Corrected Calcium
Routine annualalso albumin-adjusted calcium
What it isA calculation that adjusts total calcium for albumin level. Since most calcium binds to albumin, low albumin reduces total calcium even when the active ionized fraction is normal.
DoesProvides a more accurate estimate of calcium status when albumin is abnormal.
GoodMid-range corrected calcium signals truly intact calcium homeostasis.
BadSame patterns as total calcium, but with confounding from low albumin removed.
- Standard
- 8.6–10.3 mg/dL.
- Optimal
- 9.2–9.8 mg/dL (narrow target)
- Modifiers
- Only useful when albumin is abnormal; ionized calcium is more accurate when available.
How to optimize
- Lifestyle
- Same as total calcium.
- Diet
- Same as total calcium.
- Supplements
- Same as total calcium.
- Peptides
