“…Both hyponatremia and hypokalemia, medical emergencies requiring immediate therapeutic intervention, are frequently observed in patients admitted to the emergency department (ED). More specifically, the prevalence of moderate and severe hyponatremia in ED can be as high as 18% and 0.3%, respectively [3], whereas that of hypokalemia can be as high as 11% [4]. The timely identification of these conditions is as vital as the identification of the underlying cause.…”

Abstract:We describe here the case of a 84-year-old woman under warfarin therapy for atrial fibrillation, who was admitted to the Emergency Department for severe gluteal hemorrhage. Blood samples were drawn after patient admission and transported within 20 min to the laboratory. Results of laboratory testing revealed a markedly increased value of international normalized ratio and extremely low values of serum sodium (60 mmol/L) and potassium (1.4 mmol/L). A second serum sample was collected approximately 2 h after the former, showing normal values of both sodium (145 mmol/L) and potassium (3.5 mmol/L). The analysis of the specimen collected upon patient admission revealed the presence of a small, transparent fibrin gel in the serum, which was partially aspirated by the sample probe of the instrument. This case underscores the importance that serum samples need to be allowed to clot completely prior to centrifugation and analysis, especially those collected from patients under anticoagulant treatment.
