A doctor may perform the following tests to determine the cause of the amenorrhea:
Blood tests may be performed to determine the levels of hormones secreted by the pituitary gland (FSH, LH, TSH, and prolactin) and the ovaries (estrogen).
Ultrasonography of the pelvis may be performed to assess the abnormalities of the genital tract or to look for polycystic ovaries.
CT scan or MRI of the head may be performed to exclude pituitary and hypothalamic causes of amenorrhea.
If the above tests are inconclusive, additional tests may be performed including:
Thyroid function tests
Determination of prolactin levels
Hysterosalpingogram (X-ray test) or saline infusion sonography (SIS), both of which examine the uterus
Hysteroscopy (visual inspection of the uterine cavity)
