Currently, health care providers use a number of tests for
endometriosis. Sometimes, they will use imaging tests to produce a "picture" of the inside of the body, which allows them to locate larger
endometriosis areas, such as nodules or cysts. The two most common imaging tests are ultrasound, a machine that uses sound waves to make the picture, and magnetic resonance imaging (MRI), a machine that uses magnets and radio waves to make the picture.
The only way to know for sure that you have the condition is by having surgery. The most common type of surgery is called laparoscopy. In this procedure, the surgeon inflates the abdomen slightly with a harmless gas. After making a small cut in the abdomen, the surgeon uses a small viewing instrument with a light, called a laparoscope, to look at the reproductive organs, intestines, and other surfaces to see if there is any endometriosis. He or she can make a diagnosis based on the characteristic appearance of endometriosis. This diagnosis can then be confirmed by doing a biopsy, which involves taking a small tissue sample and studying it under a microscope.
Your health care provider will only do a laparoscopy after learning your full medical history and giving you a complete physical and pelvic exam. This information, in addition to the results of an ultrasound or MRI, will help you and your health care provider make more informed decisions about treatment.
