HbA1c is a blood test reflecting glucose exposure over approximately the previous two to three months. It is different from the fasting glucose measured today.
Is the target the same for everyone?
Age, pregnancy, duration of diabetes, heart or kidney disease, repeated low glucose, other medicines and daily circumstances affect the safest target. Do not increase or reduce treatment simply to match a number found online.
Why HbA1c and home readings can disagree
Recent blood loss or transfusion, iron-deficiency anaemia, haemoglobin disorders, kidney failure and conditions affecting red-cell lifespan can change the result. A home meter only records the times checked. Clinicians therefore compare HbA1c with fasting or post-meal values, symptoms and the laboratory context.
How often should it be checked?
Frequency depends on whether diabetes is newly diagnosed or stable, whether treatment changed recently, pregnancy, hypoglycaemia and whether the individual target is being met. Testing at intervals of a few months is useful for many people, but one fixed schedule is unsuitable for everyone. HbA1c does not replace kidney, eye, foot, BP and lipid review.
What the average hides
Two people with the same HbA1c may have different glucose patterns. One may be stable; another may alternate between high and low readings. Reviewing symptoms, meals, home monitoring and sometimes CGM can make decisions safer.
A raised report is a reason to understand the cause. Illness, stress, sleep, steroids, access to meals and difficulty taking medicines can all contribute.
What to do after the report
Bring current medicines and doses, dated glucose readings, meal timing and symptoms. Arrange earlier review for recurrent sweating, trembling, confusion or very low readings. Avoid doubling or stopping medicines yourself.
