few months ago, I wrote about colposcopy, what it is and the instruments used, but did not mention about tests performed during this test.
First, after settling in the gynecological position and placement of a speculum, is necessary to visualize the cervix, detailing the presence (or absence) of discharge, bleeding, etc ... Subsequently carried out 3 tests that will help make the diagnosis of cervical neoplasia:
1) Solution Physiological involves the application of saline in the cervix and the subsequent viewing with a green color filter have the colposcope to determine the architecture of the blood vessels in the area. When there neoplasia, or pre-malignant lesions and malignant blood vessels are seen enlarged and irregular.
2) Test Hinselman or acetic acid: is the application of the acid in the cervix, when a lesion becomes white, so called aceto-white lesions and are suggestive of HPV infection (although this is not always the case).
3) Finally, the regulatory test Schiller with Lugol's solution: It consists of applying a solution of iodine on the cervix, resulting in a mahogany stain over the entire surface, but if you notice an area with defined borders that does not stain, it comes iodonegativas areas, and are also suggestive of neoplastic lesions. There are areas that do not stain, such as glandular tissue, which is why ectopia or ectropion (eversion gland ar), is pale, but this is normal.
seen in the image cervix with acetic acid and iodine, are clearly visible injuries.
Although it appears complicated, it is very simple, although a bit annoying, is painless. It is important that while you are doing this, I explain the results and if you have doubts solve it immediately.
