Relationship Testing

Quick, easy and affordable DNA tests

Are you looking to establish a relationship with certainty? International Biosciences is the DNA testing company for you, with the most up to date portfolio of testing services. We offer relationship testing for any type of relationship for which you may have doubts. We offer tests that confirm whether grandparents are related to their grandchildren, whether siblings share common biological parents and whether aunts or uncles are the real genetic relatives of their niece or nephew.

Sibling DNA Test

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

Twin Zygosity DNA Test
£139 Order now

Unsure whether your twin is identical (monozygotic), fraternal (dizygotic) or just a sibling?
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
transplants

Grandparents DNA Test

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.

Avuncular DNA Test
£199 Order now

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
£199 Order now

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.

X Chromosome Test
£329 Order now

International Biosciences offer X chromosome testing between females who need to establish
whether they have the same biological father. An X test is an accurate type of relationship
test and provides a conclusive result.

Genetic Reconstruction Test
£299 Order now

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 DNA Test
£99 Order now

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.

Mitochondrial DNA Test
£299 Order now

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.

Cousin DNA Test
Price on request Order now

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.
