Endometriosis is generally diagnosed through color ultrasound and CA-125 blood tests. If the endometrial tissue is located within the uterine muscle, it forms adenomyosis, at which point the ultrasound will show an enlarged uterus and uneven muscle wall echogenicity. Blood tests for the tumor marker CA-125, if elevated above the normal level of 35, generally indicate adenomyosis. If the endometrial tissue is located in the ovaries, it can form ovarian chocolate cysts, which are visible on the ultrasound as ovarian sections and echoes, with typical ultrasound reports indicating ovarian chocolate cysts. Therefore, routine examinations for endometriosis typically include color ultrasound and blood tests, which can confirm the diagnosis.
