Clinical takeaway
Low albumin lowers total but not ionised calcium.
When to use
Interpret calcium in hypoalbuminaemia.
How it works
Corrected Ca = measured Ca + 0.8 × (4.0 − albumin g/dL). Reference 8.5–10.5 mg/dL.
Key points
- Low albumin lowers total but not ionised calcium.
- Ionised calcium is more reliable in critical illness.
- Correct before judging hypo-/hypercalcaemia.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Measured total calcium | 8.0 mg/dL |

FAQ
Frequently asked questions
- What are the limits and cautions when using Corrected Calcium (Albumin)?
- For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
- Does Corrected Calcium (Albumin) upload patient data? Where is it calculated?
- Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
- How is Corrected Calcium (Albumin) calculated in practice? Can you show a worked example?
- Inputs: Measured total calcium 8.0 mg/dL, Albumin 2.0 g/dL → Result: Corrected calcium 9.6 mg/dL（Reference: 8.5–10.5 mg/dL, Formula: Ca + 0.8 × (4.0 − albumin)）
