General Information About the Test
Test Process and Preparation
Yes. Healthy individuals, particularly those with a family history of early-onset breast cancer (BRCA genes) or colon cancer, can find out if they carry these genetic mutations by giving blood and taking preventive measures.
In clinical genetics, a blood sample drawn from the arm is most commonly used. However, depending on the situation, the test can also be performed by isolating DNA from saliva, a cheek swab, tumor tissue taken via biopsy, or amniotic fluid for a baby in the womb.
Depending on the size and scope of the gene to be examined (single gene analysis or whole exome sequencing), getting the results can take between 2 weeks and 1 month because DNA sequencing processes are quite arduous.
