normal values / reference ranges Flashcards
inulin clearance of male
125 ml/min
inulin clearance of female
115 ml/minaverage: 120 ml/min
PAH clearance
600 - 700 ml/min
serum osmolality normal range
285 - 319 mOsmol/kgH2O
serum osmolality- serum- urine 24h- urine/serum- random urine- osmolal group
- serum = 275-295- urine 24h = 300-900- urine/serum = 1.0-3.0- random urine = 50-1200- osmolal group = 5-10
delta osmolality that indicates poor prognosis
> 400 mOsmol/kgH2O
RFI/FeNa that indicates pre-renal failure
<1.0
positive for free water clearance indicates?
urine is diluted compared to serum
negative for free water clearance indicates?
urine is concentrated compared to serum
