What Does This Test Measure?

The test analyzes DNA from your blood to detect known mutations in genes associated with certain conditions. It may look for changes in genes linked to inherited disorders, cancer risks, or other genetic conditions. Results are tailored to the specific genes tested based on clinical indications.

How Is This Test Performed?

A small blood sample is drawn from your arm. The DNA is extracted from the blood cells and prepared for sequencing. Advanced laboratory techniques compare your DNA sequence against known reference sequences to identify mutations.

Your doctor may suggest this test if you have a family history of genetic conditions, symptoms suggestive of a genetic disorder, or if you are at higher risk for certain cancers or other diseases. It can also be used for prenatal screening, carrier testing, or before certain treatments.

What Are the Possible Results?

Results can be categorized as normal (no mutations detected), variant of unknown significance (a mutation whose clinical impact is unclear), or pathogenic (a mutation strongly linked to a condition). Some results may require further genetic counseling or testing.

Clinical interpretation

Frequently asked questions

What does a positive result mean?

A positive result indicates the presence of a mutation linked to a specific genetic condition. This may mean you are at higher risk for developing that condition or passing the mutation to offspring. Your healthcare provider will discuss the implications and next steps with you.

How long does it take to get results?

Results typically take 2 to 6 weeks, depending on the complexity of the test and laboratory processing times. Your healthcare provider will contact you once results are available.

Can this test be done on other samples besides blood?

While this test is primarily performed on whole blood, some genetic tests may use saliva or other samples. Always confirm with your healthcare provider which sample type is appropriate for your specific test.
