骨质疏松症最主要的病因为高龄、闭经等,其生化学检查所见也随高龄而产生在生理范围内的波动。因而,该症的特征之一是生化学检查无异常所见。本文仅就骨质疏松症(闭经后、老年性)的血清生化学检查做一概述。一、血清Ca与P 骨质疏松症的血Ca、P及ALP(碱性磷酸酶)等一般血清生化学检查均正常。成人男女都有随年龄增长血Ca逐渐下降的趋势,但40～50岁的女性闭经后都呈现略微上升的趋势。Ca离子和血清总钙浓度变动倾向相同。一般认为,骨质疏松症的血Ca变动与这种由于高龄而引起的血Ca浓度变动几乎无差异。据厚生省老年性骨质疏松症研究班制定的骨质疏松症诊断标准,血清Ca、P、ALP均在正常范围。如果生化学检查所见异常,则应考虑其他代谢性骨疾患。血清中的钙是由蛋
Osteoporosis is the most important causes of advanced age, amenorrhea, etc., the biochemical tests also see with older age and produce fluctuations in the physiological range. Therefore, one of the characteristics of the disease is no abnormal biochemical findings. This article only on osteoporosis (amenorrhea, senile) serum biochemical examination to make an overview. First, the serum Ca and P osteoporosis blood Ca, P and ALP (alkaline phosphatase) and other general serum biochemical tests were normal. Adult men and women have a gradual decline in serum Ca with age trend, but 40 to 50-year-old women showed a slight upward trend after menopause. Ca ion and serum total calcium concentration tended to change the same. It is generally considered that there is almost no difference in the change of blood Ca in osteoporosis and the change in blood Ca concentration caused by aging. According to the diagnostic criteria for osteoporosis developed by the Health and Welfare Bureau of Senile Osteoporosis, serum Ca, P and ALP levels are in the normal range. If the biochemical examination of abnormalities, you should consider other metabolic bone disorders. Serum calcium is made from eggs
