What This Test Measures

The test analyzes DNA from your blood sample to detect specific genetic variations (mutations) that may be associated with inherited conditions. It uses advanced sequencing technology to identify changes in your genetic code that could influence how your body functions or increases your risk for certain diseases.

Why It’s Ordered

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 due to ethnicity or other factors. It can also be used for prenatal screening, carrier testing, or before certain surgeries or treatments.

Sample Collection and Preparation

A small blood sample is drawn from your arm. The blood is processed to isolate DNA, which is then sent to a lab for sequencing. Results are typically reported as a list of detected mutations, their locations in your genes, and their potential clinical significance.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to avoid certain medications (like blood thinners) or fasting, depending on your provider’s instructions. Bring a list of all medications and supplements you take.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Genetic mutations detected in this test can confirm or rule out inherited conditions, guide treatment decisions, or inform family planning. Some mutations may be harmless, while others could indicate a higher risk for diseases like cystic fibrosis, sickle cell anemia, or certain cancers. Results are interpreted by a genetic counselor or specialist to assess risk and implications for you and your family.

Frequently asked questions

How long does it take to get results?
Results typically take 2–4 weeks, depending on the complexity of the sequencing and lab workload. Your healthcare provider will contact you once results are ready, but delays can occur.
What does a positive result mean?
A positive result means the test identified a mutation linked to a known genetic condition. This doesn’t always mean you’ll develop symptoms—some mutations are benign or only affect carriers. Your provider will discuss the implications based on your medical history and family background.
Can I get my results in writing?
Yes, your healthcare provider or genetic counselor will explain the results in detail and provide a written report. If you’d like, they can also share a summary of key findings with you.
