What This Test Measures
The test analyzes DNA from your whole blood sample to detect known mutations in genes associated with certain hereditary disorders or cancer predispositions. Results may identify variants that require further medical evaluation or monitoring.
How the Test Works
Blood is drawn and processed to extract DNA. Advanced laboratory techniques (such as next-generation sequencing) compare your DNA sequence against a reference database to identify any mutations present.
Possible Conditions Detected
This screening may uncover mutations linked to conditions like breast, ovarian, or colorectal cancers, as well as other genetic disorders (e.g., Lynch syndrome, hereditary non-polyposis colorectal cancer). It is not a diagnostic test but a screening tool.
When This Test Might Be Ordered
Your healthcare provider may recommend this test if you have a family history of certain cancers or genetic disorders, or if you are at increased risk due to ethnicity or other factors.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Positive results may indicate an increased risk of developing certain conditions, prompting further diagnostic testing or genetic counseling. Negative results suggest no detected mutations in the tested genes, but they do not rule out other genetic factors. Always discuss results with your healthcare team.
