Making the Diagnosis
PID can be hard to diagnose because symptoms are often unnoticed. If a doctor suspects PID after a physical exam (including an internal pelvic exam), treatment is started immediately.
Additional tests such as blood tests, a pregnancy test, tests for STIs, ultrasound, biopsy, or laparoscopy (a fiber-optic tube is inserted through the abdominal wall allowing the doctor to see the internal pelvic organs) may be performed if more information is needed.
