What is it?
A measurement of your blood sugar after at least 8 hours without food, reflecting baseline glucose regulation.
Why it matters for long-term health
A simple, fast and cheap window into early insulin resistance. Together with HbA1c and insulin it forms the metabolic triad.
Longevity and healthy ageing
Even high-normal fasting glucose accelerates vascular ageing, increases dementia risk, and predicts later diabetes by 5–10 years.
What a high result may indicate
5.6–6.9 mmol/L = impaired fasting glucose / prediabetes. ≥7.0 mmol/L on two occasions = diabetes.
What a low result may indicate
under 3.9 mmol/L = hypoglycaemia — investigate for medication effect, alcohol, adrenal insufficiency or rarely insulinoma.

How a British GP interprets your result
A single high reading does not diagnose diabetes — we confirm with HbA1c and fasting insulin and rule out stress hyperglycaemia.
Further investigations we may arrange
- •HbA1c
- •Fasting insulin & HOMA-IR
- •Oral glucose tolerance test
- •Lipid panel
- •Liver function
Lifestyle measures that may improve your result
- •Reduce ultra-processed carbohydrates
- •Walk after meals
- •Resistance training
- •Sleep optimisation
- •Weight loss if BMI > 25
Evidence-based treatment options
- •Lifestyle first-line
- •Metformin where appropriate
- •GLP-1 agonists for prediabetes with obesity
When to retest
3–6 months if abnormal, annually for screening.

Frequently asked questions
Can I have a Fasting Glucose blood test at home in Dubai?+
Yes — our DHA-licensed nurse draws Fasting Glucose at your home, hotel, villa or office anywhere in Dubai, usually within 60–90 minutes of booking. Your result is then reviewed by a British-trained GP who calls you to explain it in plain English.
Do I need to fast before a Fasting Glucose test?+
Most patients do not need to fast for Fasting Glucose specifically. If we are running a fuller panel (lipids, glucose, insulin) we will advise an overnight fast — our team confirms this when you book.
How quickly will I get my Fasting Glucose result?+
Standard turnaround is 24–48 hours from a DHA-accredited laboratory. Your named British GP then calls you personally with the interpretation and a written wellness plan — not a PDF you have to decode alone.
Is Fasting Glucose covered by insurance?+
Most premium UAE and international insurers reimburse — we provide a fully coded invoice at the visit. Reimbursement typically arrives within 5–10 working days.
