Title: Method for assessing functional reserve of kidneys
Inventor: NESEN ANDRII OLEKSIIOVYCH
Filed: 2001-07-10
Abstract: The method for assessing the functional reserve of the kidneys consists in estimating the basal glomerular filtration rate and the maximal glomerular filtration rate upon intravenous administration of the stimulating protein substance containing L-amino acids. Then the ratio of the functional reserve is calculated. If the ratio exceeds 10%, the functional reserve is preserved. The ratio in the range of 5-10% points to the reduced functional reserve. The ratio below 5% suggests that the functional reserve is depleted.
