Timely Diabetes Care Demands a New Approach to Testing

Timely Diabetes Care Demands a New Approach to Testing


50% of adults living with diabetes remain undiagnosed. 

Given the significant population health implications of missed or delayed detection, an immediate step-change is required in how we test for diabetes.

Digostics offers the world's first and only alternative to in-clinic oral glucose tolerance testing (OGTT) by enabling this crucial diabetes test to be performed at home.

Simplified testing.  Increased patient throughput.  Better outcomes. 

"Diabetes is Spiralling Out of Control"

International Diabetes Federation, 2022

We cannot afford for diabetes to continue to go so dangerously undetected within our communities.

Fortunately, Digostics is here to help.

The Future of Diabetes Detection, Today

Revolutionising Diabetes Testing

The OGTT remains the gold standard in diabetes testing.  However, the test takes over two hours to perform.  Furthermore, the complexity involved means it is only offered in clinics.

The inconvenience of clinic OGTT for patients and the provisioning challenges posed for healthcare professionals are significant reasons why total patient testing volumes consistently fall short of targets in standard of care.

It’s time for something different.

GTT@home is a revolutionary new OGTT home-testing service from Digostics comprised of a simple-to-use device that enables diabetes testing on a date and at a location of the patient's choosing.

Let's take the test to the patient.

Easier Diabetes Testing for Everyone


Improving Access to OGTT

Everyone should have timely and convenient access to OGTT.

And yet, late or missed tests are common as in-clinic OGTT becomes increasingly difficult to schedule, deliver and attend.

GTT@home empowers healthcare providers to offer OGTT to those who need it, when they need it.  And without concern as to how the associated test workload will be managed.

Similarly, patients get to test safely from home, with minimal disruption to daily routines and with the ability to have their results sent immediately to those responsible for their care.

A win-win for patients and healthcare professionals alike.

Easier Diabetes Testing for Everyone
Streamlining the OGTT Test Workflow

Streamlining the OGTT Test Workflow


Greater testing capacity. Faster diagnoses.

GTT@home ensures more patients can be easily tested, on time.

It provides clinic-equivalent test performance.  But significantly, without any of the staffing overheads, risks of sample degradation and laboratory delays that frequently impact clinic testing capacity.

By eliminating in-clinic tests, GTT@home enables more testing, faster results, and where warranted, an unparalleled opportunity for early clinical intervention.

Solution Features:

  • Proven equivalence to in-clinic OGTT

  • Universal ease of use without training

  • Preferred by patients

  • NFC technology for smartphone reading

  • Supports HL7 v2 messaging

  • HL7 FHIR compliant

  • Cyber security accreditation

  • UK and European marketing authorisation

"GTT@home has an excellent correlation and low bias compared to a reference laboratory glucose analyser, with an excellent agreement in categorisation of glucose tolerance."

Professor Steve Luzio 

Swansea University


"GTT@home improved uptake of testing in a critical patient group from 52% to 82% in a single offering."

"Detecting gestational diabetes is a national and global priority. OGTT home-testing would be a great boost to the identification and management of gestational diabetes."

Sir George Alberti

"We, and several of our leading clinical colleagues around the world, have the view that GTT@home could transform screening for glucose intolerance in T1D and become an important tool in clinical studies and in standards of care "
