There are 5 DNA tests that actually needs to be done as reported from Menshealth:
1. DNA tests to determine the risk of prostate cancer.
DNA testing is done by analyzing five genetic variants in saliva. A study in the New England Journal of Medicine found that men with four of the five variants have an increased risk of prostate cancer is 450 percent higher than other men.
Companies that have claimed assay 99.9 percent accuracy. But its weakness, this test is no longer available after October 2008.
