Normal and Abnormal Calcium Levels | UCLA Endocrine Center

Blood tests are often a part of an annual physical exam, and one of the components they measure is the amount of calcium in your blood. Most people have a calcium level in the 8-10 range, but this can vary, says endocrine surgeon Masha Livhits, MD.

If your calcium levels are too low, you could have vitamin D deficiency, trouble absorbing calcium from your diet or kidney problems. If your calcium level is high, your doctor will likely recheck it to ensure it wasn’t a lab error. At UCLA Health, any calcium level above 10.4 is considered high. If your calcium levels are still high after a recheck, more blood tests are needed to determine the cause.
