Molecular Biology Report for Pathogenic Variant Detection (e.g., BRCA1/2, CFTR, or other gene-specific testing)

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have a family history of certain diseases, symptoms that suggest a genetic condition, or if you’re at higher risk due to ethnicity or other factors. It’s also sometimes used as part of a preconception or prenatal evaluation.

What to Expect Before the Test

You’ll typically provide a blood sample, which is usually drawn from your arm in a clinic or lab. No special preparation is needed, but let your provider know about any medications you’re taking.

What the Test Measures

The test looks for specific genetic mutations (changes in DNA) in one or more genes. For example, it might check for mutations in BRCA1/2 genes (linked to breast/ovarian cancer) or CFTR genes (linked to cystic fibrosis). Results are reported as either ‘positive’ (mutation found) or ‘negative’ (mutation not found).

How Results Are Interpreted

Results are reviewed by a medical professional (often a genetic counselor) who considers your family history, symptoms, and other test results. A positive result means you carry the mutation, which may influence your healthcare decisions or risk management.
