6. why measure GFR?

  • identifying & diagnosing renal disease, monitoring genetic progression
  • identifying & diagnosing renal disease, monitoring disease progression
  • identifying & diagnosing renal and cardiovascular disease, monitoring disease progression

7. what is inulin

  • inert, dietary polysaccharide
  • inert, dietary monosaccaride
  • inert, dietary disaccaride

8. what is creatinine

  • breakdown product of muscle creatine
  • breakdown messenger of muscle creatine

9. Renal clearance definition (ml/min)

  • volume of bile from which all trace of a substance is removed per unit time;
  • volume of plasma from which all trace of a substance is removed per unit time
  • volume of urine from which all trace of a substance is removed per unit time;
  • volume of nephrons from which all trace of a substance is removed per unit time;

10. what are GFR algorithms dependent on

  • finding a stable plasma creatinine value
  • finding a stable plasma insulin value
  • finding a stable plasma inulin value
  • finding a stable plasma creatine value

11. why can these GFR algorithms be problematic?

  • variable plasma creatinine levels e.g muscle gain
  • variable plasma inulin levels e.g muscle gain

12. how is renal plasma flow (RPF) measured

  • by determining the renal clearance of p-aminohippuric acid (PAH).
  • by determining the renal clearance of p-aminohipporic acid (PAH).
  • by determining the renal clearance of l-aminohippuric acid (LAH).

13. what can be used as a substitute for renal clearence measurements

  • GFR algorithms
  • RPF algorithms
