Calcium, Corrected for Albumin
Corrected calcium is a calculated adjustment to your total calcium that accounts for your albumin level. Because much of your calcium travels bound to albumin, low albumin can make total calcium look lower than it truly is.
The correction helps estimate your true calcium status when albumin is abnormal, giving a more accurate read without needing a separate ionized calcium test. It's a common adjustment your lab or clinician may apply.
A high corrected calcium suggests genuinely elevated calcium even after accounting for albumin, which your clinician may investigate further. It remains an estimate, and ionized calcium can confirm if needed.
A low corrected calcium suggests calcium is truly low rather than just appearing low from reduced albumin, and is interpreted with your overall picture.
Targets mirror total calcium, roughly 8.5 to 10.2 mg/dL after correction. Your clinician can confirm what applies to you.
