HbA1c reflects your average blood sugar over roughly the previous two to three months. It does not show day-to-day changes or single high readings.
The result can be less reliable with anaemia, some inherited haemoglobin variants, recent blood loss or transfusion, pregnancy and kidney disease. In these situations a doctor may use a different test, such as a fasting glucose.
A raised or unexpected result should be discussed with a doctor, who may repeat it. For a wider metabolic panel with liver, kidney and thyroid markers, compare the Complete Metabolic blood test. For a doctor-led assessment with an examination, see a Health MOT at Health Screening Clinic.
