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.
The urine 24-hour volume test measures the amount of urine produced in a day. The amount of creatinine, protein, and other chemicals released into the urine during this period is often tested. For this test, you must urinate into a special bag or container every time you use the bathroom for a 24-hour period. 1  On day 1, urinate into the toilet when you get up in the morning.  Afterwards, collect all urine in a special container for the next 24 hours.
