What This Test Measures

The test detects specific mutations in a gene (e.g., SCN1A) that could be associated with inherited disorders. These mutations are changes in the DNA sequence that may affect how proteins function in your body. The test looks for these changes in the DNA extracted from your blood cells.

How the Test Works

Your blood sample is collected and processed to isolate DNA. Advanced laboratory techniques, such as next-generation sequencing or targeted mutation detection, are used to analyze the DNA for the presence of known mutations in the specified gene(s).

Why It Might Be Ordered

A healthcare provider may recommend this test if you have a family history of certain genetic disorders, symptoms of a suspected genetic condition, or if you are at increased risk due to ethnicity or other factors.

What to Expect Before the Test

No special preparation is typically needed for this test. You may be asked to fast or avoid certain medications, but this depends on the specific instructions provided by your healthcare team. Bring any relevant medical records or family history details to your appointment.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Identifying these genetic mutations can help confirm a diagnosis, guide treatment decisions, or inform family planning. Early detection may allow for proactive management of symptoms or monitoring to prevent complications. Results can also help determine eligibility for clinical trials or genetic counseling services.

Frequently asked questions

What does a positive result mean?
A positive result indicates the presence of the specific mutation in your DNA. This finding may suggest an increased risk for certain inherited conditions. Your healthcare provider will discuss the implications of these results in the context of your medical history and family history.
What does a negative result mean?
A negative result means the specific mutations tested for were not found in your DNA. However, other genetic mutations or conditions not covered by this test could still be present. If you have concerns, your healthcare provider may recommend further testing or additional genetic evaluations.
How long does it take to get results?
Test results are typically available within 1 to 2 weeks, depending on the laboratory and complexity of the analysis. Your healthcare provider will contact you once the results are ready and will explain what they mean for your health.
