    man normal urine pH
  37. proteinuria
    abnormal levels of protein in the urine, false positives found in alkaline urine
  38. glucosuria or glycosuria
    glucose in the urine, normal urine is negative, acetaminophen will cause false positives
  39. acetone, acetoacetic acid, beta-hydroxybutyric acid
    three types of ketones, normals animals have small amounts
  40. hematuria, hemoglobinuria, myoglobinuria
    tests for blood in the urine detect these
  41. hematuria

  42. hemoglobinuria
    the presence of free hemoglobin in the urine (the separation of hemoglobin from the RBC)
  43. myoglobinuria
    the presence of myoglobin in the urine, caused by muscle damage
  44. bilirubinuria
    bilirubin in the urine, normal in dogs, can be detected with the Ictotest, false negative from exposure to sunlight
  45. 5ml for 3-5 min at 1000-2000rpm

    normal and abnormal WBC's found in the urine
  52. squamous, transitional, renal

  53. 0-1/HPF
    transitional epithelial cells normal range, increased numbers suggest cystitis or pyelonephritis

    renal epithelial cells normal range, increased numbers indicate kidney disease
  55. casts
    formed in the lumen of the distal and collecting tubules of the kidney, abnormals levels indicate a lesion on the renal tubules

    appear deep yellow or orange, indicates bleeding from the kidney
  61. waxy casts
    resemble hyaline casts but wider and with square ends, indicates chronic and severe degeneration of the renal tubules
