baseline labs are the most under-discussed thing on this board
baseline labs are the most under-discussed thing on this board. Making the case below, and I expect to lose some of it in the comments.
Time of day, fasting state, hydration and recent exercise all move common markers. Standardising the draw conditions is free and it removes most of the apparent variability.
ApoB counts atherogenic particles rather than the cholesterol they carry, which is why it can diverge from LDL-C and why it is the addition most worth making.
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.
Would rather be corrected in public than confident in private.
best — the order this archive was captured in
Substantial weight loss independently moves lipids, liver enzymes and several other markers. Attributing a change to a compound while losing weight is confounded by design.
Panicked about a single result, posted here, got told to repeat it, repeated it, and it was fine.
That is a non-fasting value and the interval you are comparing it against is a fasting one.
Careful — that is a question for whoever ordered the panel, and nobody in this thread can answer it responsibly.
Different laboratories use different assay platforms with different calibration. Comparing across labs adds a systematic offset that is invisible on the report.
