Testing a home method for glucose tolerance in children with Type 1 Diabetes

Official title: A Study to Determine a Capillary Alternative to the Gold Standard Oral Glucose Tolerance Test

Run by University of Oxford · NCT06815081 · Data updated 2026-11-12

This study tests a new way for kids with Type 1 Diabetes to check their blood sugar at home using a finger prick instead of a needle to see if it's easier and more comfortable.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include children under 18 years old who are undergoing an OGTT or have tested positive for islet autoantibodies.

Probably not a fit

Patients who are over 18 years old or those who cannot consume the oral glucose drink within the required time frame may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to evaluate the feasibility of conducting an oral glucose tolerance test (OGTT) at home using a finger-prick method instead of traditional venous blood draws. Participants will consume a sugary drink and have their glucose levels measured before and two hours after consumption. The study will also explore the use of continuous glucose monitors (CGMs) as an alternative method for glucose monitoring. The goal is to improve the comfort and accessibility of glucose testing for children at risk of or diagnosed with Type 1 Diabetes.

Why it matters

Potential benefit: If successful, this approach could make glucose testing more comfortable and accessible for children, potentially leading to earlier diagnosis and management of Type 1 Diabetes.

How similar studies have gone: While the concept of home glucose monitoring is gaining traction, this specific approach using a finger-prick OGTT is relatively novel and has not been extensively tested in similar studies.
