Pseudohyperkalaemia in thrombocythaemia, in its primary form or associated with polycythaemia vera, can occur with platelet counts in excess of 600 X 10(9)/l, and it is not related to high leukocyte or thrombocyte counts. An increment of 0.15 mmol/l serum potassium was found for every 100 X 10(9)/l rise in platelet count with a correlation coefficient of 0.82. Potassium from platelets is not released during the aggregation phase but during the degranulation phase of the coagulation process.
血小板增多症（原发性或与真性红细胞增多症相关）中的假性高钾血症，可在血小板计数超过600×10⁹/L时发生，且与高白细胞或血小板计数无关。血小板计数每升高100×10⁹/L，血清钾增加0.15 mmol/L，相关系数为0.82。血小板中的钾不是在聚集阶段而是在凝血过程的脱颗粒阶段释放。
