About this test

Everything you need to know about Type 1 Diabetes Risk Test

Type 1 diabetes is an autoimmune condition, and whether the immune system turns on the insulin-producing cells is strongly influenced by inheritance — particularly by variants in the HLA region. This test analyses ten well-studied markers (including rs2187668 and rs7454108 in the HLA region, rs689 near the insulin gene and rs2476601 in PTPN22) and combines them into a genetic risk estimate.

It is a risk test, not a diagnosis: a higher score means type 1 diabetes is more likely than average, not that it will happen, and most people with a higher score never develop it. It is most useful in families where type 1 diabetes is already present, and it can be followed with the Type 1 Diabetes Antibody home kit or the Type 1 Diabetes & Coeliac Detection Panel to check whether an immune process has begun.

Who it's for

Worth considering if

  • A parent, sibling or child with type 1 diabetes
  • Understanding risk before having children, where type 1 runs in the family
  • A related autoimmune condition such as coeliac or autoimmune thyroid disease
  • Anyone who wants to know whether to be alert to early symptoms
Important: A genetic test describes inherited likelihood, not certainty, and is not suitable for everyone. Our clinical team talks it through with you before the sample is taken and explains the result afterwards, including when a conversation with your GP or a genetics service is the right next step.

Frequently Asked

Type 1 Diabetes Risk Test — FAQs

What is the difference between this and a diabetes blood test?
Glucose and HbA1c measure your blood sugar now. This test looks at the genes you inherited and your long-term predisposition. The two answer different questions, and the Diabetes Health home kit covers the blood-sugar side.
If my score is high, what should I do?
Our clinician explains the result. The practical steps are to know the early symptoms — thirst, frequent urination, tiredness, weight loss — and, where appropriate, to check for diabetes autoantibodies, which show whether the autoimmune process is under way.
Does this test cover type 2 diabetes?
No. Type 2 diabetes has a different, largely lifestyle-related basis. The Lifestyle and Nutrition DNA Test includes a genetic type 2 diabetes risk result if that is what you are after.
How long do results take?
Genetic analysis takes longer than a routine blood test. We give you the expected turnaround at your appointment.
Where is the test done?
44 Crawford Street, London W1H 1JS — a short walk from Marylebone and Edgware Road stations. Your sample is taken at the clinic by our clinical team; you do not need to bring anything.
How long does the appointment take?
About 15 minutes. If you have booked several tests they are all done in the same visit.
Can I book several tests at once?
Yes. Use “Add to booking” on each test and then “Book” in the bar at the bottom — they go into one appointment and one payment. Home test kits are ordered separately, because they are posted to you.
How do I pay, and can I cancel?
Pay online when you book — by card or bank transfer — or at the clinic where that option is offered. You can cancel or reschedule up to 24 hours before your appointment for a full refund.
How do I get my results?
Results are released to your secure account and explained by our clinical team in a written summary, with a call where something needs talking through. Turnaround depends on the test: routine blood panels are quicker than genetic or DNA analysis, and we tell you what to expect at your appointment.
