How is HPV tested?

Human papillomavirus is a relatively serious problem. If you are not careful, it will cause sexually transmitted diseases. Many sexually transmitted diseases are caused by this virus infection, such as genital warts, which is the most common sexually transmitted disease. Most of them only occur in male patients. After it occurs, it will cause great damage to the patient's reproductive organs, and ultimately make the patient unable to reproduce normally, thus leading to sexual disharmony between couples. Therefore, it is necessary to do a human papillomavirus test before the onset of the disease, so as to control the possibility of worsening of the disease, and also to choose the treatment method suitable for you according to the development of your disease at the first time.

The acetic acid white test can be used by applying 3-5% acetic acid to the wart for 2-5 minutes. The lesion will turn white and slightly raised. Anal lesions may take 15 minutes. The principle of this test is the result of protein coagulation and whitening with acid. The keratin produced by HPV-infected cells is different from that produced by normal uninfected epithelial cells, and only the former can be decolorized by acetic acid. The acetic acid white test has a high sensitivity in detecting HPV and is better than conventional testing in observing histological changes. However, false positives may occasionally occur in cases of epithelial thickening or traumatic abrasions, and false positive blanching signs may appear ill-defined and irregular.

Since the condyloma virus does not exist in the blood, blood tests are of little significance. There are two ways to identify whether it is genital warts: one is to go to the hospital for a live test, and the other is to use drugs to directly identify it (rare dew). If it turns white after three days, it is condyloma acuminatum, otherwise it can be ruled out. The accuracy of these two identification methods is relatively high, and the diagnosis can be made early and the right medicine can be prescribed.

Cervical precancer screening includes cervical liquid-based cytology and human papillomavirus testing. There are two types of human papillomavirus tests: high-risk and low-risk. If the high-risk type is positive, reexamination is required after treatment.

The characteristic change of cervical HPV-positive cells is the appearance of specific hollow cells. It initially appears on the surface. When the atypical hyperplasia reaches more than 2/3, the number of hollow cells decreases, and the morphology shows the characteristics of poorly differentiated squamous cell carcinoma. The most critical factor in the detection method is the detection sensitivity. Detection of HPV and DNA based on gene amplification is currently the most sensitive detection method.
