The egfr is the estimated glomerular filtration rate and 86.3ml is normal and not serious. Glomerular filtration rate is the amount of filtrate produced by the two kidneys in one minute per unit of time, which is about 80-120 ml per minute in normal adults. the ratio of the glomerular filtration rate to the renal plasma flow rate is called the filtration fraction, and about one-fifth of the plasma that passes through the kidneys is filtered by the glomeruli into the capsule, where it produces the primary urine. A high glomerular filtration rate is common in early diabetic nephropathy. If the value is low it is common in glomerulonephritis, hypertension and kidney injury. When glomerular filtration rate is below 60, creatinine and urea are seen in IgA-induced kidney damage. However, if the value is at 86.3 ml, it is a non-serious state. By testing serum creatinine and calculating glomerular filtration rate based on age, gender and weight, a glomerular filtration rate of 86.3 ml is within the normal range. If it is out of the normal range, too low or too high, you need to see a doctor in time to find out the cause of the disease and diagnose and treat it in time to avoid deterioration of the disease.
