Twin Zygosity Testing – identical or non-identical?

The definitive way to determine if twins are identical or non-identical (also known as ‘fraternal’ twins) is to carry out a twin DNA test, commonly known as a Zygosity test.

We will issue a twin DNA kit and there is no need for any parental involvement. A simple cheek cell sample from each of the twins will give our laboratory all we need to provide you the answer. All processing from the beginning of your order to the end is performed in our UK based laboratory. We will never send your samples abroad or to any other company for processing meaning the result can be provided to you sooner!

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.
