Brief Summary:
The aim of this research is to assess the practicalities and potential benefits of collecting home finger prick samples from all patients within a hospital type 1 diabetes service to test how much insulin each patient is producing. To do this we will send detailed study information, sample collection kits and reply-paid return packs to 1500 randomly selected patients, treated as type 1 diabetes, in a hospital clinic (3000 patients in the whole clinic). We will ask participants to consent to take part (either online or by completing a paper consent form returned with their pack) before collecting a finger prick blood sample. We will ask participants to collect the sample between 1 and 5 hours after a meal and to check and record their blood glucose level at the same time. Participants will then return the sample and glucose result, using the pre-paid pack provided, to the hospital clinic laboratory for a test called C-peptide (a measure of how much of their own insulin they are producing). The sample collection process should take no longer than 10 minutes.
We will record the percentage of patients returning samples within 4 weeks of initial contact and determine the number of cases with high C-peptide suggestive of non-type 1 diabetes. If this study shows remote C-peptide testing is a practical and acceptable to patients, it could allow this remote service to be offered to all type 1 diabetes clinics in every hospital in the United Kingdom. An estimated 350,000 people in the United Kingdom have type 1 diabetes. Reclassifying an estimated 1 in 15 people would mean approximately 23,000 people nationally could benefit from being identified as potentially able to stop insulin treatment.

Detailed Description:
Background It can be hard to diagnose type 1 diabetes in adults because the symptoms can overlap with type 2 diabetes and misclassification of type 2 and type 1 diabetes can occur. This matters as type 2 diabetes cases misclassified as having type 1 diabetes potentially receive a lifetime of unnecessary insulin treatment without access to the effective treatment strategies for type 2 diabetes. Whether someone needs treating as type 1 diabetes can be confirmed by measuring their insulin levels using a test called C-peptide. This should be measured when diabetes is longstanding (over 3 years diabetes duration) as, at diagnosis levels of insulin secretion can overlap in type 1 and type 2 diabetes. A study in Scotland measured C-peptide in a clinic of patients with long standing treatment as type 1 diabetes showing around 1 in 15 of cases did not have type 1 diabetes.
As a result, in Scotland all those with longstanding type 1 diabetes now have C-peptide measured and this is likely to be recommended across the UK. For newly diagnosed cases this will occur prospectively as part of patients' ongoing type 1 diabetes care. However, for existing cases, each hospital will need to test C-peptide, on a blood sample collected from a vein, in all patients in their type 1 diabetes clinic. In addition to the burden on clinical staff to collect the samples, this C-peptide test is not measured in many UK laboratories so co-ordinating this testing on all patients within a clinic will be extremely challenging.
We have recently validated a method of testing C-peptide on capillary blood (finger prick) samples. Importantly these can be collected by a patient at their home and can be posted back to any UK laboratory where C-peptide measurement is available. Using this approach means that clinic visits for blood collection are not required and testing can be co-ordinated from a central location, making organising testing in a whole clinic much more straightforward.
