Avuncular (uncle-aunt) DNA test is a test that can be performed with biological sister or brother of alleged father instead of paternity test when alleged father cannot participate in DNA test. Before starting to perform DNA test, permissions of test participants; i.e. uncle or aunt in addition to child, must be taken. If the age of child is under 18, permissions of official parents must be taken. It is possible to take sample easily by stirring cotton swabs sent by us to inside of their cheeks. By this way, participants can take their samples on their own in an acheless and painless way. After receiving samples, they are examined and results are obtained in 7 workdays. Results cannot be used as evidence in courts.
