Glomerular filtration rate refers to the amount of filtrate produced by the two kidneys per unit of time, and a glomerular filtration rate (GFR) of 87.7 ml/min is considered to be in the normal range, with a normal adult being around 80 to 120 ml/min. Glomerular filtration rate and filtration fraction are indicators of renal function. Normal values are (80-120) ml/min for men and about 10% lower for women, and they are used to understand the situation of renal hypoplasia. Increased glomerular filtration rate can be seen in physiological conditions or pathology, such as diabetic nephropathy in the early stage; glomerular filtration rate can be increased during pregnancy, and return to normal after delivery. Decreased glomerular filtration rate is usually seen in a variety of primary and secondary renal diseases that affect glomerular filtration function, and it also decreases with aging. It is recommended that patients with abnormal glomerular filtration rate should consult a doctor in time to find out the cause of the abnormality and standardize the treatment under the doctor’s guidance.
