ferritin — my 22-week log, condensed into one table
ferritin — my 22-week log, condensed into one table. It is the sort of thing everyone half-believes and nobody writes down.
My A1c moved and I spent a fortnight convinced I knew why. The repeat six weeks later was back in range and I had changed nothing.
Compared two draws across two labs and spent a week worrying before finding out the assays were different.
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.
Happy to answer the boring questions. Those are usually the ones worth asking.
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.
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.
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.

Agreed — and standardising the draw conditions is the cheapest improvement available.
Same view — ApoB if you add one thing. It answers a question the standard panel only gestures at.
weight loss itself moves several of these independently
lab reference ranges are not treatment targets
same lab, same conditions, or you are comparing noise
Cosigning on baseline. The panel I regret most is the one I did not take before starting.

micro_bump_mick is right that a reference interval is not a target. It is a description of a population.
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.
ask whether the lab changed its assay between your two draws
Nobody here can interpret your panel and this comment is not doing so. What a board can usefully do is help you ask better questions of somebody who can.
Careful — that is a question for whoever ordered the panel, and nobody in this thread can answer it responsibly.
a single eGFR outside range is a reason to repeat, not to panic
Agreed on assay changes. A lab switching platforms between your draws is invisible unless you ask.
Agreed. The trend is the signal. A single value is a snapshot of one morning.
Brought the whole set to my clinician rather than one flagged value. Completely different conversation.
