Overview

Vaginal discharge is a common patient complaint that is paired with anxiety regarding sexually transmitted diseases. If a STD is detected, a search for all other STDs should be done. Advise the infected patient to inform all sexual partners of their diagnosis.

Laboratory Findings

Initial tests include:

• CBC
• urinalysis
• urine culture
• beta-hCG
• gonorrhea culture
• chlamydia culture

Other Diagnostic Studies

Type	pH	Discharge	Odor	Wet Mount
Trich	>4.5	yellow-green, copious	present	motile, flagellated
BV	>4.5	white-grey	fishy	clue cells
Candida	<4.5	white, curd-like	none	pseudo-hyphae
GC		mucopurulent	varies	PMNs
A.V.		thin,gray,watery	none	few epithelial cells
