Is ApoB useful for blood sugar?

Apolipoprotein B (ApoB) is a key marker for the number of atherogenic lipoproteins and is primarily used for cardiovascular risk assessment. There is no established direct utility for measuring blood sugar or diagnosing diabetes. While there is an indirect link via metabolic syndrome, ApoB does not replace standard glycemic markers such as fasting glucose, HbA1c, or oral glucose tolerance test. The evidence from the provided context is unclear, as no specific studies on ApoB and blood sugar are mentioned. Caveat: ApoB testing is validated for cardiovascular risk stratification, not for direct blood sugar control. For comprehensive metabolic evaluation, both parameters should be assessed separately.
