The Claim
In patients with diabetes, discrepancies between plasma glucose levels and HbA1c can indicate underlying hemoglobinopathies, even in the absence of significant hematologic abnormalities or when only isolated microcytosis is present, suggesting that HbA1c may be falsely low in such cases and that hemoglobin electrophoresis should be considered to ensure accurate diagnosis and appropriate treatment planning.
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.
If someone with diabetes has blood sugar numbers that don't match their A1c test, it might be due to a hidden blood condition — even if their blood tests look mostly normal. In those cases, a special blood test could help get the right diagnosis.
See the scientific wording
In patients with diabetes, discrepancies between plasma glucose levels and HbA1c may indicate the presence of hemoglobinopathies, even when hematologic parameters are normal or show only isolated microcytosis, suggesting that HbA1c can be falsely low in such cases and that hemoglobin electrophoresis should be considered for accurate diagnosis and treatment planning.
What the research says
1 studyStudy: Plasma glucose and HbA1c discrepancy may indicate hemoglobinopathy: a case series
The study found that when blood sugar and HbA1c don’t match in diabetic patients, it can be a sign of a hidden blood disorder, even if blood tests look normal. This supports the idea that doctors should check for these disorders using a special test.
