Cervicitis laboratory findings

Introduction

Overview

Overview

Diagnosis of cervicitis is mostly clinical however, a finding of >10 WBC in vaginal fluid, in the absence of trichomoniasis, may indicate endocervical inflammation caused specifically by C. trachomatis or N. gonorrhea although culture is more accurate for gonococcal cervicitis.[1] The use of nucleic acid amplification tests is very helpful for the diagnosis of trichomoniasis.[2] Wet mount microscopy and direct visualisation have low sensitivity in detecting N. gonorrhea and T. vaginalis, because of this symptomatic women with cervicitis and negative microscopy should receive further testing (i.e., culture or other FDA-cleared method). Although HSV-2 infection has been associated with cervicitis, the utility of specific testing (i.e., culture or serologic testing) for HSV-2 is unknown. DNA amplification techniques has good sensitivity, but are not yet approved for diagnostic purposes of Trichomoniasis.[3] Microscopy (wet prep) and vaginal pH are useful for identifying bacterial vaginosis which may show clue cells.[4]

Laboratory Findings

Laboratory Findings

Diagnosis of cervicitis is mostly clinical however, some laboratory findings consistent with cervicitis include :

  • The use of nucleic acid amplification tests for the diagnosis of trichomoniasis.[2]
  • Wet mount microscopy and direct visualisation have low sensitivity in detecting N. gonorrhea and T. vaginalis, because of this symptomatic women with cervicitis and negative microscopy should receive further testing (i.e., culture or other FDA-cleared method).
  • Although HSV-2 infection has been associated with cervicitis, the utility of specific testing (i.e., culture or serologic testing) for HSV-2 is unknown.
  • DNA amplification techniques has good sensitivity, but are not yet approved for diagnostic purposes of Trichomoniasis[3]
  • Microscopy (wet prep) and vaginal pH are useful for identifying bacterial vaginosis which may show clue cells.[4]
