Calcium correction calculator for hypoalbuminemia in conventional or SI units
Posted by dkwinter

Serum calcium concentration correction calculator (for hypoalbuminemia)

Serum calcium: mg/dL OR
Serum albumin: g/dL OR

Corrected serum calcium concentration=

(Based on a normal serum albumin value of 4 g/dL)



Reference ranges:

     Albumin: 35-50 g/L (3.5-5 g/dL)

     Calcium: 2.25-2.75 mmol/L (9.0-10.5 mg/dL)

     Ref: Mosby's Canadian Manual of Diagnostic and Laboratory Tests, 1st ed.


Calcium correction formula:

     Calcium (in mg/dL) = Patient's calcium (in mg/dL)  + 0.8 * [Normal albumin (in g/dL) - Patient's albumin (in g/dL)]
