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 albumin-creatinine ratio in early morning spot urine collected on awakening (before breakfast or exercise) is considered as a valid test for albumin excretion in urine. It is simple and inexpensive; it does not require a timed 24-hour collection of urine; and, most importantly, it gives a quantitative result that correlates well with 24-hour urine values over a wide range of protein excretion.
