[Meta] the Medutest rule is doing its job and people should stop complaining
the Medutest rule is doing its job and people should stop complaining. This affects how posts get sorted and removed, so it belongs in the open. Inter-lab variance on this assay runs roughly a point either way, driven mostly by gradient and integration. Two results inside that band agree; they do not disagree…
Agreed on quoting the claim alongside the result. Half the arguments here are two people comparing to different reference numbers.

a result with no batch number is about a vial nobody can identify
results without method are gossip with decimals
Yes. Two services on the same batch is the strongest thing an individual member can produce, and it is not expensive.
Kept every report as a PDF with the batch in the filename. Two years in, it is the most useful folder I own.
Right, and a point or two between services is ordinary. It is agreement, and every month somebody posts it as a scandal.
A series across separate lots estimates a process. Repeat tests on one lot estimate the measurement. Both are useful and they answer different questions.
Area percent or net peptide content?
Disagree that this is a discrepancy. 97.6% against a claimed 97.0% is inside ordinary inter-lab variance in either direction.
Disagree that this is a discrepancy.
Agreed — and two services on one batch is the strongest thing any of us can produce individually.
WXT came back 99.1% on a claimed 98.5%, which is agreement not a discrepancy
