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 information below is meant to provide an overview of these tests. Your doctor will counsel you regarding the results of your personal blood work and laboratory tests. Kidney Function Tests. The creatinine blood test and blood urea nitrogen (BUN) test are used to assess kidney function in people with lupus kidney disease (nephritis).
