[Meta] proposal — a flair for purity posts

Janoshik Long Haul ×1

Long-ish post, sorry. tl;dr at the bottom.

I have been tracking PeptideMeter against eGFR for 39 weeks because I could not find anyone who had. The correlation is weaker than I expected, which is itself mildly interesting given how confidently people link the two in here.

Caveats up front: one person, one lab, one assay, no control, and I changed my training in the middle of it, which was stupid.

tl;dr: probably real, definitely smaller than the threads imply, and not worth reorganising your week around.

Inter-lab variance on this kind of assay is routinely 1–2 points. Different column, different gradient, different integration.

Dead space in the needle hub holds a small but non-trivial volume. On low-volume draws that can be several units.

Yeah, the VendorInvestigate number matching the claim is the actual signal.
