Clinical Significance

Serum creatinine is useful in the evaluation of kidney function and in monitoring renal dialysis. A serum creatinine result within the reference range does not rule out renal function impairment: Serum creatinine is not sensitive to early renal damage since it varies with age, gender and ethnic background. The impact of these variables can be reduced by an estimation of the glomerular filtration rate using an equation that includes serum creatinine, age and gender.

eGFR= estimated Glomerular Filtration Rate
eGFR < 60 ml/min indicates the presence of chronic kidney disease. Lower doses of some drugs may be needed in patients with eGFR < 60.
eGFR<60: associated with increased risk of cardiovascular disease. Patients with eGFR <30 should be referred for renal consultation.
