My lab reports are serum creatinine 80, gfr 72, and creatinine clearance 69.9. my 24 hr urine creatinine was 6.9 and spot urine 2.2. what does it mean?

Not much: You're 55 years old and -- congratulations -- a recovered problem drinker. Unless you're especially fit or heavily-muscled, your creatinine may be a bit high and maybe your kidneys are getting old -- but this level is perfectly compatible with good health and if you had serious kidney disease, it would be a lot worse by now. Eat sensibly, stay fit and I bet your kidneys will last a lifetime.
