Genomic DNA from peripheral blood—qualitative probe-based assay for detection of specific nucleotide variations (e.g., single nucleotide polymorphisms or small insertions/deletions)
This test checks for certain genetic variations in your blood using a small sample of DNA. It helps identify specific genetic markers that may be linked to certain health conditions or traits.

What This Test Measures
The test analyzes a specific segment of your DNA extracted from white blood cells in your blood sample. It uses a probe-based method to detect predefined genetic changes, such as single nucleotide polymorphisms (SNPs) or small genetic mutations. These changes may be associated with inherited traits or conditions.
How the Test Works
Your blood sample is processed to isolate DNA. The lab then applies a specialized probe designed to bind to specific DNA sequences. If the probe matches a genetic variation of interest, it triggers a detectable signal, confirming the presence of that variation.
Why It Might Be Ordered
Healthcare providers may order this test to assess genetic risk factors for conditions like certain cancers, cardiovascular diseases, metabolic disorders, or inherited disorders. It can also be used in research, genetic counseling, or personalized medicine scenarios.
What to Expect Before the Test
No special preparation is typically needed. You may be asked to fast or avoid certain medications, but this depends on the clinical reason for the test. Bring any relevant medical history or previous genetic test results to your appointment.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Genetic variations detected by this test may indicate an increased or decreased risk for specific health conditions. While some variations are common and may not cause issues, others could warrant further medical evaluation, lifestyle adjustments, or monitoring. Results should always be interpreted by a healthcare provider in the context of your overall health and medical history.
