FamilySearch does not sell DNA tests.
Are you looking for a mitochondrial DNA test? The mitochondria is passed down from mother to child. Men can take this test. There's no female-only test that I'm aware of.
Mitochondrial DNA is useful only in very specific and particular situations. If you would like to buy one, the only company that sells them is Familytreedna.com
