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.
It enters the bloodstream and is filtered by the kidneys to get excreted through the urine. A blood creatinine test will measure the amount of creatinine in your blood. A higher level (greater than 0.8-1.2 mg/dl in men and 0.6-0.9 mg/dl in women) may indicate that the kidneys are not functioning properly. 3. Blood urea test: Urea is a waste product filtered by the kidneys and excreted through the urine.
