The Diabetic Profile 1 test is a blood test that evaluates current and long-term blood sugar control by measuring Glucose and HbA1c (Glycated Haemoglobin). Together, these markers provide a comprehensive overview of glucose metabolism.
Glucose reflects blood sugar levels at the time of testing, while HbA1c represents the average blood glucose level over the previous 8–12 weeks. This dual approach allows both immediate and long-term assessment of diabetes risk and control.
The profile is widely used for diagnosing diabetes, identifying prediabetes and monitoring individuals with established diabetes.
You may need this test if you are at risk of diabetes, have symptoms suggestive of high blood sugar or require routine monitoring of an existing diagnosis. Diabetes can develop gradually and remain asymptomatic until complications arise.
Early detection allows lifestyle or medical intervention to prevent or delay complications affecting the heart, kidneys, nerves and eyes.
Symptoms and scenarios where testing is recommended:
You can attend one of our UK partner clinics or arrange a home or hotel visit with a mobile phlebotomist.
Low Levels
Low glucose levels may indicate hypoglycaemia, often related to medication, fasting or metabolic conditions.
Low HbA1c suggests consistently low average blood sugar.
Typical UK reference guidance:
Normal Levels
Normal glucose and HbA1c levels indicate healthy blood sugar regulation and low diabetes risk.
Typical UK reference ranges:
High Levels
Elevated glucose or HbA1c suggests impaired glucose tolerance, prediabetes or diabetes.
Persistent high levels increase the risk of long-term complications.
Typical UK reference guidance:
Reference ranges may vary slightly by laboratory.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
