whether you are really the biological grandparents of your grandchild or grandchildren.
Your DNA test results are ready in 5-7 working days from the receipt of your samples.

Avuncular DNA Test

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?

Y Chromosome Test

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.

A genetic reconstruction test is used as an alternative to DNA paternity
testing and is often used when the alleged father of a child or children is
deceased, unavailable or unwilling to be tested.

A cousin DNA test seeks to establish whether first degree cousins are biologically related.
We receive many requests for cousin testing but does not currently offer it, as results are often inconclusive.

Mitochondrial DNA Test

Do you share a common maternal ancestor? Do you perhaps have the same mother,
grandmother or great grandmother? If you need to have these questions answered,
an X-SV female lineage test could be the ideal test for you.
