The Claim

In adults with type 2 diabetes and a red blood cell lifespan of 66 days or less, the mathematical correction formula HbA1c(c) = -0.05629 × RBC lifespan + 1.127 × HbA1c + 3.178 can be applied to estimate a more accurate measure of glycemic control, with a reported correlation coefficient of R = 0.7360 between the corrected HbA1c value and estimated average glucose levels.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

If you have type 2 diabetes and your red blood cells don’t live very long, there’s a math formula that can give a better picture of your blood sugar control by adjusting your HbA1c test result.

See the scientific wording

In adults with type 2 diabetes and red blood cell lifespan ≤ 66 days, a mathematical correction formula HbA1c(c) = -0.05629×RBC lifespan + 1.127×HbA1c + 3.178 can be used to estimate a more accurate glycemic control value, with a correlation coefficient of R = 0.7360 between corrected HbA1c and estimated average glucose.

What the research says

1 study
  1. Study: Rectify the impact of shorter red blood cell lifespan upon HbA1c detection values in T2DM patients: modeling and internal-external verification

    The study tested the exact formula mentioned in the claim and found it works well to give a more accurate picture of blood sugar levels in people with type 2 diabetes who have shorter-lived red blood cells.
