What This Test Measures

The test analyzes DNA samples from your blood to detect specific gene variants (mutations) associated with hereditary conditions. These mutations may not cause symptoms now but could raise your risk for diseases later in life.

Why It Might Be Ordered

Your doctor may recommend this test if you have a family history of certain cancers, a personal history of cancer, or if you’re part of a genetic counseling program. It helps guide prevention, monitoring, or treatment plans.

How the Test Works

A small blood sample is taken to extract DNA. Specialized lab equipment (GeneChip technology) compares your DNA to known genetic sequences to identify any mutations linked to hereditary conditions.

What to Expect Before the Test

No special preparation is needed, but you may be asked to fast or avoid certain medications before your blood draw. Bring any relevant medical records or family history details to your appointment.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Will I need to take any special steps after the test results come back?
Yes, your doctor will discuss the results with you, including any increased risk for hereditary conditions. They may recommend genetic counseling, lifestyle adjustments, or further testing based on your findings.
How long does it take to get the results?
Results typically take 4 to 8 weeks or longer, depending on the complexity of the genetic analysis and your healthcare provider’s workflow. Your doctor will contact you once they’re ready to share them.
Can I refuse this test if I’m uncomfortable?
Yes, you have the right to refuse this test. Always discuss your concerns with your doctor before proceeding, as they can provide guidance tailored to your situation.
