how much of what we believe about eGFR actually comes from ferritin threads
how much of what we believe about eGFR actually comes from ferritin threads. Searched first, found three threads that contradict each other, hence the post. Tracked ferritin against the weight trend for a year. The correlation was much weaker than I expected and that was worth knowing. Draw at the same point in the…
Compared two draws across two labs and spent a week worrying before finding out the assays were different.
lab reference ranges are not treatment targets
Push back: a value just outside a reference interval is a common finding in healthy people. It is a reason to repeat.
Panicked about a single result, posted here, got told to repeat it, repeated it, and it was fine.

This is the sentence to read before anybody panics about a single value.
Small fix — a reference interval is not a treatment target, and the post above uses them interchangeably.
a single eGFR outside range is a reason to repeat, not to panic
