Is brca genetic testing a simple blood test?

Easy but expensive: Testing for mutations in the brca1 gene is relatively easy; yes, the dna can come from white blood cells from a blood sample. However as of now this remains a fairly expensive test; the new supreme court decision voiding the patent on the gene will probably lead to lower costs through competition but i don't think this has happened much yet.

Yes: BRCA testing can be performed from either blood or saliva. A significant amount of DNA needs to be present for adequate testing so most companies require more than a finger stick blood draw. Usually a single blood tube containing 3 ccs of blood is adequate

Simple blood test: Women w/ 2+ immediate family members w/ a hx of breast/ovarian CA at 50% chance of developing breast cancer. If you have it, get screened with CA-125 blood test, ultrasound, mammogram/MRI, usually starting at age 30. Surgery after childbearing.
