Kidney function test

A blood test panel assessing how the kidneys are working.

15 hospitals · 33 published rates Cheapest $6.35 · dearest $10.65

Sorted cheapest first. A published figure that behaves like a placeholder rather than a real price — one cent, or a figure orders of magnitude below what other hospitals publish for the same billing code — never leads this order. It stays listed, after every other figure, ordered by its own amount among the others like it.

Nothing was excluded: none of the figures published here behave like a placeholder rather than a price.

Comparisons against other hospitals were computed on 2 November 2026. Each price carries its own fetch date; a comparison is a snapshot of what other hospitals had published when it ran, not a standing fact.

Why a range? One insurer publishes different rates for different plans at the same hospital — a PPO and an HMO under the same name can differ several times over. We show what the hospital published rather than collapsing it into a single number that might not be yours.
