A "bad" number for kidneys is generally considered to be an eGFR (estimated glomerular filtration rate) below 60 ml/min/1.73m2. This indicates that your kidneys are not filtering waste products from your blood as efficiently as they should.
- eGFR 60-90: This range may indicate stage G1 or G2 of chronic kidney disease (CKD).
- eGFR 30-59: Indicates stage G3 of CKD.
- eGFR less than 30: Indicates stages G4-G5 of CKD, which are the most severe.
An eGFR below 60 can be a sign of kidney disease, even if you have normal levels of protein in your urine. It's important to consult your doctor to discuss your eGFR results and to determine the cause of any abnormalities.
