Final answer:
Pseudo-hyperkalemia is a condition where leakage of potassium from red blood cells into the serum during blood sample collection can artificially elevate measured potassium levels, resulting in apparent hyperkalemia.
Step-by-step explanation:
Pseudo-hyperkalemia is a condition that can lead to apparent hyperkalemia on laboratory measurements. It occurs when there is a leakage of potassium from red blood cells into the serum during blood sample collection. This leakage can artificially elevate the measured potassium levels in the blood, giving the appearance of hyperkalemia.
