Use Corrected Sodium when you need to correct measured serum sodium for hyperglycemia with the 1.6 per 100 mg/dL rule. Enter Glucose and Measured sodium using the definitions and units below so the result can be reproduced.

Glucose

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

Measured sodium

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

The published tool contract uses this rule: Correct measured serum sodium for hyperglycemia with the 1.6 per 100 mg/dL rule.^[1]

Corrected sodium

The calculated corrected sodium in mmol/L.

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

Retain the original Glucose and Measured sodium values and their units alongside the result. Corrected Calcium is useful when you instead need to adjust measured calcium for hypoalbuminemia with the 0.8 correction. Phenyl Tyrosine Ratio provides another view by helping you compute the phenylalanine to tyrosine concentration ratio in micromoles per litre.

• Corrected Calcium

  Adjust measured calcium for hypoalbuminemia with the 0.8 correction.

• 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.
