Sodium corrected for hyperglycemia
Hyperglycemia draws water extracellularly and dilutes sodium. Correction estimates sodium at normal glucose, informing fluid selection in ketoacidosis and hyperosmolar states.

Method · Limits of application
Katz 1973 factor 1.6 and Hillier 1999 factor 2.4 per 100 mg/dL glucose above 100
Hillier 1999 studied induced acute hyperglycemia in six healthy participants. The sodium–glucose relationship was nonlinear, especially above 400 mg/dL; the mean factor of 2.4 does not describe all populations and concentrations with universal accuracy. Katz 1.6 and Hillier 2.4 are distinct variants, presented separately. Corrected sodium is an estimate, not a guaranteed future measurement or a prescription for the correction rate.
Conditions of use
Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.
Documented parameters
