In a series of eight experiments attempts were made to change the levels of calcium in the blood of sheep by intravenous infusions of calcium, EDTA and thyrocalcitonin or changing the acid-base balance by various means. When total calcium levels changed these changes were mirrored closely by changes in the physiologically important ionized calcium fraction (r = 0.839). It is concluded that the total calcium determinations remain valuable indicators of changes in the physiological level of calcium in the blood.
在一系列八项实验中，通过静脉输注钙、乙二胺四乙酸（EDTA）和甲状腺降钙素，或通过各种方法改变酸碱平衡，试图改变绵羊血液中的钙水平。当总钙水平发生变化时，生理上重要的离子化钙部分的变化与之密切对应（r = 0.839）。得出的结论是，总钙测定仍然是血液中钙生理水平变化的重要指标。
