Type 1 Diabetes Risk Blood Test
A specialist blood test combining selected genetic markers and diabetes-related antibodies to help assess susceptibility to type 1 diabetes and whether further investigation or monitoring may be appropriate. Please book following clinical advice so we can confirm that this test is suitable for your medical history and family history.
What does it check?
- Genetic markers: Selected variants in the INS, ERBB3, PTPN22 and IL2RA genes associated with susceptibility to type 1 diabetes
- Diabetes-related antibodies: GAD65, IA-2, ZnT8 and insulin antibodies, which can indicate an immune response involving insulin-producing cells
Who may benefit?
This test may suit individuals with a personal or family history suggesting possible type 1 diabetes, where a specialist assessment of genetic susceptibility and autoimmune markers could help guide further investigation or monitoring.
Before your appointment
- Morning appointments only. Fasting is not normally required unless advised.
- Bring relevant previous results and details of any family history of diabetes.
- Tell us about all medicines, particularly current or previous insulin treatment, as this can affect insulin antibody interpretation.
- Do not stop prescribed medication without advice.
Results and follow-up
A clinician will review your results, explain the findings and advise on any further testing or monitoring needed. A telephone consultation with Dr Iqbal, our GP and Medical Director, is included where clinically required, at no additional charge. If specialist assessment is needed, we may advise you to contact your own GP for referral to a diabetes service. With your consent, we can share your results and a clinical summary.
£229 includes blood collection, laboratory testing, clinician review and an explanation of your results, with a GP telephone consultation where clinically required. A £25 booking deposit is deducted from the total, leaving £204 payable at your appointment. A separate initial consultation to assess symptoms or choose tests is not included. Any additional consultations, investigations or treatment will be discussed and priced before proceeding.
Please read our cancellation policy before booking.
Important information
A higher genetic risk does not mean you will definitely develop type 1 diabetes. Antibody findings require clinical interpretation and may need confirmation or further testing.
A negative result does not guarantee that diabetes will never develop. This panel does not assess type 2 diabetes risk or replace blood glucose testing when diabetes is suspected.
If you develop marked thirst, frequent urination or unexplained weight loss, seek urgent advice from your GP or NHS 111 rather than waiting for this test.
