Diagnostic reactions are those used in medicine to figure out what may be causing a problem. Can you go into detail concerning one such test you or someone you know has undergone? Share one balanced chemical equation related to this, and be sure to be specific (a urine test or blood test doesn't tell us what is being tested for in urine or blood, so be specific about what precisely is being looked at within any medium).
