What Does This Test Measure?

This test detects particular genetic mutations or variations in your DNA present in your blood cells. It focuses on variants that may be linked to conditions like metabolic disorders, blood disorders, or cancer predispositions. The test is not a general genetic screen but is tailored to specific variants of interest for your clinical situation.

Why Might You Need This Test?

Your healthcare provider may recommend this test if you have a family history of certain genetic conditions, if you’re at risk for inherited disorders, or if symptoms suggest a genetic basis for your health concerns. It can also be used to confirm or rule out suspected genetic conditions in diagnostic workups.

How Is the Test Performed?

A small blood sample is drawn from your arm. The sample is then analyzed in a laboratory to identify specific genetic variants. The test may involve advanced molecular techniques such as sequencing or targeted next-generation sequencing to detect these variations accurately.

What Are the Possible Results?

Results will indicate whether the detected genetic variants are classified as benign (not clinically significant), likely benign, variants of uncertain significance (VUS), or clinically significant (linked to increased risk or disease). Some results may require further evaluation or follow-up testing.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What Does a Positive or Negative Result Mean?
A positive result for a clinically significant variant means the variant may increase your risk for a specific condition. This does not mean you will definitely develop the condition, but it may prompt additional testing, monitoring, or preventive measures. A negative result means no clinically significant variants were found in this test, but other genetic tests or evaluations may still be needed.
Will This Test Show All Genetic Conditions?
No, this test only checks for specific genetic variants that have been selected for your situation. It does not screen for all possible genetic conditions. Additional genetic tests may be recommended depending on your symptoms, family history, or clinical needs.
How Often Should I Get This Test?
The frequency of this test depends on your healthcare provider’s recommendations. Some individuals may need this test once, while others may require follow-up testing based on ongoing health concerns or family history.
