Overview
Laboratory Findings
Urethritis is considered on the basis of any of the following:
- 1- Mucoid, mucopurulent, or purulent discharge on examination.
- 2- Gram stain of urethral secretions demonstrating ≥2 WBC per field
- 3- Positive leukocyte esterase test on first-void urine or microscopic examination of sediment from a spun first-void urine demonstrating ≥10 WBC per high power field.
Gram Stain
- The presence of PMNs without any visible organisms is consistent with nongonococcal urethritis.
- Presumed gonococcal infection is established by documenting the presence of WBC containing intracellular purple diplococci in gram stain.
