What our notes say

• The Absolute Non-Indication: Elevated serum urea or creatinine *alone* is never an absolute indication for emergency dialysis without a clinical or physiological complication (AEIOU). (Indications for dialysis)
• Her serum urea nitrogen is 15 mg/dL with creatinine of 1.1 mg/dL. (Immunopathology complete mcqs — Past Paper Questions & Answers)
• His serum urea nitrogen is 17 mg/dL with creatinine 1.0 mg/dL. (Immunopathology complete mcqs — Past Paper Questions & Answers)
• Laboratory studies show her serum urea nitrogen is 52 mg/dL with creatinine 5.3 mg/dL. (hematopathology — Past Paper Questions & Answers)
• | Serum urea & creatinine | Detects renal dysfunction causing toxicity or acidosis | Hyperkalaemia induces sine waves, blocks, arrest | (Arrhythmias and ECG interpretation)
• | Serum urea & creatinine | Renal etiology | Uremia indicates uremic pericarditis requiring urgent renal replacement therapy | (Pericarditis, effusion and tamponade)
