Pseudohyperkalaemia is defined as a rise in serum potassium with concomitantly normal plasma potassium. The case of long undiagnosed pseudohyperkalaemia in an 84-year-old lady with thrombocytosis post splenectomy is presented. Presenting a historical perspective and the multifactorial aetiology of pseudohyperkalaemia the author underlines the importance of detecting apparent hyperkalaemia by testing the plasma potassium. Awareness of the possible causes of pseudohyperkalaemia increases the likelihood of it being detected earlier thereby decreasing the risk of harming the patient. Unnecessary treatment and investigation of pseudohyperkalaemia can cause harm to the patient in the form of undesired side effects, unnecessary investigations and concerns, and potentially dangerous iatrogenically induced cardiac arrhythmias.
假性高钾血症定义为血清钾升高，同时血浆钾正常。本文报告了一例 84 岁女性在脾切除术后血小板增多症中出现长期未诊断的假性高钾血症。作者通过检测血浆钾来强调检测明显高钾血症的重要性，提出了假性高钾血症的历史观点和多种病因，假性高钾血症的潜在原因增加了更早发现的可能性，从而降低了对患者造成伤害的风险。假性高钾血症的不必要治疗和检查可能会对患者造成伤害，表现为不必要的副作用、不必要的检查和担忧，以及潜在危险的医源性诱导性心律失常。
