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
