Calcium
What it measures
Calcium supports bone strength, muscle function, and nerve signaling, and circulates in your blood in tightly controlled amounts.
Often reported in mg/dL. Reference ranges differ between laboratories, ages and sexes, so always compare with the range printed on your own report.
Why it matters
Blood calcium is regulated by hormones and can be affected by protein levels in the blood, diet, and certain medications.
Questions worth asking
- Should this be interpreted alongside an albumin level?
- Could a supplement or medication be contributing to this result?
- Is further testing of related hormones worth discussing?
