Alkaline phosphatase was measured in plasma from children receiving vitamin D supplements in day nurseries in the London area, and from children exposed to sunlight in the West Indies. The distribution of values showed that there was no precise upper limit which could be used in the diagnosis of subclinical vitamin D deficiency.
对伦敦地区日托所中接受维生素D补充剂的儿童以及西印度群岛接受阳光照射的儿童的血浆碱性磷酸酶进行了测量。测量值的分布表明，没有可用于诊断亚临床维生素D缺乏症的确切上限。
