One hundred cases of hypophosphataemia (</= 2.0 mg/100 ml) and 84 cases of hyperphosphataemia (>/= 5.0 mg/100 ml) occurring in a hospital population were studied in order to determine the cause of the abnormality. Examples of hyperphosphataemia due to renal failure were excluded from the study.A low serum phosphorus concentration was most frequently due to intravenous administration of carbohydrate, usually glucose, which accounted for 40% of cases. The next commonest cause was vomiting (12%). No obvious explanation could be found in 26% of cases, but in most of these factors were present which are known to affect phosphorus metabolism.No one cause of hyperphosphataemia was outstanding in frequency and in over 50% of cases no definite explanation for the abnormality could be found.
为了确定异常原因，对某医院人群中出现的100例低磷血症（≤2.0mg/100ml）和84例高磷血症（≥5.0mg/100ml）进行了研究。本研究排除了因肾衰竭导致的高磷血症病例。血清磷浓度低最常见的原因是静脉输注碳水化合物，通常是葡萄糖，占病例的40%。其次最常见的原因是呕吐（12%）。26%的病例找不到明显原因，但其中大多数存在已知会影响磷代谢的因素。没有一种高磷血症的原因在出现频率上突出，超过50%的病例对这种异常找不到明确原因。
