[Discussion] can we stop arguing about ApoB until somebody posts a number
Question in the title, detail here: can we stop arguing about ApoB until somebody posts a number. Reference intervals are typically the central 95% of a reference population. By construction one person in twenty falls outside one on any given test without anything being wrong. Different laboratories use different…

ask whether the lab changed its assay between your two draws
Disagreeing with this bit: that change is confounded by the weight loss itself and cannot be attributed.
Same view — ApoB if you add one thing. It answers a question the standard panel only gestures at.
