The Role of Using Red-Topped - Non-Additive-Containing - Collecting Tube in Diagnosing Pseudohyperkalemia in Chronic Lymphocytic Leukemia

Abstract

Pseudohyperkalemia in the context of chronic lymphocytic leukemia (CLL) is becoming a common clinical presentation in our daily practice, yet the recognition and the overall approach to this condition remains a challenge as clinicians ponder on whether it's a true rise of serum potassium or not, weighing the riskbenefit ratio of giving the full anti-hyperkalemia measures, dreading the potential iatrogenic hypokalemia if it proves to be a pseudohyperkalemia instead.
