What causes high Calcium and low MCV?

High Calcium and low MCV can be caused by many reasons.

If your Calcium is in between 8.5 mg/dL and 10.1 mg/dL and your MCV is in between 83 fL and 101 fL then you need not worry as these are the normal ranges for Calcium and MCV respectively. But if your levels are lesser or greater than the above values, then there may be some problem in your body.

Some examples of conditions that can increase or decrease Calcium levels include:

• Overactive parathyroid glands
