Would you like to determine whether you are the biological aunt or uncle to a niece or
nephew? Are you looking to establish a paternal or maternal relationship but are unable
to obtain the required DNA samples from the mother or alleged father?
Males who need to know whether they share the same biological father or paternal line
can opt for our Y chromosome test (Y STR Male lineage test). A Y test is a good alternative
to a paternity test where the alleged father cannot be included in the test.
