Estimation of glomerular filtration rate among elderly patients

摘要

In the geriatric population, renal failure is one of the significant reasons of morbidity and mortality. Early detection and proper diagnostic classification are important. Using serum creatinine as a filtration marker is problematic; it is affected by other physiological processes, such as tubular secretion, generation and extra renal excretion. Other factors affecting creatinine generation are age, sex, race, diet and body habitus.
