stalled for 13 weeks at 2.4mg and I refuse to panic this time. I have gone back and forth on this for months.
13 weeks and 2.4mg. Those are measured, not estimated, and not rounded up in my favour.
Brought the whole set to my clinician rather than one flagged value. Completely different conversation.
Tracked eGFR against the weight trend for a year. The correlation was much weaker than I expected and that was worth knowing.
Happy to answer the boring questions. Those are usually the ones worth asking.

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.
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.
Compared two draws across two labs and spent a week worrying before finding out the assays were different.
Correction: that marker is reported in different units by different labs, which explains the tenfold difference you are seeing.
Different laboratories use different assay platforms with different calibration. Comparing across labs adds a systematic offset that is invisible on the report.

hedda_adeyemi is right that a reference interval is not a target. It is a description of a population.
Repeat testing before acting is standard practice for a reason: regression to the mean does a lot of work on single outlying values.
a single TSH outside range is a reason to repeat, not to panic
