Could a simple Finger-Prick replace the dreaded diabetes test for kids?
NCT ID NCT06815081
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study from the University of Oxford is testing whether a finger-prick blood test, done at home, can replace the standard oral glucose tolerance test (OGTT) for diagnosing type 1 and type 2 diabetes in children and young people. The standard OGTT requires a vein drip and multiple blood samples over hours, which is uncomfortable. The researchers will also explore using a continuous glucose monitor as an alternative. The study involves 135 participants and aims to see if the home test is accurate and acceptable for routine care.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- finger-prick glucose test and continuous glucose monitor
- What this could lead to
- If successful, this could make diabetes testing easier and more comfortable for children, allowing early diagnosis at home instead of in a clinic.
- What could go wrong
- This is a small, early feasibility study (135 participants) focused on accuracy and acceptability, not on treatment. The home test may not match the precision of the standard venous test.

Who is studied
Cohort 1 - Children \< 18 years of age. To get a spread of glucose values, we will aim to recruit approximately equal numbers of participants with normoglycaemia, dysglycaemia and hyperglycaemia. Cohort 1 CGM sub-study - Children \< 18 years of age, who have T1D stage 1, 2 or 3 and undergoing an OGTT in cohort 1.This sub-study will be additional and optional to cohort 1. Cohort 2 - Children \< 18 years of age, who are identified as having stage 1, 2 or 3 T1D will be invited to take part in an OGTT at home. Cohort 3 - Children \< 18 years of age, who are identified as having pre-T2D. Qualitative sub-study - Young people ≥ 15 years old with T1D stage 1, 2 or recent stage 3 (up to 12 months), who have been involved in metabolic follow-up, will be invited to take part. Parents of a child (of any age) with T1D stage 1, 2 or recent stage 3 will also be invited. Healthcare professionals involved in delivering metabolic follow-up for children with diabetes antibodies will also be invited.
