FACT FIRST · ANALOGY SECOND
eGFR
Factual definition
Estimated glomerular filtration rate: a calculation using blood markers and other variables to estimate kidney filtering function. A single value does not on its own establish chronic kidney disease.
SATIRICAL ANALOGY — NOT A DEFINITION
An estimate, helpfully labeled as one, which people still try to turn into a final verdict.
