The Claim
In adults with type 2 diabetes, a red blood cell lifespan shorter than 75 days is associated with a 14.07% contribution to the variation in HbA1c levels, which is significantly higher compared to individuals with longer red blood cell lifespans, suggesting that shortened red blood cell survival may lead to underestimation of long-term glycemic control when HbA1c is used as the sole measure.
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 you have type 2 diabetes and your red blood cells don’t live as long—less than 75 days—your A1c test might not give a true picture of your blood sugar control, because the test could show lower numbers than reality.
See the scientific wording
In adults with type 2 diabetes, a red blood cell lifespan shorter than 75 days is associated with a 14.07% contribution to variation in HbA1c levels, significantly higher than in those with longer RBC lifespans, indicating that shortened RBC survival may lead to underestimation of long-term blood glucose control when relying solely on HbA1c measurements.
What the research says
1 studyStudy: Red Blood Cell Lifespan < 74 Days Can Clinically Reduce Hb1Ac Levels in Type 2 Diabetes
The study found that in people with type 2 diabetes and short-lived red blood cells, the HbA1c test doesn’t fully reflect their actual blood sugar levels, which can lead to misleading results.
