How DNA test pricing works

DNA test pricing is based on the number of people included in the test and the type of family relationship being analysed. Each test option has a fixed price, which is clearly shown before checkout.

For paternity DNA testing, the test price increases only when additional children or alleged fathers are included. Where available, the mother can be included at no additional cost to help improve result confidence.

For sibling and grandparent DNA tests, pricing reflects the number of individuals tested. One known parent is included free of charge, and all sibling and grandparent tests use 45 DNA markers to provide enhanced accuracy for extended family relationship analysis.

To make testing more accessible, we offer flexible payment options, including the ability to split costs and use pay-later services such as Klarna, Shop Pay Installments and PayPal Pay Later (where eligible).
