What is a normal GFR for a 70 year old?

Following the classical way, we can assert that normal GFR values are largely over 60 mL/min/1.73 m2 in healthy subjects, at least before the age of 70 years. However, we know that GFR physiologically decreases with age, and in adults older than 70 years, values below 60 mL/min/1.73 m2 could be considered normal.

Water ingestion can acutely affect GFR, although not necessarily in the direction one might expect. Using 12 young, healthy individuals as their own controls, Anastasio et al. found increased water intake actually decreases GFR.

Is 50 percent kidney function bad?

As normal eGFR is round about 100, the eGFR gives you an approximate ‘percentage function’. So if your eGFR is 50, your kidneys are probably filtering at about 50% of normal. It’s very approximate though, and there are times when it can’t be very reliable at all.

How accurate is eGFR?

Precision of eGFR is poor at levels of mGFR >60 ml/min per 1.73 m2 (1 SD = 21 ml/min per 1.73 m2) but gradually improves (in absolute but not in relative terms) as the mGFR declines. For an mGFR between 30 and 59 ml/min per 1.73 m2, the precision of eGFR-MDRD is still poor at 13 ml/min per 1.73 m2 (1 SD).
