Use Corrected Calcium when you need to adjust measured calcium for hypoalbuminemia with the 0.8 correction. Enter Measured calcium and Albumin using the definitions and units below so the result can be reproduced.

Measured calcium

A finite measured or assumed value greater than or equal to 0, expressed in mg/dL.

Albumin

A finite measured or assumed value greater than or equal to 5e-324, expressed in g/dL.

The published tool contract uses this rule: Adjust measured calcium for hypoalbuminemia with the 0.8 correction.^[1]

Corrected calcium

The calculated corrected calcium in mg/dL.

The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.

Retain the original Measured calcium and Albumin values and their units alongside the result. Corrected Sodium is useful when you instead need to correct measured serum sodium for hyperglycemia with the 1.6 per 100 mg/dL rule. Phenyl Tyrosine Ratio provides another view by helping you compute the phenylalanine to tyrosine concentration ratio in micromoles per litre.

• Corrected Sodium

  Correct measured serum sodium for hyperglycemia with the 1.6 per 100 mg/dL rule.

• Phenyl Tyrosine Ratio

  Compute the phenylalanine to tyrosine concentration ratio in micromoles per litre.

• Corrected Retic Percent

  Correct the reticulocyte percent for anemia by multiplying by the patient to normal hematocrit ratio with a reference normal hematocrit of 45 percent.
