Vaginal Wet Prep for Microscopic Examination (Smear)

What Is a Vaginal Wet Prep Test?

A healthcare provider collects a sample of vaginal fluid using a sterile swab. The sample is placed on a microscope slide and prepared with a wet mount (a drop of fluid) to observe cells and microorganisms under magnification. This method helps detect cellular changes, yeast, bacteria, or other pathogens that may indicate infections or other conditions.

Why Might You Need This Test?

This test may be recommended if you have symptoms like unusual discharge, itching, burning, or vaginal irritation, or if your healthcare provider suspects an infection (e.g., bacterial vaginosis, yeast infection, or trichomoniasis). It can also be part of routine pelvic exams or preconception evaluations.

What Happens During the Test?

You’ll likely sit comfortably while a healthcare provider gently collects a sample from your vagina using a sterile swab. The sample is then processed and observed under a microscope to identify any abnormal cells, microorganisms, or inflammatory signs.

Preparation and Care After the Test

No special preparation is needed before the test. Avoid douching, sexual activity, or using vaginal products 24 hours before the test. Afterward, avoid inserting anything into your vagina for a few hours to allow the sample to be collected properly.
