Prenatal genetic testing to identify hereditary conditions

For expectant parents, who value their baby’s well-being above all else, prenatal testing can provide critical insights on their child’s health. Our full menu of clinically supported prenatal testing enables results that patients and physicians can depend on.

Featuring carrier screening options and diagnostic testing, our offerings include testing for a variety of genetic conditions, including known familial variants. We also offer cytogenetic analysis options such as karyotype, targeted fluorescent in situ hybridization (FISH), and microarray to evaluate for chromosomal aneuploidy and microdeletion/microduplication syndromes.

Commitment to care

At Mayo Clinic Laboratories, our meticulous care of prenatal samples throughout all laboratory processes ensures all appropriate testing can be completed. From careful handling of specimens upon receipt to expeditious reporting of clinically relevant results, we are dedicated to providing unmatched service to physicians and their patients. Key benefits of our testing include:

  • Access to experienced genetic counselors who specialize in prenatal testing for ordering guidance, case review and management, and result interpretation assistance.
  • Reflex of prenatal microarray testing to limited chromosome or FISH testing to structurally characterize abnormal findings as needed.
  • A robust test menu with prenatal diagnostic testing available for a wide variety of conditions.
