A gram stain/wet smear of the high vaginal swab (HVS) is a laboratory test performed to identify bacterial or fungal infections of the female reproductive tract. This test helps in the diagnosis of bacterial vaginosis, candidiasis, and other vaginal infections.
When this test is required
The test is requested when a person presents with symptoms of vaginal infection or when a healthcare provider suspects the presence of a vaginal infection during a routine gynecological exam.
What the Test Detects
This test is used to identify the presence of bacteria or yeast in the vaginal secretions. The gram stain helps identify the type of bacteria present, while the wet mount can reveal the presence of yeast, trichomonas, or clue cells.
Preparation for the Test
No specific preparation is needed for this test.
Sample Requirements
A high vaginal swab (HVS) is collected by inserting a sterile swab into the vagina and rotating it to obtain a sample of secretions from the cervix and vaginal walls.
Additional Notes
It is important to note that a negative test result does not rule out the presence of a vaginal infection. Further testing or clinical evaluation may be necessary if symptoms persist or if the healthcare provider suspects a different underlying condition.
