-
A1c
-
Glucose tolerance test (measure glucose before and after drinking a sugary beverage)

-
MRI-PDFF (magnetic resonance imaging-proton density fat fraction). An MRI scan, analyzed by AI (artificial intelligence) to measure the amount of fat in the liver.
-
Liver biopsy: This is an invasive procedure, that is only used in special cases. A small piece of liver tissue is removed and examined microscopically. It can determine if you have NAFLD/MASLD or a rare liver diseases that can mimic NAFLD/MASLD.
