How do twin DNA tests work?

In the laboratory we will test the DNA samples from the twins using 23 markers to determine if they are genetically identical at all the DNA markers, or if they have similar but different DNA profiles, as is expected with full siblings (i.e non-identical twins).

This produces extremely accurate results which will conclusively determine if twins are identical or not.
