renal labs Flashcards
Serum creatinine
0.5 - 1.2
increase in renal failure
decrease in muscle mass loss, meds like antibiotics
BUN
8 - 21
increased in renal failure, liver disease, dehydration, infection, high protein diet
decreased in severe liver damage, malnutrition, consumptions of low protein diet, excess fluid
BUN/Creatinine ration
10:1 - 20:1
increase hypovolemia and hypotension
decrease in fluid excess
Uric Acid
3.5 - 8
increase in renal failure, malnutrition,
decrease in burns, pregnancy, wilsons diseas
bicarb
24 - 28
increase in vomiting, gastric suction, excess loss of potassium
decrease in renal failure
sodium
135 - 145
decrease because of excess fluid
potassium k
3.5 - 5
increase (usually noticeable early)
phosphorus po4
2.5 - 4.5
increase
calcium
8.2 - 10.2
decrease
specific gravity of urine
1.005 - 1.030
increase diabetes, dehydration, fever
decrease kidney failure, diabetes insipidus, diuretic use
osmolality of urine
250 - 900
increase in diabetes, dehydration, fever
decrease kidney failure, diabetes insipidus, diuretic use
protein of urine
2 - 8
persistently increased is renal insufficiancy
glucose in urine
above 200 is a renal insufficiency
creatinine clearance
85 - 135
decrease is renal impairment
