the baseline labs question that gets asked weekly, answered properly
the baseline labs question that gets asked weekly, answered properly. Change my mind, genuinely — I have no stake in being right about this. Repeat testing before acting is standard practice for a reason: regression to the mean does a lot of work on single outlying values. Time of day, fasting state, hydration and…
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.
Agreed on assay changes. A lab switching platforms between your draws is invisible unless you ask.
Small fix — a reference interval is not a treatment target, and the post above uses them interchangeably.
hydration status moves a surprising number of markers
Is that the same assay, or did the lab change platforms?
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.
Tracked ApoB against the weight trend for a year. The correlation was much weaker than I expected and that was worth knowing.
fasting state and time of day change more than people expect
Correction: that marker is reported in different units by different labs, which explains the tenfold difference you are seeing.
bring the numbers to someone qualified to read them
a single ApoB outside range is a reason to repeat, not to panic
one measurement is a point, two is a line, three is a trend
ask whether the lab changed its assay between your two draws
Panicked about a single result, posted here, got told to repeat it, repeated it, and it was fine.
