I want to find all patients who have had a K+ (Potassium) blood test result with a value greater than 1 mmol/l in the chemistry panel of the Blood Gases test, within any time frame, with a specificity scale of 0, accuracy scale of 100, and panel timing set to ANY. This query is focused on a single item (K+ blood test result) and is not a synonym for another item.
