To confirm a diagnosis of gonorrhea, your doctor takes samples for laboratory analysis of any discharge noted during a physical exam. Your doctor may also test you for other STDs, such as chlamydia, syphilis and human immunodeficiency virus (HIV), the virus that causes AIDS. Other STDs commonly occur along with gonorrhea.

Prevention
To prevent the spread of gonorrhea, use latex condoms and avoid oral sex. Gonorrhea is highly contagious, and yet may cause no signs or symptoms.
If you have gonorrhea, avoid sexual contact until a course of antibiotics completely eliminates your infection. Having had gonorrhea once doesn't provide you immunity from getting it again. Consider alerting your sexual partner or partners so that they may be tested for the infection, as well, and help prevent further spread of the disease. Your state health department can work with you to accomplish this.
Schedule a follow-up examination with your doctor after you've completed the course of antibiotics. Your doctor can check to see if your infection has been completely eliminated.
