What This Test Measures
The test analyzes DNA from your blood to identify particular mutations in one or more genes. These mutations may be linked to conditions such as cancer, metabolic disorders, or other genetic syndromes. The test uses advanced genetic sequencing technology to detect changes in the DNA sequence that may not be visible through traditional blood tests.
Why It Might Be Ordered
Your healthcare provider may recommend this test if you have a family history of certain genetic conditions, if you are at higher risk due to ethnicity, or if symptoms suggest a genetic disorder. It may also be used as part of prenatal screening or before certain treatments to assess genetic predispositions.
Sample Collection and Preparation
A small amount of your blood will be drawn from a vein, typically in your arm. The blood sample is then processed to extract DNA for genetic analysis. This process is usually quick and may cause a slight pinch, but it is generally well-tolerated.
What to Expect After the Test
After your sample is collected, it is sent to a laboratory for genetic testing. Results may take several days to weeks, depending on the complexity of the test and the lab’s workload. You will be contacted by your healthcare provider with the results once they are ready.
