Pseudohyperkalemia Caused by Thrombocytosis:a Case Report and Related Reporting Process Improvement
Severe hyperkalemia is an urgent medical condition that requires immediate clinical intervention. Pseudohyperkalemia interferes with the diagnosis of hyperkalemia.To prevent mis-diagnosis and mis-treatment,it is imperative for the clinical laboratory to accurately identify cases of pseudohyperkalemia before reporting results.We report a case where a patient was identified to have elevated serum potassium during hypertension follow-up period.Subsequently,this patient visited the Emergency Department and Outpatient Department multiple times and underwent a treatment process with high potassium,potassium lowering,low potassium,and potassium supplementation.Ultimately,the patient was diagnosed with pseudohyperkalemia caused by thrombocytosis.Based on this case report,we aim to optimize the laboratory information system to automatically identify pseudohyperkalemia caused by thrombocytosis and to improve the reporting process to avoid the risk of mis-diagnosis and unnecessary treatment for the future clinical practice.
