And you can depend on us. We’re here to support the important work you do every day. Our advanced genetic testing technologies extend your diagnostic capabilities and technological reach through:

  • High-resolution chromosomal microarrays
  • Advanced sequencing using next-generation platforms
  • Cutting-edge automated platforms

You can trust our experience. We’ve been innovators in genetic testing since the 1970s, and we offer a comprehensive menu of over 700 genetic tests. We have experience with complex and rare cases, covering a broad spectrum of genetics areas.

QNatal® Advanced: noninvasive prenatal screening with excellent accuracy

You can also continue to rely on Quest for the latest tests and technologies, such as our state-of-the-art QNatal® Advanced noninvasive prenatal screening, developed and performed by Quest Diagnostics. QNatal® Advanced offers high-risk obstetric patients a noninvasive way to determine the risk of birth defects through a blood test. By measuring traces of fetal DNA found in maternal blood, the test can pinpoint fetal aneuploidies with excellent accuracy across all common fetal chromosomal abnormalities. QNatal® Advanced can be performed from as early as 10 weeks gestation, and it can also determine the sex of the fetus.
