Additional hereditary cancer risk tests

Certain things make it more likely that cancers in a family are caused by a hereditary cancer syndrome, such as:

  • Many cases of the same type of cancer (especially if it is an uncommon or rare type of cancer)
  • Cancers occurring at younger ages than usual (typically cancer in someone younger than 50 years old)
  • More than 1 type of cancer in a single person (such as a person with both breast and ovarian cancer)
  • Cancers occurring in both of a pair of organs (such as both eyes, both kidneys, or both breasts)
  • Cancer occurring in the sex not usually affected (such as breast cancer in a male)
  • Cancer occurring in multiple generations (such as in a parent, child, and grandchild)

Hereditary cancer genetic testing guide

Download our hereditary cancer reference guide for an overview of our tests, genes included in each test, and associated cancers (gene association based on guidelines and internal data).

Test codes may vary by location. Please contact your local laboratory for more information.

Components of panels may be ordered separately.

The CPT® codes provided are based on American Medical Association guidelines and are for informational purposes only. CPT coding is the sole responsibility of the billing party. Please direct any questions regarding coding to the payer being billed.

Helping you understand test results

We have created reports to help you and your patients better understand hereditary cancer test results.

Only a patient’s treating physician can make diagnoses, prognostic or treatment decisions based on the knowledge of the patient, history and clinical/educational experience. Quest lab testing provides information for the physician to use in helping make such decisions.
