Financial service providers market many different products as being available for nominal fees. A nominal fee is a payment or purchase price like any other fee. However, the use of the work nominal implies that the fee is small in comparison to the true value of what you can purchase with it.
Creatinine clearance in a healthy young person is about 125 milliliters per minute -- meaning each minute, that person's kidneys clear 125 mL of blood free of creatinine. The GFR can vary depending on age, sex, and size. Generally, the creatinine clearance is a good estimation of the glomerular filtration rate.
However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m 2 could be considered normal. Following the âprognostic wayâ, the fixed cut-off of 60 mL/min/1.73 m 2 has been retained in the K-DIGO guidelines.lso, more recently published studies presented lower GFR values as normal, i.e. at 100â110 mL/min/1.73 m 2 [ 3, 19, 21, 22, 24 â 26, 28 â 32 ] compared with prior studies published in the 1950s or before [ 2, 17, 18, 33 â 36 ].
