Twins tests

Is there a way to find out if your twins are identical or not? Yes, there is: our DNA test will tell you the type of zygosity of your twins.

The Standard Twins Test evaluates if the twins have the same DNA profile (identical twins or monozygotic), or if they have different DNA profiles (being, therefore, non-identical twins). You only need to submit a DNA sample of each twin for this analysis.

Semi-Identical twins are a special case of non-identical twins. The Semi-Identical Twins Test evaluates if this is the type of zygosity the twins have. Of course, if the twins were identical, this test would also be able to detect it. For this analysis you need to submit a DNA sample of the twins and of both parents. You can also upgrade to this test is the standard one determines that the twins are non-identical.

These tests can also be used to determine the zygosity between triplets, quadruplets, etc. The tests will evaluate if all siblings are identical, non-identical, or if some of them are identical and others are non-identical.
