Introduction
The normal value of glomerulus refers to the normal range of glomerular filtration rate (GFR). For adults and children over 2 years of age, the normal range is 90–120 ml/(min·1.73m²). For newborns, it is approximately 20–30 ml/(min·1.73m²); for children aged 6–12 months, it is about 60–90 ml/(min·1.73m²).
Glomerular normal values refer to the normal range of glomerular filtration rate (GFR). In general, for adults and children over 2 years old, the normal range is 90–120 ml/min. However, normal values vary somewhat with age, as detailed below:
Glomerular filtration rate is one of the most commonly used clinical indicators to assess an individual's kidney function. It also helps determine whether a person has acute kidney injury, chronic kidney disease, diabetic nephropathy, or other renal disorders. Under normal circumstances, the GFR for adults and children over 2 years of age ranges from 90 to 120 ml/min; in newborns, the normal value is about one-quarter that of adults, approximately 20–30 ml/min; for infants aged 6–12 months, the normal value reaches about three-quarters of that in adults, roughly 60–90 ml/min.
A glomerular filtration rate outside the normal range is considered abnormal. However, it should be noted that during pregnancy, GFR physiologically increases—by around the third month of gestation, it may rise by approximately 50% compared to normal levels—and gradually returns to the normal range after delivery. If the cause of an elevated GFR is unclear, it is advisable to seek timely medical evaluation.
