What This Test Measures

The test analyzes DNA from your blood sample to detect known mutations in genes associated with certain hereditary conditions, cancer predispositions, or other genetic disorders. It may look for changes in genes like BRCA1/2 (breast/ovarian cancer), Lynch syndrome genes, or others based on clinical indication or family history.

How the Test Works

Blood is collected and processed to extract DNA. Advanced sequencing technology reads the genetic code to identify any mutations present in the targeted genes. Results are compared against a database of known mutations to determine if any are present.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you have a family history of genetic disorders, cancer, or if you’re at higher risk due to ethnicity, age, or symptoms like unexplained fatigue, skin changes, or organ dysfunction.

What to Expect Before the Test

No special preparation is needed, but you may be asked to fast or avoid certain medications for 12 hours before the blood draw. Bring a list of all medications and supplements you take.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Will this test show all possible genetic issues?
No, this test only checks for specific mutations in a limited set of genes. It’s not a comprehensive genetic test. Additional tests may be needed if other genes or conditions are suspected.
How long will I get results?
Results typically take 2–4 weeks, depending on lab processing and sequencing delays. Your provider will contact you once results are available.
Can I refuse this test?
Yes, you have the right to refuse this test. Discuss your concerns with your healthcare provider to understand the potential benefits and risks before deciding.
