Targeted testing for hereditary breast and ovarian cancer syndromes
BRCAssure
BRCA1 and BRCA2 mutations account for most families with hereditary breast and ovarian cancer syndrome (HBOC),1 and the estimated lifetime risk of breast cancer in women with BRCA1 mutations is 46% to 87%; for BRCA2, the risk is 38% to 84%.2
Labcorp's BRCAssure assay
At Labcorp, we understand the importance of identifying patients with a BRCA mutation. With the analytical sensitivity and specificity of Labcorp’ BRCAssure assay, and a comprehensive suite of tests to identify BRCA mutations associated with breast and ovarian cancer, as well as other cancers, you can have confidence in the test performance and select the BRCAssure testing option that is the most appropriate for your patient based on her or his personal or family medical history.

Helping patients understand their results
Discussing BRCAssure testing results with patients can be a challenge in the short time you have to speak with them during an appointment. To help simplify the discussion, Labcorp is pleased to provide you with patient genetic eduational videos that provide information on the test result and the possible next steps, if any, that the patient should consider, including speaking with a genetic counselor.
Test Options
Full sequencing of the BRCA1/2 genes, plus deletion/duplication analysis. May be used to assess the risk of carrying a BRCA1/2 mutation when the patient’s history suggests an increased risk for hereditary breast and ovarian cancer in the absence of a known familial mutation.
Targeted analysis of the founder mutations found within the Ashkenazi Jewish population. May be used as a first line test for individuals of Ashkenazi Jewish descent; if negative the option to run a Comprehensive BRCA1/2 Analysis is available.
Targeted sequencing for specific familial or known mutations on the BRCA1 gene.
Targeted sequencing for specific familial or known mutations on the BRCA2 gene
