If you wanted to book a Twin Test at a clinic, the cost would be £200 for 2 siblings. Or, if you wanted to test an extra child, for example triplets, this would increase the cost by £50.

If you choose this option, the prices for a Twin DNA Test would be as follows. The cost for 2 siblings is £230. The extra cost to have another child tested is £50.


DNA Twin Test Kits

If you prefer to take your own DNA mouth swab samples, you can order a Twin Home DNA kit by calling 0800 988 7107 and speaking to Clinical Advisor. The cost of the kit is £20, and the test analysis is £165.

To have an extra person (child) tested for any of the above options is only £45
