  schema:description "Many hospitals still ask for a kidney blood test within three months before a CT scan with contrast dye, and cancel scans when it is missing. Since 2024 NICE has said a test from the past six months will do, and that when there is none, three questions about kidney disease and acute illness can decide whether a test is needed. How safely and how widely this works is not measured."@en ;
