Lab Ex 57: Urinalysis

Lab Ex 57: Urinalysis. pH = 4.6 – 8.0. Normal pH is within this range Average = 6. Specific Gravity = 1.003 – 1.035. Normal SG is within this range This is the “density” of the liquid. Water = 1.000 1.003 = dilute 1.035 = concentrated. Urochrome / urobilin.

Presentation Transcript

  1. Lab Ex 57: Urinalysis

  2. pH = 4.6 – 8.0 • Normal pH is within this range • Average = 6

  3. Specific Gravity = 1.003 – 1.035 • Normal SG is within this range • This is the “density” of the liquid. • Water = 1.000 • 1.003 = dilute • 1.035 = concentrated

  4. Urochrome / urobilin Oxidized form of urobilinogen, which is yellow and causes normal urine color

  5. Unorganized sediments (crystals)

  6. Renal calculus

  7. Organized sediments

  8. WBCs (pus) An occasional WBC is normal Both of these samples are abnormal

  9. RBCs An occasional RBC is normal Both of these samples are abnormal

  10. Epithelial cells Usually normal

  11. Casts Waxy = renal failure Granular = cause varies Hyaline = usually normal

  12. Centrifuge

  13. Urine dipsticks

  14. Urinometer

  15. Sedi-stain
