Follow-up: Prior authorisation: what the criteria usually require Replied, post #97 · Access › Insurance & coverage · 26 Jul 2026 · 16 likes Post #96 is right about the mechanism and I think understates the practical bit.

Submitting a sample: the process end to end Replied, post #64 · Sourcing › Independent verification · 7 Jul 2026 · 4 likes What I would check first on submitting a sample is whether the thing being measured moved or whether the way of measuring it moved. Those look identical in a graph.

Tracking a shortage from primary sources rather than rumour — the long version Replied, post #2 · Access › Shortages · 5 Jul 2026 · 5 likes Where I part company with the opening post, and it is a narrow parting.
