  2. when is indicative when urine is cloudy
    there are a significant # of WBC's present
  3. what should the biochemical test for wbc esterase be if 6-15 granulocytes per field are seen in high power
    positive if granulocytes and monocytes present(neg if lymphocytes present)
  4. how many fields should be used to count cells in a urine
    ten fields at high power
  5. what is increased number of wbcs indicative of
    infection or inflammation
  6. if bacteria is present as well as increased wbc what could this be indicative of
    infection of the kidney(pyelonephritis),bladder(cysititis), or urethra(urethritis)
  7. what impact rbc apperance in urine
    urine concentration (causes biconcave, oval, or round rbcs)
  8. how many rbcs must be present per field to be considered abnomal
    greater than 2-3 per high power field
  9. why might rbcs be seen in urine
    due to menstrual contamination or injury or disease of any portion of the urinary tract
  10. what color will urine be if a significant # of rbcs are present
    red or brown and cloudy
  11. how many rbcs are seen in a normal urine
    0-3 rbcs
  12. what type of epithelial cells may be indicative of disease if seen in large #'s
    transitional or renal tubular
  13. large #'s of sqaumous epithelial cells are may be indicative of what in a female
    vaginal contamination during collection
  14. what are oval fat bodies
    renal tubular epithelial cells that contain lipids

    nephroitic syndrome
  16. if the fat present in oval fat body is cholesterol what do the fat droplets form
    maltese cross
  17. what power is cast observed under
    low power
  18. what are hyaline cast composed primarily of
    simple TammHorsfall protein
  19. why might a cast appear yellow
    due to the bilirubin in the urine

    envelope, dumbbell, ovoid, or rectangular shaped
  25. describe the appearance of calcium phosphate crystals
    large flat shaped plates or wedged-shaped prisms which appear in rosettes if singly appear flat on one end and pointed on the other
  26. describe the appearance of triple phosphate crystals
    coffin-lid shaped or fern leaf shaped(due to freshly newly formed)
  27. describe the appearance of calcium carbonate crystals
    seen as granules or dumbbells and may appear as a large aggregates or single form
  28. what do ammonium biruate usually indicate
    old or poorly preserved specimen
  29. describe the appearance of ammonium biruate crystals
    thorny apple shaped and yellowish brown
