The normal glomerular filtration rate ranges from 80 to 120 ml/(min-1.73 m²).
Normal adult blood flow through the kidneys per minute for 1200 ~ 1400ml, of which the plasma volume of 600 ~ 800ml/min, 20% of the plasma by glomerular filtration, resulting in filtrate (primary urine) is about 120 ~ 160ml / min, that is, the amount of plasma liquid per unit of time by the glomerular filtration is known as the glomerular filtration rate.
Clinical glomerular filtration rate is often obtained by determining the more stable endogenous metabolites (e.g. creatinine) or exogenous (e.g. inulin) within the plasma, which can be freely filtered without (or to a small extent) reabsorption through the renal tubules, and the current reference range for the normal glomerular filtration rate in the clinic is 80 ~ 120ml/(min-1.73m2).
The main function of the glomerulus is filtration, and the most important parameter for assessing filtration function is the glomerular filtration rate (GFR).The GFR is also related to age, and reaches its peak at the age of 25-30 years, and thereafter decreases gradually with age.
It is recommended that patients with abnormal glomerular filtration rate should go to the relevant departments of the hospital in time, and under the guidance of professional doctors, improve the relevant examinations, so as to clarify the diagnosis of the disease and receive standardized treatment.
