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.
A low GFR or creatinine clearance demonstrates kidney disease. The decline in kidney function can be either acute (sudden, often reversible) or chronic (long-term and irreversible). Repeated GFR or creatinine clearance measurements over time can identify kidney disease as acute or chronic.tage 3: GFR 30-59 (moderate decline in kidney function). Stage 4: GFR 15-29 (severe decline in kidney function). Stage 5: GFR less than 15 (kidney failure, usually requiring dialysis). People over age 60 may have an apparently normal creatinine blood level, but still have a low GFR and creatinine clearance.
