Glomerular filtration rate refers to the rate of blood flow through the kidneys. The glomeruli are microscopic bundles of blood vessels inside nephrons and are crucial parts of the filtering system.
A normal estimated GFR for adults is greater than 90 mL/min/1.73m2.
Estimated GFR<60 mL/min/1.73m2 may indicate
- Kidney damage
- Chronic kidney disease
- Cerebrovascular disease
- Chronic obstructive pulmonary disease (COPD)
- Coronary heart disease
- Heart failure
- Liver disease
It should be noticed that estimated GFR> 90 mL/min/1.73m2 may also indicate some kidney damage. Thus, a person’s eGFR should be interpreted in relation to the person’s clinical history and presenting conditions.
