As of 2015, free paternity tests are available in Arizona, Alaska, Louisiana and Oklahoma to individuals who meet certain qualifications. For these eligible citizens, the state covers the cost of testing.
In Louisiana, if either biological parent receives public assistance, the state pays the testing fees. If a man takes a paternity test in Arizona, Alaska or Oklahoma and the test proves him to be the father, he must repay the testing fees. Free paternity testing kits are also available online at websites such as HomeDNA.com. However, only the test itself is free; the recipient must pay for shipping costs and the laboratory services for processing samples, which cost $150.
