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.
Highlights. 1  Creatinine is a chemical waste product thatâs normally filtered out of your blood by your kidneys. When your kidneys arenât functioning properly, creatinine can accumulate in your body. 2  A urine 24-hour volume test is the most common type creatinine urine test.
