Data Source and Methodology
All calculations are based on the formula and data provided by Perinatology.com. The formula adjusts calcium levels based on albumin levels for accurate assessment.
The Formula Explained
Corrected Calcium = Serum Calcium + 0.8 * (4.0 - Serum Albumin)
Glossary of Variables
- Serum Calcium: The concentration of calcium in the blood.
- Serum Albumin: The concentration of albumin in the blood.
- Corrected Calcium: The adjusted calcium level accounting for albumin variation.
How It Works: A Step-by-Step Example
Input: Serum Calcium = 8 mg/dL, Serum Albumin = 3 g/dL
Calculation: Corrected Calcium = 8 + 0.8 * (4.0 - 3) = 8.8 mg/dL
Frequently Asked Questions (FAQ)
Why is corrected calcium important?
Corrected calcium provides a more accurate reflection of calcium levels in the presence of hypoalbuminemia, which is crucial for diagnosis and treatment.
When should I use this calculator?
Use this calculator when albumin levels are below normal, typically in patients with liver disease, nephrotic syndrome, or malnutrition.
What are normal serum calcium levels?
Normal serum calcium levels typically range from 8.5 to 10.2 mg/dL.
Can this calculator be used for children?
This calculator is intended for use in adults. Pediatric calculations may require different adjustments.
How does hypoalbuminemia affect calcium levels?
Hypoalbuminemia can lead to lower total calcium levels, as calcium binds to albumin in the blood.
