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.
Normal Creatinine Levels in Urine. Creatinine comes from your body's everyday use of your muscles -- and also from eating meat. As blood flows through the kidneys, creatinine is excreted out into your urine along with other waste products.Levels of creatinine in the urine taken over 24 hours, together with blood levels of creatinine, can be used to estimate the rate at which your kidneys do their filtering job.hat is normal for you may be different than what is normal for someone else. People who eat a lot of red meat will have higher urinary creatinine levels than vegetarians. But for them, this higher level is still normal. Urine creatinine levels also reflect the amount of muscle mass you have.
