An agent used to identify diseased tissue in the cervix is?

Lugol's solution is often used in gynecological procedures to identify diseased tissue in the cervix, particularly during cervical examinations. This solution contains iodine and is effective in staining abnormal cells, allowing for easier visualization of any lesions or precancerous changes on the cervix. When applied, it selectively colors normal tissue brown while diseased areas, which may not absorb the iodine as effectively, remain unstained or appear lighter. This contrast aids healthcare providers in identifying areas that may require further investigation or intervention, such as biopsies.

In contrast, methylene blue is more commonly used as a dye in surgical procedures but does not specifically target diseased cervical tissue in the same way. Tannic acid is not typically used for identifying cervical disease; rather, it has application in tissue fixation or hemostasis in other settings. Conization refers to a surgical procedure for removing a cone-shaped section of the cervix for diagnostic and therapeutic purposes, not a staining agent used for identifying diseased tissue.
