why does nobody talk about batch

PeptideMeter Clean Column ×9

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

I have been tracking purity against eGFR for 9 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.

Disagree. What you are describing is consistent with Janoshik, not with what you concluded.

Strongly agree. Below-spec results matter as much as good ones.

inter-lab variance is real, 5 points is inside normal

the 93.7% result confirmed the vendor claim, that is the signal

You have restated the marketing copy. What is the actual substance here.

reship and retest is the honest way to handle a low result

You have restated the marketing copy.

Yes, exactly this, and it is the bit that took me 34 weeks to accept.
