The Claim
In patients with transfusion-dependent thalassemia, HbA1c levels are significantly elevated, with a mean of 6.94% (±0.49%), and 85.7% of individuals have HbA1c values above 6.4%, indicating prediabetes or diabetes, despite 74.3% having normal fasting blood glucose levels, suggesting that HbA1c may not accurately reflect true glycemic control in this population.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with a blood disorder called thalassemia who need regular blood transfusions often show high blood sugar on HbA1c tests, but their actual blood sugar is normal—so the test might be giving false alarms in these patients.
See the scientific wording
In transfusion-dependent thalassemia (TDT) patients, HbA1c levels are significantly elevated—mean 6.94% (±0.49%)—with 85.7% of individuals falling into the diabetic range (>6.4%), despite normal fasting blood glucose levels in 74.3% of cases, indicating that HbA1c may not accurately reflect glycemic status in this population.
What the research says
1 studyThe study found that thalassemia patients often have high HbA1c levels even when their blood sugar is normal, so HbA1c can be misleading for diagnosing diabetes in these patients.
