Will a 24 hr. urinalysis show if i have kidney failure?

Many tests!: Our bodies tend not to eliminate glucose or protein in our urine. When this happens, it may be due to diabetes or kidney disease. You will hear about creatinine - a breakdown product of muscle cells. When our kidneys are functioning normally, we eliminate creatinine in the urine. If kidneys are not working well, the creatinine increases in the bloodstream. Another blood test, the egfr, is useful.
