| Test background |
Electrolytes are usually measured as part of a renal profile, which measures sodium, potassium, creatinine and urea. Creatinine is almost completely filtered by the kidneys and increasing serum concentrations correspond with a worsening of the glomerular filtration rate as a function of encroaching kidney failure. |
