Elevated serum and/or plasma potassium is an occasional occurrence in patients presenting
with severe leukocytosis. The term pseudohyperkalemia applies to these conditions in which …

Pseudohyperkalemia refers to an elevated in vitro potassium level, but without in vivo
hyperkalemia. 1 Of 991 patients with CLL and a leukocyte count of 50× 10 9/L or higher …

Pseudohyperkalemia, a false elevation of potassium level in vitro, can be observed in
chronic lymphocytic leukemia (CLL) patients due to fragility of leukocytes along with a high …

An artifactually elevated measured potassium level is referred to as pseudohyperkalemia or
false/apparent/spurious hyperkalemia, first described with extreme leukocytosis.[1] It has …

Pseudohyperkalemia is an uncommon finding in chronic lymphocytic leukemia. It is a
misleading condition that could lead to iatrogenic hypokalemia when unwarranted treatment …

Discussion Differentiation of hyperkalemia and pseudohyperkalemia is a critical skill for the
EP. We discuss multiple causes of hyperkalemia and pseudohyperkalemia in an effort to …

Pseudohyperkalemia is an uncommon finding in chronic lymphocytic leukemia. It is a
misleading condition that could lead to iatrogenic hypokalemia when unwarranted treatment …

The term pseudohyperkalemia refers to a false elevation in serum potassium levels due to
potassium release from cells in vitro. Falsely elevated potassium levels have been reported …

Discussion: Among those with CLL, pseudohyperkalemia is not rare. In a study investigating
119 hyperkalemic episodes in a cohort of patients with CLL, 41.2% of the episodes were …

Chronic lymphocytic leukemia (CLL) is characterized by excessive production of abnormal
lymphocytes in the bone marrow. It usually presents as hepatosplenomegaly and …
