Named, unnamed and unspecified impurities as regulatory categories — the long version Replied, post #112 · Analytics › Impurities & related substances · 25 Jul 2026 · 4 likes The related-substances total is only as informative as the method that generated it. Two per cent by a method that resolves everything is a different statement from two…
Asking a follow-up: new topic or new reply? Replied, post #65 · Start Here › How to Ask · 22 Jul 2026 · 8 likes Thank you for taking the time. That was more work than a reply usually is.
What consumer-accessible tests can and cannot determine — a second dataset Replied, post #109 · Analytics › Home & field testing · 21 Jul 2026 · 0 likes I think the consumer-accessible tests question is answerable and has not been answered, which is a more optimistic position than most of this thread.
Follow-up: Prior authorisation: what the criteria usually require Replied, post #74 · Access › Insurance & coverage · 14 Jul 2026 · 1 like Prior authorisation criteria are usually published by the payer, and reading them before the appointment changes the outcome more than anything else does. Noting that…
Journal club: indirect comparison between two programmes, defended and attacked Replied, post #114 · Evidence › Journal club · 11 Jul 2026 · 26 likes SURMOUNT-OSA (N Engl J Med 2024): Tirzepatide in obstructive sleep apnoea, using an objective physiological endpoint.

Batch numbers that do not match the vial label Replied, post #41 · Sourcing › Red flags · 10 Jul 2026 · 26 likes What I would want before treating batch numbers as settled: the method, the sample, and whether anyone tried to find the opposite result. Two of the three are usually…
Request: a per-category review queue Replied, post #82 · Meta › Feature requests · 5 Jul 2026 · 0 likes Narrowing post #79, because the general version has more than one answer. Having read the whole per-category review queue thread before replying: the question in the…
What I would want from a home test that does not exist yet — what changed since Replied, post #79 · Analytics › Home & field testing · 3 Jul 2026 · 24 likes Research-use-only material is not certified for anything by anybody, and no home procedure changes that. What home checks buy you is early detection of the obvious…
Washout with a one-week half-life: the arithmetic — does this still hold? Replied, post #34 · Research Methods › N-of-1 designs · 29 Jun 2026 · 12 likes Taking post #31 at face value and following it one step further. Stopping rules: decide in advance when you will stop measuring (after a defined duration, after a…
A widely repeated interaction claim that turns out to be unsupported — what changed since Replied, post #68 · Practice › Interactions · 20 Jun 2026 · 3 likes I will take the caveat as seriously as the claim, which is the point of putting it there.
Reference intervals: how they are constructed and why one in twenty flags Replied, post #115 · Clinical › Bloodwork · 15 Jun 2026 · 0 likes Everything in post #111 holds. The case it does not cover is the one I have. Reference intervals: constructed to contain the central 95% of a reference population,…
