across 48 hospitals in the Chicago metro. Lowest at MacNeal Hospital Gottlieb Community Health Services Corporation, highest at Ann & Robert H. Lurie Children's Hospital of Chicago. Both are figures those hospitals published themselves — nothing here is averaged, estimated or rounded.
Every figure above comes from the 48 hospitals listed below and from the single billing code hospitals use for it. Each is that hospital's own published figure. 3 other hospitals publish only a formula for this — a percentage of some other number rather than a price — so they are not in these figures at all.

48 hospitals publish a negotiated rate for Kidney function test in an outpatient setting, and the dearest of those figures is $80.22, though the cheapest sits far enough below the middle of what the others publish that this summary does not state it as the bottom of a range. 16 of those hospitals published a figure unlike what its peers published for the same thing. 18 hospitals publish a negotiated rate for Kidney function test in an inpatient setting, and their figures run from $2.44 to $525.62, with 7 of those hospitals publishing a figure unlike what its peers published for the same thing. 4 hospitals publish only a formula for Kidney function test — a percentage of some other number rather than a price — so they are in none of these figures.
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.
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.
