ICD-11 3A10.3 — Familial pseudohyperkalaemia

A disease caused by a genetically inherited mutation. This disease is characterised by a temperature-dependent defect in red cell membrane permeability to potassium that leads to high in vitro potassium levels in samples stored below 37°C leading to elevated potassium levels in the blood that does not reflect the true potassium level. Confirmation is by identification of genetic mutation through genetic testing.
