trigger - hematuria Flashcards
if RBCs in urine microscopy are dysmorphic what does this mean
likely d/t glomerular disease
if RBCs in urine microscopy are normal and round what does this tell you
they are likely d/t urinary tract epithelial disease/damage
glomerulonephritis and vasculitis can both cause what
RBC casts
WBCs, epithelial cells and bacteria can cause false positives of what urine marker?
protein in urine
injury to the urinary tract is suggested by the presence of what in the urine microscopy
WBCs
inflammation of the kidney such as during acute pyelonephritis and interstitial nephritis is indicated by the presence of what marker in the urine microscopy
WBC casts
increased shedding of epithelial cells suggests whatcondition
nephrotic syndrome or tubular degeneration
when are oval fat bodies, maltese crosses or grape clusters seen on urine microscopy
when lipiduria occurs
semen in the urine or vigorous exercise can cause false positive for what UA test
heme dipstick test
also:
menstrual blood in urine
concentrated urine
neoplasm is indicated by presence of what type of cells
transitional epithelial cells
CT urography is imaging of choice for what
evaluation of upper tracts for sources of hematuria
what is cystoscopy used for in evaluation of hematuria
evaluation of lower tracts for source of hematuria
phenazopyridine, rifampin, gluycosuria and high urine specific gravity are all things that could cause false negatives of what UA test
leukocyte esterase
phenazopyridine also can cause false POSITIVE in bilirubin
renal damage is indicated by the presence of which urine cytology finding
granular casts
hemolysis and hepatocellular disease can incease what UA marker
urobilinogen
