comment on what would you tell week-1 you about ferritin in c/bloodwork · 6 points · 2 years ago
Repeat testing before acting is standard practice for a reason: regression to the mean does a lot of work on single outlying values.

A beyond-use date derived from published stability data means something different from one assigned by default rule. Asking which is a fair question and the answer is usually available.

Right, and the concentration genuinely can differ from the branded product, which breaks people’s arithmetic.
comment on the baseline labs question that gets asked weekly, answered properly in c/bloodwork · 142 points · 2 years ago
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.

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.

503A or 503B — do you know which?
