What This Test Measures

The test analyzes DNA extracted from your white blood cells to detect known mutations in genes. These mutations may be associated with conditions like inherited disorders, cancer predisposition, or other genetic variations.

Why It’s Done

Your healthcare provider may recommend this test if you have a family history of genetic disorders, symptoms suggestive of a genetic condition, or if you’re at higher risk for certain cancers.

Sample Collection and Preparation

A blood sample is drawn from your arm, similar to a regular blood test. The DNA is then isolated from your white blood cells for analysis.

How Results Are Interpreted

Results are compared against known mutation databases. Positive findings may indicate an increased risk for specific conditions, while negative results suggest no detected mutations for the tested genes.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean for my health?
A positive result means the test detected a mutation in the gene(s) being checked. This could indicate an increased risk for certain conditions, but it doesn’t always mean you’ll develop them. Your healthcare provider will discuss next steps, such as monitoring, additional testing, or lifestyle recommendations.
Will this test affect my insurance or ability to get treatment?
Results from genetic tests are confidential and protected under privacy laws. Insurance coverage depends on your specific situation, policy, and the clinical need for the test. Always discuss coverage with your insurer or healthcare provider.
How long will it take to get my results?
Turnaround time varies by lab and complexity. Simple mutation screens may take weeks, while more comprehensive analyses could take months. Your provider will provide a timeline during your test order.
