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 is a by-product of muscle metabolism. that is excreted in the urine. Its measurement is routinely used. clinically to evaluate kidney function. Additionally, urinary creati-. nine determination is an important parameter for evaluating the. validity of a urine specimen for drugs of abuse detection. Because.
