For Japanese adults with type 1 diabetes on a smart insulin pump, a new personalized blood sugar tracking method is way more accurate at guessing their lab HbA1c than the usual methods.

A new blood sugar tracking method works better than two older ones for Japanese adults with type 1 diabetes — it matches lab results much more closely.

For Japanese adults with type 1 diabetes, a new blood sugar tracking method called cHbA1c is way more accurate than the usual ones — it's really close to the lab test results most of the time.

For Japanese adults with type 1 diabetes, tracking blood sugar data between just two lab tests is usually enough to predict average blood sugar levels well, but you need data from five test intervals to accurately figure out how long their red blood cells live and how their bodies use glucose.

Sometimes, blood sugar tests that don’t use HbA1c might give a better picture of how well someone’s diabetes is managed—especially if things like blood disorders or other health issues make the standard HbA1c test less reliable.
