What Is a Vaginal Wet Prep Used For?

A vaginal wet prep is typically used to diagnose conditions like bacterial vaginosis, yeast infections, or trichomoniasis. It can also help monitor vaginal health during treatments or after medical procedures.

How Is the Sample Collected?

A healthcare provider will collect the sample by gently swabbing the inside of your vagina. The swab is then placed in a special solution to preserve the cells and bacteria for microscopic examination.

What Does the Microscopic Examination Involve?

Under a microscope, your healthcare provider will look for different types of cells, such as epithelial cells, white blood cells, and bacteria. They may also check for signs of inflammation, abnormal cells, or fungal growth.

What Are Common Findings?

Common findings include the presence of white blood cells (which may indicate infection), yeast or fungal organisms, or an overgrowth of bacteria. The results help determine if an infection is present or if other health concerns need attention.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Vaginal wet prep results are critical for diagnosing and managing vaginal infections, monitoring chronic conditions, and ensuring proper treatment. Early detection can prevent complications and guide appropriate medical care.
