What Does This Test Measure?

This test analyzes several genes—specific DNA sequences—from your blood sample. It looks for variations (mutations or changes) that could increase your risk for conditions like metabolic disorders, cancer predispositions, or neurological issues. The test may also assess carrier status for recessive genetic disorders.

Why Might You Need This Test?

Your healthcare provider may recommend this test if you have a family history of genetic disorders, if you’re considering pregnancy and want to know if you’re a carrier of certain conditions, or if symptoms suggest a genetic basis for your health concerns.

How Is the Sample Collected?

A blood sample is drawn from a vein in your arm, similar to other blood tests. The sample is processed to extract DNA for genetic analysis.

What Are Common Conditions This Test Might Detect?

This test can help identify risks for a wide range of conditions, including but not limited to: hereditary metabolic disorders (e.g., cystic fibrosis, Tay-Sachs disease), cancer susceptibility genes (e.g., BRCA1/2), and neurological disorders (e.g., Huntington’s disease). Results may also indicate carrier status for conditions that typically appear in offspring.

Frequently asked questions

How long will it take to get my results?
Results from this test typically take several weeks to months, depending on the number of genes analyzed and the laboratory’s processing timeline. Your healthcare provider will coordinate follow-up care based on the findings.
What if my test results are positive for a genetic condition?
If your results indicate an increased risk or confirmed diagnosis of a genetic condition, your healthcare provider will work with you to discuss next steps, which may include genetic counseling, lifestyle adjustments, or monitoring. Some conditions may require specialized treatment or management plans.
Can this test be used for prenatal screening?
While this test can provide information about inherited genetic risks, it is not a prenatal test. For prenatal screening, additional tests like amniocentesis or chorionic villus sampling (CVS) may be recommended if you are pregnant and have concerns about genetic conditions in your baby.
