what would you tell week-1 you about ferritin

Baseline

what would you tell week-1 you about ferritin — that is what I am asking, and I have already read the wiki twice.

Draw at the same point in the week now, fasting, same lab. The noise dropped enormously once I standardised.

Brought the whole set to my clinician rather than one flagged value. Completely different conversation.

Tracked fasting insulin against the weight trend for a year. The correlation was much weaker than I expected and that was worth knowing.

Not medical advice, obviously, and nothing here is approved for human use. One person with a spreadsheet.

Repeat testing before acting is standard practice for a reason: regression to the mean does a lot of work on single outlying values.

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.

I would not draw a line through two points, especially when the second was taken at a different time of day.

ApoB is the one worth adding if you only add one

About c/bloodwork
