1. What is the Fructosamine to HbA1c Conversion?

The fructosamine to HbA1c conversion provides an estimated HbA1c value based on fructosamine levels. Fructosamine measures average blood glucose levels over the past 2-3 weeks, while HbA1c reflects average levels over the past 2-3 months.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( Fructosamine \) — Serum fructosamine level in micromoles per liter (µmol/L)
• 0.017 — Conversion coefficient
• 1.61 — Constant offset

Explanation: This linear equation provides an estimated HbA1c percentage based on measured fructosamine levels.

3. Importance of HbA1c Measurement

Details: HbA1c is a crucial marker for long-term glucose control in diabetes management. It helps assess treatment effectiveness and predict diabetes-related complications.

4. Using the Calculator

Tips: Enter fructosamine level in µmol/L. The value must be valid (greater than 0). The calculator will provide the estimated HbA1c percentage.

5. Frequently Asked Questions (FAQ)

Q1: Why convert fructosamine to HbA1c?
A: This conversion helps when HbA1c measurement is unavailable or when recent glycemic control needs to be estimated from fructosamine levels.

Q2: How accurate is this conversion?
A: While useful for estimation, individual variations may affect accuracy. Direct HbA1c measurement is preferred for clinical decisions.

Q3: When is fructosamine testing preferred?
A: Fructosamine is useful in conditions where HbA1c may be unreliable, such as anemia, hemoglobin variants, or pregnancy.

Q4: What are normal fructosamine values?
A: Normal fructosamine levels typically range between 200-285 µmol/L in non-diabetic individuals.

Q5: How often should these tests be done?
A: Monitoring frequency depends on individual diabetes management plans, but typically every 3-6 months for stable patients.
