Twenty-five patients who were suspected clinically of having either polycythaemia rubra vera or secondary polycythaemia had no haematological abnormalities apart from a reduction in the plasma volume. Twenty-one were hypertensive. The plasma volume was lowest in those who were receiving treatment with diuretic agents, antihypertensive drugs, or steroid therapy. These cases demonstrate the need for blood volume studies in patients with high values for the blood haemoglobin and the packed cell volume in order to establish a differential diagnosis from myeloproliferative disorder or secondary polycythaemia.
25例临床上疑似患有真性红细胞增多症或继发性红细胞增多症的患者，除血浆容量减少外无血液学异常。21例患者患有高血压。接受利尿剂、抗高血压药物或类固醇治疗的患者血浆容量最低。这些病例表明，对于血红蛋白和血细胞比容值较高的患者，需要进行血容量研究，以便与骨髓增殖性疾病或继发性红细胞增多症进行鉴别诊断。
