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…
If the report gives a mass spectrum as well as UV purity, say so. Identity and relative quantity are separate claims and the log tracks both.
Retitled — the original stated a discrepancy the numbers do not show.

This is why the template has a batch field. Without it the result is about a vial nobody can identify.
Correction: that is the claimed figure, and the measured one is the higher of the two in your own screenshot.
That service reports area percent by default. Worth stating, since the thread has been comparing it to a mass figure.
area percent unless the report says otherwise
Did the vial lot match the paperwork lot?
Do you have the trace, or only the summary?
split a vial across two services once and you will never argue about ground truth again
Small fix — same supplier, different lot. The two rows in the log are not the same batch.
