HelpTest Code BRTP Rapid Hereditary Breast Cancer Treatment Decision Panel, Varies
Ordering Guidance
This test is for patients diagnosed with cancer for whom results may impact treatment. A rapid turnaround time supports surgical and management decision making. For patients with cancer who do not need rapid results, order BRGYP / Hereditary Breast/Gynecologic Cancer Panel, Varies or COMCP / Common Hereditary Cancer Panel, Varies, depending on the patient’s personal and family history.
This test is not appropriate for patients who do not have cancer. If testing is needed based on a previous diagnosis of cancer or family history of cancer, order either BRGYP / Hereditary Breast/Gynecologic Cancer Panel, Varies or COMCP / Hereditary Common Cancer Panel, Varies, depending on the patient’s personal and family history.
Targeted testing for familial variants (also called site-specific or known variants testing) is available for the genes on this panel. For more information see FMTT / Familial Variant, Targeted Testing, Varies. To obtain more information about this testing option, call 800-533-1710.
Testing minors for adult-onset predisposition syndromes is discouraged by the American Academy of Pediatrics, the American College of Medical Genetics and Genomics, and the National Society of Genetic Counselors.

Useful For
Establishing a diagnosis of a hereditary breast cancer syndrome allowing for surgical and management decision making
Determining therapeutic eligibility with poly (adenosine diphosphate-ribose) polymerase inhibitors based on certain gene alterations (eg, BRCA1, BRCA2) in selected tumor types
Evaluating patients with breast cancer who have a personal history suggestive of a hereditary breast or gynecological cancer syndrome
Identifying genetic variants associated with increased risk for breast cancer, allowing for predictive testing and appropriate screening of at-risk family members
