How to correctly diagnose whether you have cervical warts

Cervical warts are a common sexually transmitted disease in modern society. In our country, sexually transmitted diseases are very shameful. It will make people think that you are a person with a chaotic sex life. Regardless of young or old, they all avoid this disease. When you find some symptoms of cervical warts, you will inevitably be frightened. At this time, it is particularly important to know how to check the cervical warts virus. The following will introduce to you how to correctly diagnose whether you have cervical warts.

1. Acetic acid whitening test

Applying 3-5% acetic acid solution topically or compressing for 5-10 minutes can cause the HPV-infected area to turn white, the so-called "acetic acid whitening phenomenon". However, the specificity is not high, and some chronic inflammations, such as candidal vulvitis, genital trauma and non-specific inflammation, can all cause false positives.

2. Cytological examination

Using vaginal or cervical wart tissue smears and Papanicolaou staining, two types of cells can be seen, namely vacuolated cells and dyskeratotic cells, which are of diagnostic value for cervical warts.

3. Histopathological examination

The presence of vacuolated cells above the spinous layer and in the granular layer is important evidence for diagnosing HPV infection.

4. Immunological tests

Antibodies against HPV proteins are used to detect HPV antigens in diseased tissues. This method is not very sensitive, with a detection rate of only about 50%.

5. Nucleic acid hybridization test

It is an important means of detecting HPV infection, including dot blot, tissue in situ hybridization, and nucleic acid imprint (Southern blot). These methods have high specificity and sensitivity and are sensitive and reliable methods for diagnosing HPV infection. However, the technical operation is cumbersome and has not been widely used in clinical practice.

6. Polymerase chain reaction (PCR)

It is currently the most sensitive method for detecting HPV infection, and can also perform type-specific analysis. It has the characteristics of high sensitivity, simplicity and rapidity. It has been widely used in clinical practice.
