The saline wet mount was prepared by combining a small amount of vaginal discharge specimen with one drop of normal saline, covered with a cover slip, and examined by light microscopy for the presence of clue cells
, trichomonads, pseudohyphae, leukocytes, and Lactobacillus sp.
2) In one study of 640 women evaluated for BV, observation of clue cells
was the most reliable diagnostic finding to predict BV.
Matching of the results of clue cells

2,6) Presence of clue cells
found in a wet mount preparation of vaginal secretions is a strong indication for BV.
are vaginal epithelial cells coated with coccobacilli giving an appearance as if coated with ground black pepper.
Likewise, any two-criteria combination involving amine odor, clue cells
, or elevated pH also had sensitivities and specificities that rivaled those of the current three-criteria requirement.
Reporting clue cells
in the urine provides one piece of information to the clinician, but is not a definitive clinical finding to diagnose a urinary tract infection or a vaginal condition.

Bacterial vaginosis was defined as the presence of clue cells
in a vaginal specimen and at least two of the following findings: a vaginal discharge, vaginal specimen pH greater than 4.

Q Are clue cells
significant when observed in a clean catch urine specimen?
A wet mount was examined by bright field microscopy at x 400 magnification for the presence of T vaginalis and clue cells
(vaginal epithelial cells studded with coccobacilli).
