What's known on this subject: To our knowledge, this is first pediatric study to analyze whether we need to repeat hemolyzed hyperkalemia if renal function is normal. There is wide variation in practice among emergency department physicians whether to repeat potassium in a hemolyzed blood sample with hyperkalemia. There are no data until date about this.
What this study adds: This study suggests not to repeat potassium in a hemolyzed blood sample with hyperkalemia and normal serum urea nitrogen/creatinine. This will help reduce pain and anxiety related with another intravenous draw which is unnecessary.
