Pseudohyperkalaemia in essential thrombocytosis: an important clinical reminder.

Endocrinol Diabetes Metab Case Rep 2021 Apr 1;2021. Epub 2021 Apr 1.

Mater Dei Hospital of Malta, Department of Medicine, Msida, Malta.

Summary: An 82-year-old female was admitted to a general hospital due to progressive bilateral lower limb weakness. A T8-T9 extramedullary meningioma was diagnosed by MRI, and the patient was referred for excision of the tumour. During the patient's admission, she was noted to have persistent hyperkalaemia which was refractory to treatment. Read More

Pseudohyperkalaemia associated with leukaemic cell lysis during pneumatic tube transport of blood samples.

Pediatr Nephrol 2012 Jun 26;27(6):1029-31. Epub 2012 Feb 26.

Department of Haematology, Royal Manchester Children's Hospital, Manchester, UK.

Background: Pseudohyperkalaemia is relatively uncommon in children, but needs to be considered in cases where extreme hyperkalaemia is associated with normal renal function.

Case: A previously well 12 year-old boy presented with new onset T cell acute lymphoblastic leukaemia associated with a high peripheral blood white cell count. Plasma biochemistry tests on a blood sample sent to the laboratory using a pneumatic tube system showed a high plasma potassium level of 16. Read More

Pseudohyperkalaemia in Kawasaki disease.

Eur J Pediatr 1992 Jul;151(7):497-8

Department of Paediatrics, Juntendo University School of Medicine, Tokyo, Japan.

Pseudohyperkalaemia was observed in 3 of 16 patients with Kawasaki disease showing remarkably increased platelet counts. Their plasma potassium concentration, which is not affected by in vitro coagulation, was in the normal range despite the increased serum level. A significant correlation was observed between the platelet count and the increase in the serum potassium level resulting from blood coagulation, which was estimated by subtracting the plasma potassium level from the serum level.
