Revisiting: Liver enzymes drifting down and what that usually means posts 61–62

Clinical › Bloodwork thyroid function eGFR & renal function liver enzymes lipase & amylase

This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

post #60 is right about the mechanism and I think understates the practical bit.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.

Worth separating two things that post #58 runs together.

Reference intervals: constructed to contain the central 95% of a reference population, which means one in twenty healthy people falls outside one by definition. Add biological variation and analytical imprecision and the base rate of a meaningless flag is substantial.
