Fibroids are diagnosed through a routine examination at a gynecologist's office, according to Mayo Clinic. The doctor suspects the presence of fibroids if she notices any irregularities through palpating the uterus.
Another way to diagnose fibroids is through ultrasound, says Mayo Clinic. This procedure utilizes sound waves to see into the uterus where a doctor can find and measure any fibroids. An ultrasound can be performed by moving a transducer over the uterus or inserting it into the vagina.
Other tests used to diagnose fibroids are hysterosonography, hysterosalpingography and hysteroscopy, explains Mayo Clinic. In hysterosonography, the uterus is enlarged with saline solution. This makes it easier to see the inner structures of the uterus. With a hysterosalpingography, a doctor uses a dye and X-rays to see inside the uterus and the fallopian tubes. This can also be a test to check for infertility problems. The uterus is also enlarged with saline solution during hysteroscopy, but the doctor inserts a lighted probe to check the uterine cavity and the fallopian tubes.
If the patient is experiencing abnormal bleeding, the doctor may also order lab tests to rule out more serious conditions, notes Mayo Clinic. Blood tests can also indicate whether the patient is suffering from anemia or thyroid problems.
