On-the-spot blood HbA1c testing in points of care.

Why HbA1c testing matters in pharmacy?

Measuring HbA1c provides insight into long-term blood glucose control and helps identify individuals at risk, including those with prediabetes, diabetes, metabolic syndrome, or other conditions influenced by elevated glucose levels. This allows pharmacies and other health-focused businesses to offer immediate, value-added testing and practical guidance directly at the point of care.

Offering HbA1c testing allows pharmacies to:

• Expand their range of in-store health services.

How is HbA1c measured?

• Sample: Small blood sample.
• Units: Results are primarily reported as a percentage (%). Some reports also include IFCC units (mmol/mol), and estimated average glucose (eAG) reference tables may be used for interpretation.

HbA1c can be measured using capillary whole blood from a fingerstick at the point of care or from venous whole blood. Fasting is not required.

Additional consideration: Because capillary point-of-care results may vary, diagnostic decisions should be confirmed with a venous blood sample where appropriate.

HbA1c testing with Igloo Reader Pro

In pharmacy and primary care business settings, HbA1c can be measured from a small capillary blood sample using the Igloo Reader Pro, in line with the instructions for use. Results can be stored in the Igloo.health app and monitored over time, and interpreted alongside other relevant biomarkers to support follow-up and referral decisions.

Benefits for pharmacies and primary care practices:

• Offer rapid HbA1c testing during routine visits.
• Broaden available services without adding operational complexity.
• Support early detection of glycemia.
• Integrate smoothly into existing workflows and daily practice routines.

What are normal HbA1c values?

HbA1c values below 5.7% (approximately <39 mmol/mol) are generally consistent with normal long-term blood glucose control.

What are high HbA1c levels?

Elevated risk (prediabetes):

HbA1c values between 5.7% and 6.4% (approximately 39–47 mmol/mol) indicate impaired glucose regulation and an increased risk of developing diabetes.

Diabetes range:

HbA1c values of 6.5% or higher (≥48 mmol/mol) are consistent with diabetes when measured using a standardized method. Diagnosis should be confirmed with a healthcare professional, for example by repeat testing or complementary glucose-based assessments, and always interpreted alongside the clinical context.

What factors influence HbA1c?

Red blood cell lifespan and hemoglobin levels may effect the HbA1c level. Iron-deficiency anemia can elevate HbA1c that might lead to incorrect interpretations. Hemolysis or acute blood loss can lower HbA1c level. Hemoglobin level variations, chronic kidney disease, pregnancy, and recent transfusions of various kinds may distort HbA1c blood test results. 

Why pharmacies should offer HbA1c testing?

Adding HbA1c testing allows pharmacies to:

• Strengthen their role in supporting metabolic and diabetes-related health.
• Offer rapid blood glucose control assessments directly to customers.
• Provide tailored guidance, lifestyle advice, supplements, or referrals based on results.
• Create additional revenue opportunities through diagnostic testing services.
