What This Value Measures
Calcium is a mineral that is important for bones, muscles, and nerves. The blood level is closely regulated by various hormones. Usually, total calcium is measured, which also depends on the protein albumin in the blood.
Elevated Value
An elevated value may indicate, among other things, overactive parathyroid glands or other causes.
Low Value
A decreased value may be associated with vitamin D deficiency or disturbances in calcium metabolism.
Note: The total calcium value is influenced, among other things, by the albumin level. Therefore, in the case of abnormal values, it is advisable to assess it together with albumin or to determine the ionized calcium.
Reference ranges are typical guide values for adults and vary depending on the laboratory, measurement method, age and sex — always compare with the range stated on your own report. A value outside the range does not automatically mean an illness, and a value within the range does not rule one out. The trend and overall picture are usually more informative than a single value. The doctor's assessment is always decisive.
