Premenstrual Syndrome (PMS)
Exams and Tests
No single test can diagnose PMS. A diagnosis of PMS or Reference premenstrual dysphoric disorder (PMDD) Opens New Window is usually based on a Reference medical history and information from a two- or three-cycle menstrual diary (What is a Reference PDF Opens New Window document?) where you record your symptoms, menstruation days, and ovulation days, if possible.
Treatable thyroid problems sometimes cause symptoms like those of PMS. So you may have a Reference thyroid-stimulating hormone (TSH) blood test to make sure that your thyroid gland is working properly.
It's important for your doctor to rule out other conditions that cause symptoms like those of PMS, so it may take more than one visit to diagnose your symptoms. Diagnosing PMS may be difficult if you have another condition that gets worse during the last 2 weeks of your menstrual cycle.
