Are you pregnant, and does your baby's father have type 1 diabetes?

Are you pregnant, and does your baby's father have type 1 diabetes?

Researchers at King's College London and Guy's and St Thomas' NHS Foundation Trust are looking for pregnant people over 16 whose baby's father has type 1 diabetes to take part in a study. The study will look at whether things that happen during pregnancy, such as infections, can affect how a baby's immune system develops and their chance of developing conditions like type 1 diabetes when they're young.

Who can take part?

You may be eligible if you:

Are over 16 years of age

Are pregnant, and the father of your baby has type 1 diabetes

Have booked your antenatal appointments at St Thomas' Hospital or King's College Hospital in London

What's involved?

What's involved?

The study follows you through your pregnancy and your baby up to 2 years of age. If you decide to take part, you will be asked to:

Antenatal blood samples

Give additional blood samples when attending routine antenatal appointments at hospital.

Answer questions

Answer questions about your general health and wellbeing.

Cord blood and placenta collection

Allow us to collect cord blood and the placenta at the birth of your baby, which are usually discarded.

Postnatal blood samples

Bring your baby to the children's blood test department at St Thomas' Hospital for a small blood sample at 12 and 24 months of age.


At around 18 months, either give a blood sample at the hospital in the same way, or use a home sampling kit to take a small prick blood sample from your child and send it back.

We'll test your child's blood samples for signs that can show whether they're more likely to develop type 1 diabetes in the future.


Your usual antenatal care will continue, and you will be seen by your normal doctors and midwives.
