Lab tests may be done. A blood test called a complete blood count (CBC) can help determine if you have anemia or an infection. A blood test called thyroid stimulating hormone can determine if you have an underactive thyroid (hypothyroidism) causing heavy menstrual bleeding. You may have tests for certain bleeding disorders. You may have a pregnancy test and tests for sexually transmitted infections (STIs).
Based on your symptoms and your age, other tests may be needed:
Ultrasound exam—Sound waves are used to make a picture of the pelvic organs.
Hysteroscopy—A thin, lighted scope is inserted through the vagina and the opening of the cervix. It allows your ob-gyn to see the inside of the uterus.
Endometrial biopsy—A sample of the endometrium is removed and looked at under a microscope.
Sonohysterography—Fluid is placed in the uterus through a thin tube while ultrasound images are made of the uterus.
Magnetic resonance imaging (MRI)—This imaging test uses powerful magnets to create images of the internal organs.
Computed tomography (CT)—This X-ray procedure shows internal organs and structures in cross section.
