When do you consider calcium deficiency?
Calcium is one of the body minerals with a narrow range of normal levels. A subtle increase or decrease affects the body massively. Calcium blood tests measure both ionized calcium (free calcium) and non-ionized calcium (bound to protein). Normal calcium levels range from 8.5 to 10.5 mg/dl.
Low calcium levels show two types of tetany:
- Latent tetany: 7.5 to 8.5 mg/dl
- Manifested tetany: below 7.5 mg/dl.
