What it generally measures
Labs typically report total calcium in blood, which is influenced by bone, diet, vitamin D status, and other factors that a clinician can help interpret.
Common units on reports: mg/dL
Why people track it over time
Calcium is often reviewed alongside albumin (since a low albumin can lower total calcium readings) and other metabolic markers.
