The TwinsUK Registry
TwinsUK is the UK’s largest ADULT twin registry with over 15,000 twins (identical and non-identical) aged 18-100. Twins have taken part in valuable health and ageing research since 1992 overseen by the Department of Twin Research. To read more about the TwinsUK click on this link.
Who Can Join?
Please do not register with us if you are not a twin. You can take part in our COVID-19 symptom tracking study if you are not twin, without registering with us. Please find more information about this here.
Any same-sexed twins, identical or non-identical, who are 18 years of age and older, living in the UK or overseas can join the registry and take part in our research programme.
Twins of different sex can join the registry and receive our updates but cannot take part in our current research programme due to the difficulties in comparing male and female twins in research.

What does participation involve?
You can choose to participate in our research in a number of ways:
- All twins are invited for a full-day twin research visit at the Department of Twin Research based at St Thomas’ Hospital in London approximately every four years. The research visit involves a number of tests such as blood tests (including a cholesterol and diabetes check, as well as DNA), bone density, blood pressure, cardiac assessments, simple fitness and sensory tests, eye tests and more. Clinically useful results are posted to participants approximately 4 to 6 weeks after the visit.
- All twins are invited to take part in postal studies.
- All twins are invited to complete questionnaires by post and/or on-line (one or two per year).
- Sub-sets of twins may be invited to participate in research focused on a specific condition/ disease.
