The Claim
In adults with type 2 diabetes, a red blood cell lifespan shorter than 75 days is associated with higher average blood glucose levels compared to those with longer red blood cell lifespans, even when HbA1c levels are similar, indicating that HbA1c may not accurately reflect true glycemic control in individuals with accelerated red blood cell turnover.
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, your actual blood sugar might be higher than what your A1c test shows — meaning the A1c test could be misleading for some people.
See the scientific wording
Adults with type 2 diabetes and red blood cell lifespan below 75 days have significantly higher average blood glucose levels compared to those with longer RBC lifespans, despite similar HbA1c values, suggesting that HbA1c may inaccurately reflect glycemic control in individuals with accelerated red blood cell turnover.
What the research says
1 studyStudy: Red Blood Cell Lifespan < 74 Days Can Clinically Reduce Hb1Ac Levels in Type 2 Diabetes
People with type 2 diabetes who have shorter-lived red blood cells may have normal HbA1c levels but actually have higher blood sugar, meaning the HbA1c test can be misleading.
