BRCA1, familial breast-ovarian cancer susceptibility 1

Diagnosis and Testing

Does it matter if you test blood vs. saliva vs biopsy for a BRCA1 gene mutation?

All genetic testing laboratories should accept blood samples and many also accept saliva samples. Saliva sample tests are just as reliable as blood sample tests. All the cells in a person's body have the same DNA, so it does not matter if you test blood cells or cells found in saliva.
