pH ->
renal tubular absorption/secretion problem
blood ->
hematuria
hemoglobinuria
myeloglobinuria
specific gravity ->
low: diabetes insipidus
high: adrenal insufficiency, hepatic disease, congestive heart failure, dehydration
ketone ->
diabetes mellitus; inadequate intake/loss of carbohydrates
bilirubin
hepatic or post hepatic conditions
glucose
diabetes melltius, hormone disorders, end stage renal disease
hematuria
presence of intact RBC
hemoglobinuria
presence of free hemoglobin - indicates RBC lysis
myoglobinruia
presence of myeoglobin indicates muscle destruction
example of hematuria
- renal calculi
- glomerulonephritis
- pyelonephritis
- tumors
- trauma
- exposure to toxic chemicals
- anticoagulants
- strenous excercise
example of hemoglobinuria
- transfusion reactions
- hemolytic anemias
- severe burns
- infections/malaria
- strenous excercise
- brown spider bite
