Diabetic Profile 1 checks your current blood sugar alongside your average blood sugar control over the past two to three months, giving a simple first look at how your body is managing glucose. It suits anyone with symptoms such as increased thirst or tiredness, a family history of diabetes, or those wanting a routine check. The profile costs £83.75 plus a £50 blood-draw fee, with results back in 1 day. You can walk in or book online at 117a Harley Street, seven days a week, with no GP referral needed.
This profile is often requested when someone has symptoms that could suggest diabetes, such as increased thirst, needing the toilet more often, unexplained tiredness or unexpected weight change.
It's also used for routine screening in people with a family history of diabetes, or other risk factors such as being overweight or having had gestational diabetes previously.
Some people request it simply for a periodic check on their blood sugar as part of general health monitoring.
Because this profile includes fasting glucose, you should fast, having nothing to eat or drink except water for at least 8 hours beforehand, and tell the phlebotomist whether your sample is fasting or non-fasting when you attend. HbA1c does not need fasting.
A raised glucose or HbA1c result suggests your blood sugar has been running higher than expected, though a single result doesn't confirm diabetes on its own and usually needs repeating or interpreting alongside your symptoms and risk factors.
A low glucose reading can also need following up, depending on the circumstances of the test. Book a doctor's appointment to go through the report properly, particularly if either marker comes back outside what's expected.
If you want these markers alongside a doctor's examination and a wider health assessment, compare the Full Body MOT health check.

Yes, fasting is needed for the glucose component. Have nothing to eat or drink except water for at least 8 hours beforehand and tell the phlebotomist your fasting status.
Glucose shows your blood sugar at the moment of the test, while HbA1c gives an average picture over the past two to three months, so together they show a snapshot and a trend.
Not on its own. A raised result usually needs repeating or further testing, and your doctor will interpret it alongside your symptoms and risk factors.
