Chlamydia and gonorrhea are two of the most common sexually transmitted diseases in the United States, infecting approximately three to five million Americans annually. Unfortunately, there are often no symptoms and, if left untreated, these infections may lead to severe complications. Many professional organizations, such as the American College of Obstetricians and Gynecologists (ACOG), recommend that the following patient populations be screened for chlamydia and gonorrhea:

• All patients under the age of 25 (annual screening)
• All other patients who are considered high risk
• History of multiple sexual partners or a sexual partner with multiple contacts
• Sexual contact with persons with culture-proven STDs
• History of repeated episodes of STDs
• Attendance at clinics for STDs
