my TSH moved and I cannot work out whether ferritin is why
my TSH moved and I cannot work out whether ferritin is why. I have gone back and forth on this for months. How to make a panel worth comparing, which is most of the value people leave on the table. Standardise the conditions: same lab, same fasting state, same rough time of day, same point in the week, similar…
assay method matters, especially between different labs
The confounding problem, stated plainly, because this board keeps stepping on it.
Substantial weight loss moves lipids, liver enzymes, insulin sensitivity markers and several others in its own right. If you are losing weight while taking something, any change in those markers has at least two candidate explanations and you cannot separate them from your own panel.
What you can do is standardise, take a baseline, keep the series long, and be honest in your posts about what is and is not attributable. The threads that say "this compound did X to my ApoB" almost never have the design to support the claim, mine included.

edit_for_clarity is right that a reference interval is not a target. It is a description of a population.
That is a non-fasting value and the interval you are comparing it against is a fasting one.
Disagree with reading anything into that. One value, one morning, and you changed two other things in the same window.
ApoB is the one worth adding if you only add one
Left up. It is a question about how to compare panels, not a request for interpretation.
bring the numbers to someone qualified to read them
Added ApoB to the panel after a thread here. It told me something the standard lipid panel had been hiding.
