Q: How much protein is lost through urine by a healthy man everyday? Are protein and albumin the same things?

A:Most studies done on healthy individuals have shown that up to 30 mg/day of protein in urine is normally excreted and is physiological. Broadly speaking, proteins are of two different kinds: albumin and globulin. Albumin is the major form of protein excreted in urine under usual condition and diseases such as diabetic kidney failure. However, certain diseases result in excessive amount of globulin excreted in urine.
