What This Test Measures

The test looks for deletions (missing genetic material) in particular genes that may affect blood cells or contribute to inherited conditions. This is done using advanced laboratory techniques to detect variations in the number of gene copies compared to a healthy baseline.

How the Test Works

A small sample of your blood is collected and processed to extract DNA. Specialized laboratory methods identify any deletions in targeted genes, which may be linked to conditions like blood disorders or genetic syndromes.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you have a family history of blood-related genetic disorders, symptoms suggesting a genetic condition, or if you’re at risk for inherited blood-related issues.

Common Conditions Monitored

This screening may be used to assess risks for inherited conditions affecting blood function, such as certain types of anemia, bleeding disorders, or genetic syndromes with blood involvement.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a positive result mean?
A positive result indicates the presence of a genetic deletion in the tested genes, which may suggest an increased risk for inherited blood-related conditions. This finding will be discussed with your healthcare provider to determine next steps.
How often will I need this test?
The frequency depends on your medical history, symptoms, and healthcare provider’s recommendations. Some people may need this test once, while others may require follow-up testing over time.
Will this test affect my insurance coverage?
Coverage depends on your insurance plan and the reason for testing. Always check with your insurer or healthcare provider for details on what is covered.
