DNA Paternity Testing (sometimes called parentage testing) uses DNA, the biological basis of inheritance, to prove or disprove the relationship between a child and an alleged father. It is based on the fact that we inherit half of our DNA from our fathers and half from our mothers.
Mono tests include: 1  Monospot test (heterophil test). This quick screening test detects a type of antibody (heterophil antibody) that forms during certain infections. 2  EBV antibody test. For this test, a sample of blood is mixed with a substance that attaches to antibodies against EBV. A series of tests can detect different types of antibodies to help determine whether you were infected recently or sometime in the past.
