The CDC guidelines recommend that the following tests and findings be used to help diagnose acute epididymitis [5] :

  • Gram or methylene blue or gentian violet stain of urethral secretions demonstrating ≥2 white blood cells (WBC) per oil immersion field.
  • Positive leukocyte esterase test on first-void urine.
  • Microscopic examination of sediment from a spun first-void urine demonstrating ≥10 WBC per high-power field.
