Why This Test Is Done
Your healthcare provider may order this test if you have a family history of genetic disorders, symptoms of a suspected genetic condition, or if you’re considering genetic counseling or testing for a specific condition. It can also be part of prenatal screening or carrier testing for certain inherited diseases.
What to Expect Before the Test
You’ll typically have a simple blood draw, similar to a routine blood test. No special preparation is usually needed, but your provider may ask you to fast or avoid certain medications for a short time before the procedure.
What Happens During the Test
The blood sample is collected and sent to a lab for genetic analysis. The lab will look for specific mutations in your DNA that may be linked to certain health risks or conditions. Results may take several days to weeks, depending on the complexity of the test.
What the Results Mean
Results can be normal (no mutations found), positive (mutations detected that may indicate a risk or condition), or inconclusive (further testing may be needed). Your healthcare provider will discuss the results with you in detail and explain next steps, such as additional testing or monitoring.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
