A 37-year-old member asked:
Low creatinine on a urine test, what caused that?

Several things: The most likely is inadequate collection of urine such that some of the 24 hour sample was discarded. Other causes are low muscle mass, which can occur in very small stature people, advanced age, bed bound individuals, and in patients with cirrhosis.
