a specialized clinical reference laboratory focused on prenatal screening and maternal-fetal medicine. The company is a leader in biochemical screening for chromosomal abnormalities, including Down syndrome (Trisomy 21), Trisomy 18, and Trisomy 13, as well as open neural tube defects. It is well-known for developing and offering proprietary screening programs like UltraScreen and FirstScreen, which integrate maternal serum markers with nuchal translucency ultrasound data. Founded on pioneering research in maternal risk assessment, the laboratory provides critical diagnostic information to healthcare providers and expectant parents. In 2005, the company was acquired by PerkinElmer to expand its global footprint in the prenatal and neonatal testing markets, and it now operates under the Revvity brand.
