Hypokalemia Diagnostic Algorithm To assess potassium excretion: perform 24-hour urine collection or alternatively obtain potassium-to-creatinine ratio on a spot urine sample. Check The TTKG: During hypokalemia (K⁺ <3.5 mEq/L), the TTKG should be <3; greater values suggest renal K wasting. #Hypokalemia #Diagnosis #Algorithm #TTKG #nephrology #low #potassium
