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.
Creatinine can be tested in both the blood and in the urine. These tests can help evaluate kidney function. Serum creatinine is a test that draws blood and sends it to a laboratory to be analyzed to find out how much creatinine is in the bloodstream. Knowing your serum creatinine allows your doctor to calculate your creatinine level along with your age, gender and race, to determine your glomerular filtration rate (GFR).
