The Claim
Hemoglobinopathies can cause falsely low HbA1c measurements in individuals with diabetes, leading to an underestimation of long-term glycemic control and potentially resulting in inadequate treatment when HbA1c is used without supporting plasma glucose or self-monitoring blood glucose data.
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 has certain blood conditions like sickle cell trait, their A1c test might show lower blood sugar levels than they actually have, which could trick doctors into thinking diabetes is under control when it's not — especially if they don't also check regular blood sugar tests.
See the scientific wording
Hemoglobinopathies can lead to falsely low HbA1c values in patients with diabetes, potentially resulting in underestimation of glycemic control and risk of inadequate treatment if HbA1c is used without corroborating plasma glucose or self-monitoring data.
What the research says
1 studyStudy: Plasma glucose and HbA1c discrepancy may indicate hemoglobinopathy: a case series
The study found that some people with diabetes and blood disorders have deceptively low HbA1c readings, so doctors might think their blood sugar is under control when it’s not. This supports the idea that other tests like blood sugar checks are needed in these cases.
