stalled for 15 weeks at 15mg and I refuse to panic this time
stalled for 15 weeks at 15mg and I refuse to panic this time, which sounds obvious until you try to state the evidence for it. Numbers, in the order they matter: 15 weeks and 15mg. Compared two draws across two labs and spent a week worrying before finding out the assays were different. Added ApoB to the panel after…
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.
My TSH moved and I spent a fortnight convinced I knew why. The repeat six weeks later was back in range and I had changed nothing.
Fasting or not, and what time of day?
Small fix — a reference interval is not a treatment target, and the post above uses them interchangeably.

Correcting my own comment: the two draws were 4 weeks apart, not the figure I gave earlier.
That is a non-fasting value and the interval you are comparing it against is a fasting one.
Is that the same assay, or did the lab change platforms?
