What is HbA1c and Why Does It Matter?
HbA1c stands for glycated haemoglobin. It is formed when haemoglobin, the protein in your red blood cells that carries oxygen, joins with glucose in your bloodstream. By measuring your HbA1c levels, we can see a reliable overall picture of your average blood sugar levels over the past two to three months, rather than just a single snapshot in time.
This makes HbA1c testing significantly more informative than a standard blood glucose test, which only reflects your sugar levels at that exact moment. A standard glucose test can easily miss early warning signs that the HbA1c test would reliably detect. Contact us today to book your screening.
HbA1c vs Standard Blood Glucose: What is the Difference?
A standard blood glucose test only tells you what your blood sugar is at that exact moment, and levels fluctuate constantly throughout the day. The HbA1c test is different. It measures your average blood sugar levels over the past eight to twelve weeks using a quick finger-prick sample, with no fasting required. This long-term view makes it a far more reliable tool for detecting early signs of prediabetes or diabetes that a single glucose reading could easily miss.

HbA1c Diagnostic Ranges
Your HbA1c result is used to classify your blood sugar status across three categories.
Normal
Below or up to 40 mmol/mol (6% or below). Blood sugar levels are within the healthy range.Prediabetic
Between 42 and 47 mmol/mol (6% to 6.4%). Blood sugar is raised.Diabetic
48 mmol/mol or above (6.5% or above). Consistent with a diabetes diagnosis.Important Note
Screening results are not a diagnosis. A confirmed diagnosis requires follow-up testing by your GP.Diabetes Screening: Your Questions Answered
Everything you need to know about HbA1c testing at Robertsons Pharmacy.
No. One of the key advantages of the HbA1c test is that it does not require fasting. It measures your average blood sugar levels over the past two to three months, so what you ate or drank before your appointment does not affect the result.
An HbA1c test is particularly recommended if you are over 45, have a family history of type 2 diabetes, are overweight, have high blood pressure, or have previously been told you have prediabetes. Anyone who wants to understand their blood sugar health can benefit from the screening.
A result in the prediabetic or diabetic range is not a formal diagnosis. Our team will explain your result clearly and advise on next steps. A confirmed diagnosis of diabetes requires follow-up testing by your GP. We will provide a written summary of your result and can advise on lifestyle changes that may help.
