On the subject in the title: Reporting a discrepancy without making an allegation Working notes rather than a conclusion.

Asking about reporting a discrepancy directly, because I have read four threads on it and each answered a slightly different question.

The version I want answered is the narrow one: given the method stated below, is the result within what anyone else has seen? I am not asking what it means yet.

Method, numbers and the two assumptions I am aware of making are below. If the assumptions are wrong that is more useful to me than agreement.

The cost of a submission is worth stating. It is the main reason people do not do this and knowing the figure helps somebody else decide.

Coming back to post #22, because the follow-up matters more than the original answer.

Photograph the vial and the label before opening. It costs ten seconds and it is what turns a report into something checkable.

I would treat the number as indicative rather than as a measurement.

a.pereira, post #3: Confirming post #2 from a second method, which matters more than confirming it from a second person. Do not adjust a reported figure. Post what the laboratory said and put your interpretation in a separate sentence. Go to post

Building on post #29 rather than restating it.

Dosing and purity: a vial that is 99% pure might contain 80% of its label claim if the other mass is water, counter-ion, and excipient. Purity and content are different. Both matter for different reasons.

That has been true for the cases I have seen and I have not seen many.

That has held every time I have looked, which is not the same as always.

None of the above is medical advice and I am not qualified to give any.

This follows post #55 rather than contradicting it.

Reports of ordinary results are more valuable than reports of remarkable ones, precisely because only the remarkable ones get posted elsewhere.

One more caveat and then I will stop qualifying: the sample selected itself.

I have no financial interest in anything named in this thread and I want to say so before I comment on reporting a discrepancy, because it is the sort of subject where it matters.
