Trust level 3 requirements: a clarification — does this still hold? Replied, post #86 · Meta › Announcements · 20 Jul 2026 · 19 likes Clarification on the announcement, because two people have now read it the same wrong way. That is a writing failure rather than a reading one, and the original has…
Request: a per-category review queue Replied, post #115 · Meta › Feature requests · 19 Jul 2026 · 7 likes Both of these are in the same family and staff would rather do one thing well than two things partly. If the range link exists, the citation relationship gets much…
Restarting after a long gap: what the labelling implies Replied, post #29 · Practice › Dosing & titration · 16 Jul 2026 · 23 likes A missed dose in a weekly schedule is not a trough to chase. With a week-long half-life you are perturbing a slowly moving average, and the labelling for licensed…

Revisiting: Can a home kit substitute for a laboratory report? A careful no Replied, post #45 · Analytics › Home & field testing · 4 Jul 2026 · 25 likes Reagent shelf life is a real constraint on kits and is frequently ignored.

How to ask a question when you cannot say why you are asking it Replied, post #24 · Start Here › How to Ask · 27 Jun 2026 · 1 like Say what you have already ruled out. "It is not the diluent because I tried a second vial from a different box" saves three replies suggesting the diluent.

Recording a dissent on a document rather than suppressing it Replied, post #20 · Documentation › Doc review · 17 Jun 2026 · 11 likes Point three stops most nominations. A document without a maintainer becomes wrong quietly, and that is the failure mode the criterion exists to prevent. That is the…

Follow-up: A parcel that arrived warm: a decision process, not a verdict Replied, post #23 · Practice › Storage & stability · 11 May 2026 · 13 likes Post #22 is right about the mechanism and I think understates the practical bit.

Validating a method you did not develop Replied, post #14 · Analytics › Method validation · 15 Apr 2026 · 23 likes An independent laboratory's method being different from the supplier's is not a discrepancy. It becomes one only when the results differ by more than both methods'…
