Tests and diagnosis

By Mayo Clinic Staff

There are no unique physical findings or laboratory tests to positively diagnose premenstrual syndrome. Your doctor may attribute a particular symptom to PMS if it's part of your predictable premenstrual pattern.

To help establish a premenstrual pattern, your doctor may have you record your signs and symptoms on a calendar or in a diary for at least two menstrual cycles. Note the day that you first notice PMS symptoms, as well as the day they disappear. Also be sure to mark the days your period starts and ends.
