The Claim

In patients with type 2 diabetes and HbA1c <7%, those with red blood cell lifespan less than 90 days have a 33.87% prevalence of estimated HbA1c ≥7%, compared to 12.50% in those with red blood cell lifespan of 90 days or more, suggesting that shortened red blood cell survival may lead to underestimation of true glycemic control in a substantial proportion of patients.

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.

In plain English

Some people with diabetes might seem to have good blood sugar control based on standard tests, but if their red blood cells don’t live as long, the test could be misleading — and nearly 1 in 3 of these patients might actually have worse blood sugar levels than the test shows.

See the scientific wording

In type 2 diabetes patients with HbA1c <7%, those with red blood cell lifespan <90 days have a 33.87% prevalence of estimated HbA1c ≥7%, compared to 12.50% in those with RBC lifespan ≥90 days, indicating that nearly one-third of patients deemed to have good control may actually have suboptimal glycemia due to shortened RBC survival.

  1. Study: The influence of shorter red blood cell lifespan on the rate of HbA1c target achieved in type 2 diabetes patients with a HbA1c detection value lower than 7%

    The study found that in diabetics with seemingly good blood sugar control, those with shorter-lived red blood cells were much more likely to actually have poor control than their HbA1c suggests.
