Question: is a gfr of 37 bad?
Answer: even a gFR over 90 with protein in the urine is a sign of kidney disease. gFR must remain low for three months for CKd to be diagnosed. when gFR is below 60 for more than three months, this is moderate-to- severe chronic kidney disease. you may be referred to a nephrologist (kidney doctor) for evaluation and treatment.
