Hi Joan.... GFR is a kidney function test it has to do with how the body is filtering creatinine.
normal rate is about 90 .. 110ml.per min (not totally sure of that tho...so possibly look it up by googling GFR ......... a low rate would usually mean some type of problem with the kidneys.
Best to talk with your doc that ran the test about this...
this was on wikipedia
All individuals with a Glomerular filtration rate (GFR) 60 mL/min/1.73 m2 is that GFR may be sustained at normal or increased levels despite substantial kidney damage and that patients with kidney damage are at increased risk of the two major outcomes of chronic kidney disease: loss of kidney function and development of cardiovascular disease.
The loss of protein in the urine is regarded as an independent marker for worsening of renal function and cardiovascular disease. Hence, British guidelines append the letter "P" to the stage of chronic kidney disease if there is significant protein loss.
Slightly diminished function; kidney damage with normal or relatively high GFR (≥90 mL/min/1.73 m2). Kidney damage is defined as pathologic abnormalities or markers of damage, including abnormalities in blood or urine test or imaging studies.
Mild reduction in GFR (60-89 mL/min/1.73 m2) with kidney damage. Kidney damage is defined as pathologic abnormalities or markers of damage, including abnormalities in blood or urine test or imaging studies.
Moderate reduction in GFR (30-59 mL/min/1.73 m2). British guidelines distinguish between stage 3A (GFR 45-59) and stage 3B (GFR 30-44) for purposes of screening and referral.
