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...

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.

There's a new math formula that fixes HbA1c blood sugar readings for people with type 2 diabetes when their red blood cells don't live as long as usual — this could give a more accurate picture of their blood sugar control.

If your red blood cells live longer or shorter than average, your A1C test might not give a true picture of your average blood sugar levels.

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.

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.
