Investigate concomitant and spurious high potassium and low sodium results in heparinized plasma.
Potassium and sodium values were measured from heparinized plasma and serum in a patient with B-cell non-Hodgkin lymphoma using both an automated chemistry analyzer (indirect ion selective electrode) and blood gas analyzer (direct ion selective electrode).
Potassium levels were significantly increased while sodium levels were significantly decreased in heparinized plasma compared to serum on several occasions.
To our knowledge, concomitant reverse pseudohyperkalemia and pseudohyponatremia has not been reported previously. We postulate the discrepancy between plasma and serum sodium (pseudohyponatremia in plasma) may be unique to cases of reverse pseudohyperkalemia with extreme potassium elevations.
研究肝素化血浆中同时出现的假性高钾血症和假性低钠血症。
使用自动化学分析仪（间接离子选择电极）和血气分析仪（直接离子选择电极），对一名B细胞非霍奇金淋巴瘤患者的肝素化血浆和血清中的钾和钠值进行测量。
在多个时间点，与血清相比，肝素化血浆中的钾水平显著升高，而钠水平显著降低。
据我们所知，此前尚未报道过同时出现的反向假性高钾血症和假性低钠血症。我们推测，血浆和血清钠之间的差异（血浆中的假性低钠血症）可能是极端钾升高导致的反向假性高钾血症病例所特有的。
