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.
Clinical Indications Suspected renal failure (acute/chronic) Monitoring of patients receiving intravenous fluids Monitoring of established chronic kidney disease
Reference Range Adult male: 60-125 μmol/L Adult female: 55-110 μmol/L Less than 7 days: 30-100 μmol/L 7-21 days: 30-80 μmol/L 21 days-2 years: 20-60 μmol/L 2-5 years: 20-70 μmol/L 5-10 years: 30-80 μmol/L 10-16 years: 40-100 μmol/L
