Comprehensive blood test to detect early signs of diabetes and prediabetes, improving well-being.

Diabetes and metabolic screening tests measure how well your body processes glucose — your primary fuel source. Fasting glucose gives a snapshot of your blood sugar after an overnight fast, while HbA1c reveals your average blood sugar over the past 2–3 months by measuring the percentage of hemoglobin proteins coated with sugar. An insulin test can detect insulin resistance — where your cells stop responding efficiently to insulin — often years before blood sugar levels rise into the diabetic range. This early detection window is critical because prediabetes and insulin resistance are reversible with lifestyle changes, while advanced type 2 diabetes requires lifelong management.

Key Details

Biomarkers
2–4 metabolic markers
Fasting Required
Yes, 10–12 hours for fasting glucose
Sample Type
Blood draw
Turnaround
Same day to 24 hours
Common Use
Diabetes screening, insulin resistance detection

Who Is This For?

Adults over 35 as part of routine screening (diabetes affects 1 in 10 adults globally). Anyone with a family history of type 2 diabetes. People who are overweight or physically inactive. Those experiencing increased thirst, frequent urination, unexplained weight loss, or fatigue. Women with a history of gestational diabetes or polycystic ovary syndrome (PCOS).

What's Included

Fasting blood glucose
HbA1c (glycated hemoglobin)
Fasting insulin (if included in panel)
HOMA-IR insulin resistance index (if insulin included)

Preparation Required

Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.

Biomarkers Tested

2
HbA1c (Glycated Haemoglobin) %

Reflects your average blood sugar over the past 2–3 months by measuring the percentage of hemoglobin with attached glucose. HbA1c is the gold standard for diagnosing and monitoring diabetes, unaffected by daily fluctuations.

Glucose mg/dL

Blood sugar — the body's primary energy source. Fasting glucose screens for diabetes and prediabetes. Chronically elevated glucose damages blood vessels and organs. Levels fluctuate with meals, stress, and physical activity.
