目的：探讨血清甲状旁腺激素Ｍ（ＰＴＨＭ）含量测定对诊断慢性肾功能衰竭（ＣＲＦ）导致的继发性甲状旁腺功能亢进（ＳＨＰ）的临床价值和意义。方法：利用双抗放射免疫测定法对２７１例ＣＲＦ患者作血ＰＴＨＭ含量测定。结果：约８６％的患者血ＰＴＨＭ含量＞２７ｎｇ／ｄｌ的正常参考水平，其中约２５％的患者血ＰＴＨＭ含量＞２００ｎｇ／ｄｌ。血ＰＴＨＭ含量和患者的年龄或性别不存在相关性，但血ＰＴＨＭ含量和患者经历血液透析年限呈正相关（ｒ＝０６００）。结论：血ＰＴＨＭ测定对诊断ＳＨＰ有重要的临床价值，并对ＳＨＰ的监测有一定的参考价值。
Objective: To investigate the clinical value and significance of serum parathyroid hormone M (PTHM) in the diagnosis of secondary hyperparathyroidism (SHP) caused by chronic renal failure (CRF). Methods: 271 CRF patients were tested for PTHM by double-antibody radioimmunoassay. RESULTS: Approximately 86% of patients had normal reference levels of PTH-M> 27 ng / dl, with approximately 25% of patients having PTH-M levels> 200 ng / dl. Blood PTH M content and age or gender of the patient does not exist, but the blood PTH M content and patient experience hemodialysis was positively correlated (r = 0 600). Conclusion: PTH M determination of blood on the diagnosis of SHP has important clinical value, and monitoring of SHP have some reference value.
