My kidney function shows a low estimated gfr level. what should i do?

See a specialist: A low GFR usually indicates decreased kidney function. This may be a normal part of aging as we all lose some kidney function over time. The treatment and evaluation of someone with a low GFR depends on the stage of kidney failure (which is determined by the gfr) and other risk factors (diabetes, hypertention, etc). If the GFR is low (less than 60), i would recommend seeing a kidney specialist.

See below: You should consult with a nephrologist to try and determine the cause.Low GFR means loss of kidneys ability to remove waste from the body, and there are many causes and possibility of reversibility or management of preventing further decrease in fucntion is important.

See Nephrologist: Depending on how low, and assuming it is a new finding (sounds like it), you should consult a kidney specialist to try to identify what is going on to prevent its worsening and hopefully improve it.

Low GFR level: You should ask your doctor to order a 24 hour urine for creatinine clearance and have blood taken when you drop off the urine at the lab. That is the way you will get an actual rather than an estimated gfr.
