Cytomegalovirus (CMV) DNA Genital Specimen Probe (Qualitative)
This test detects the presence of cytomegalovirus (CMV) genetic material in genital samples, such as swabs, to help diagnose infections or monitor conditions related to CMV.

Your doctor may order this test if you have symptoms that suggest an infection or condition this test can detect, if a previous result needs to be confirmed, or as part of routine screening. It may also be used to monitor a known condition or to check whether a current treatment is working as expected.
Your healthcare provider may recommend this test if you have symptoms like genital sores, unusual discharge, or if you’re at higher risk for CMV infection (e.g., during pregnancy, after organ transplant, or with weakened immune systems). It can also be used to confirm a suspected CMV infection in genital areas.
A trained healthcare professional will collect the sample using a sterile swab or another suitable container while following standard safety procedures. In most cases, no special preparation is needed, but you should tell the staff about any antibiotics or topical products you have used recently, since these can sometimes affect the result.
A sterile swab is collected from the genital area (e.g., vagina, penis, or anus) to gather cells and fluids. The sample is then sent to a lab for testing. No special preparation is needed, but avoid bathing or using vaginal products 24 hours before the test.
After collection, the sample is sent to a laboratory, where technicians look for the organism, antigen, or genetic material associated with the condition being tested. Depending on the method used, detection may rely on a culture, an immunoassay, or a molecular technique such as nucleic acid amplification, which can identify even very small amounts of the target.
The lab uses a molecular probe to detect CMV DNA fragments in the sample. If CMV DNA is present, the test will indicate a positive result. This method is highly sensitive for detecting early or low-level infections.
A positive result generally means the targeted organism or marker was found in your sample, while a negative result suggests it was not detected at the time of testing. Your healthcare provider will interpret the result alongside your symptoms, medical history, and other findings, because no single test tells the whole story. If the result is unclear, repeat testing may be recommended.
A positive result means CMV genetic material was found in the sample, suggesting an active infection. A negative result means no detectable CMV DNA was found at the time of testing. Results alone do not confirm the cause of symptoms; they are used alongside clinical findings and other tests.

Frequently asked questions
This test is critical for diagnosing genital CMV infections, which can cause symptoms like pain, swelling, or discharge. In high-risk groups (e.g., pregnant women, transplant patients), it helps guide treatment to prevent complications or spread of infection.
A positive result indicates the presence of CMV DNA in your genital sample, which strongly suggests an active CMV infection. Your healthcare provider will work with you to determine the best course of action, which may include antiviral treatment or monitoring.
This test is specifically designed for genital samples. If you need testing for CMV in other areas (e.g., blood, urine), a different test or sample type would be used.
