HbA1c Test for Diabetes Monitoring
Feb 18, 2026
HbA1c Test for Diabetes Monitoring
An HbA1c test measures your average blood sugar levels over the past 2-3 months by detecting the percentage of haemoglobin with glucose attached—making it the gold standard for monitoring diabetes control, as keeping HbA1c in target range significantly reduces risk of diabetes complications including eye damage, kidney disease, and nerve damage.
At Blood Test London, HbA1c testing costs from £245 with results in 2-3 days.
