Diagnosis of human papillomavirus

the diagnosis of human papillomavirus (HPV) is often sufficient to conduct examination of the patient.Diagnosis of human papillomavirus in clinical manifestations is the main type of diagnosis, because if there are no warts, treatment of warts is not assigned.But to identify the type that caused the proliferation, have to pass tests because HPV can be oncogenic risk.

PCR diagnosis of HPV

To detect HPV and determine its type, is commonly used PCR - classic DNA diagnosis of HPV.This study is assigned to those patients who have been diagnosed papilloma when viewed as important to determine not only the presence of human papilloma virus in the body, but also its type, the number of virus at the time of analysis.By determining the number of HPV may determine the nature of the process.Warts can appear as a result of simultaneous decrease in immunity, and can be a chronic process, stretching for many years.In addition, due to PCR diagnosis may identify the type of human papilloma virus that lives in the bod

y of the patient, it is necessary to determine the risk of carcinogenicity in HPV each case.

impossible to completely cure HPV, but there is an opportunity to "put down" the virus and its activity for several years.

colposcopy study HPV

Colposcopy performed when they were diagnosed with genital warts of the external genitalia and cervix.This kind of diagnosis involves the use of a colposcope, a special microscope, using which it is possible to study the appearance of the cervix.By increasing the individual papillae can be seen, each of which passes kinky blood capillaries.For an accurate diagnosis, warts treated with 3% solution of acetic acid, whereby capillaries spazmiruyutsya and warts becomes pearly white color.Before the cervix is ​​painted with acetic acid, it looks like a big pink spot.After staining, there is a clear allocation of all available pathology.When kolposkopcheskom study of HPV other than acetic acid, Lugol's solution is used, which is a solution of iodine-containing water-based.This procedure should be carried out to make it easier to discern the border of pathology, since the solution of Lugol stain healthy cells of the cervix, and pathologically altered - no.

biopsy for the diagnosis of HPV

Under biopsy meant taking tissue from the body, and their follow-up study after coloring with special dyes.A biopsy is one of the most common method for the diagnosis of HPV.In a number of cancers method is mandatory for the diagnosis of "papilloma" as before to start treatment of papillomas, to exclude the possibility of cancer.For the diagnosis of HPV using such varieties as the biopsy cytological and histological study.

cytological research is doing research under a microscope the cells with which they identify changes caused by a viral infection.Fence for cell studies carried out on the surface of the cervix.Such a study is performed in order to identify as early as possible or exclude the presence of precancerous diseases.Therefore, usually women who are infected with oncogenic HPV types, each year is assigned to conduct cytology from the cervix to promptly revealed dysplasia of the cervix.

to more accurate diagnosis, histological studies provided.For this piece of tissue sampling is carried out and executed to study the structure of cells and their correct arrangement of layers, the structural features of the fabric.A piece of fabric is dewatered using special solutions.The preparation was then embedded in paraffin.With the help of a microtome or a very sharp knife cuts are carried out.Only after this is done the various color dyes, allowing the cells and tissues of the elements become visible under the microscope.
