Laboratory Studies

The initial steps in evaluating a patient for premenstrual dysphoric disorder (PMDD) are aimed at excluding organic syndromes with manifestations similar to those of PMDD, such as thyroid disorders, anemia, perimenopause, and menopause. The role of laboratory studies is limited to screening for medical conditions considered in the differential diagnosis. Although some tests may be needed to reassure the patient, excessive testing can be counterproductive by making the patient more anxious.

Laboratory studies should include the following:

  • Thyroid function tests

  • Complete blood count (CBC)

  • Follicle-stimulating hormone (FSH) level
