Genomic DNA from whole blood (qualitative probe for specific sequence variants)
This test checks for specific genetic variations in your blood using a DNA probe. It helps identify whether certain genetic sequences are present or absent.
["This test may be used to screen for inherited conditions or confirm genetic testing results."]

What This Test Measures
The test analyzes your blood DNA for specific nucleotide sequences using a molecular probe. This probe binds to particular genetic regions, allowing detection of variations like mutations, deletions, or duplications. Results are qualitative, meaning they indicate presence or absence rather than precise amounts.
How the Test Works
A small blood sample is collected and processed to extract DNA. The probe targets a known genetic region, and detection methods (such as fluorescence or color change) confirm whether the sequence matches the expected pattern. No quantitative values are provided.
Common Uses
This test may be used for genetic screening, carrier testing for inherited disorders, or confirming mutations detected in other genetic tests. It’s often part of prenatal testing, newborn screening, or research studies.
Sample Collection
A simple blood draw is performed, similar to other blood tests. The sample is sent to a lab for DNA extraction and probe-based analysis. Results are typically available within 1–2 weeks, depending on lab processes.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
Frequently asked questions
This test helps identify genetic predispositions to diseases, such as certain cancers, metabolic disorders, or neurological conditions. Early detection can guide preventive measures or treatment planning. However, it’s important to discuss results with your healthcare provider to interpret their relevance to your health.
How long will I need to wait for results? Results are usually ready within 1–2 weeks, but timing can vary based on lab workload and follow-up testing.
Is this test covered by insurance? Coverage depends on your insurance plan, the clinical indication, and whether the test is part of a diagnostic or preventive protocol. Check with your insurer or provider for details.
