Brothers and sisters can carry out a sibling DNA test to establish whether they share a
common biological parent. International Biosciences UK offers accurate and reliable sibling
DNA testing services.

International Biosciences provides fast, accurate and reliable twin zygosity DNA testing to
clear up this issue that could be a deciding factor in major medical decisions such as organ
Our Grandparent DNA testing service (also called a missing parent test) will establish
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.
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.
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.
Maternity testing by International Biosciences starting from only £99 for testing mother
and 1 child. This cost includes our express turnaround time which means your results will
be ready and available to you in 3 working days from the day we receive your samples.
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.
