Renal aging is frequently confused with chronic nephropathy in clinical practice, since there are some similarities between them, particularly regarding reduced glomerular filtration rate (GFR). However, there are many differences between these two entities which can help any practitioner to distinguish between them, such as: GFR deterioration rate, hematocrit, renal handling of urea, creatinine and some electrolytes, tubular acidification, urinalysis, and renal imaging. Differentiation between renal aging and chronic renal disease is crucial in order to avoid unnecessary medicalization of what is a physiological change associated with the healthy aging process, and the potential harmful consequences of such overdiagnosis. A recently described equation (HUGE), as well as an adequate nephrological evaluation and follow up can help physicians to distinguish both entities.
