Bohr Model of the Atom (Explain what it shows and list one con for this model.) -Electrons orbit around the nucleus. -Each orbit has a fixed energy called an energy level. -To move from one energy level to another, an electron must gain or lose just the right amount of energy. -Each energy level has a different energy. -The further from the nucleus the energy level is, the more energy it has.
Because of this, creatinine tests measure the amount of creatinine in urine (for a creatinine urine test) or blood (in a serum creatinine test) and use this information to determine whether the kidneys are functioning normally.
A simple âdipstickâ test may be used to detect excess protein in the urine. 1  Serum Creatinine: Creatinine is a waste product in your blood that comes from muscle activity. 2  Glomerular Filtration Rate (GFR): Your GFR tells how much total kidney function you have. 3  Urine albumin.  Urine albumin-to-creatinine ratio.
