Genetic Testing

Introducing Sema4, formerly the Mount Sinai Genetic Testing Lab at the Icahn School of Medicine at Mount Sinai. Sema4 is an innovative health information company dedicated to empowering healthier living through data.


We are an interdisciplinary partnership of scientists, doctors, engineers, clinicians, and genetic counselors. With a strong foundation of more than 160 years of clinical experience, world-class academic research, and pioneering information science, we are uniquely positioned to drive innovation in health.

Sema4 will build on the success of the Mount Sinai Genetic Testing Lab and continue to offer high quality tests for patients. This includes its Expanded Carrier Screen (formerly NextStep), which tests prospective parents for 281 genetic diseases with unprecedented accuracy by utilizing six different testing technologies. Sema4's testing menu will be quickly expanded to include non-invasive prenatal testing (NIPT), newborn screening, and oncology testing.
