Gonorrhea (colloquially known as the clap) is a common human sexually transmitted infection caused by the bacterium Neisseria gonorrhoeae. This infection is transmitted through vaginal, oral, or anal sex. The usual symptoms in men are burning with urination and penile discharge. Women, on the other hand, are asymptomatic half the time or have vaginal discharge and pelvic pain. If untreated, it may cause pelvic inflammatory disease or affect joints and heart valves. Positive tests for gonorrhea should be followed by tests for other sexually transmitted diseases such as chlamydia, syphilis and human immunodeficiency virus.
First catch morning urine is the preferred sample for analysis. If this is not possible it is advisable not to urinate at least two hours before sample collection.
