What This Test Measures

The test analyzes DNA from your blood to detect known mutations in specific genes. These mutations may be associated with inherited conditions, cancer predispositions, or other genetic disorders. The test may also screen for variants of uncertain significance (VUS), which require further evaluation.

Why It’s Ordered

Your healthcare provider may recommend this test if you have a family history of certain genetic conditions, symptoms suggestive of a genetic disorder, or if you’re at higher risk due to ethnicity or lifestyle factors. It can also be part of prenatal screening or carrier testing for inherited diseases.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is processed to isolate DNA, which is then analyzed for mutations. Results are typically reported as positive, negative, or variant of uncertain significance (VUS).

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to avoid certain medications or foods for a short period if instructed by your provider. Fasted or non-fasted status may not affect this test.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result indicates the presence of a known mutation linked to a specific condition. This may confirm a diagnosis, change treatment plans, or inform family members about inheritance risks. Always discuss results with your healthcare provider for personalized interpretation.
Can this test detect all genetic mutations?
No, this test only checks for mutations in the specific genes included in the panel. It cannot detect all possible genetic variations. Additional testing may be needed for broader genetic screening.
How long does it take to get results?
Results are typically available within 2–4 weeks, depending on the complexity of the test and laboratory processing times. Follow-up with your provider is recommended to discuss findings.
