DISCOURAGED

Comment

Antigen testing for Neisseria gonorrhoeae has fallen out of favor and has little place in modern practice given the fact that better tests exist.

Part Description

LP14316-1   Neisseria gonorrhoeae
Neisseria gonorrhoeae are gram-negative cocci usually seen in pairs with the adjacent sides flattened. Pili, filament-like appendages, extend from the cell surface and have a role in adherence. Gonorrhea is usually acquired by sexual contact. Men and women aged 15-29 have the highest incidence of gonorrhea. Number of sexual partners, sexual practices and preference, condom use and population mobility contribute to disease incidence. The most frequent sites are the cervix, urethra, rectum, pharynx and conjunctiva. The most common symptom in men is discharge that may be scanty and clear or cloudy to copious and purulent, and often dysuria. Asymptomatic men are an important reservoir for transmission. Endocervical infection is the most common form of infection in women. Ocular infections occur most commonly in newborns who are exposed in the birth canal and can lead to corneal scarring or perforation. Gonococcal bacteremia may lead to disseminated infection including pelvic inflammatory disease in as many as 15 percent of women, leading to an increased probability of infertility and ectopic pregnancy. While antibiotics have successfully treated gonorrhea for decades, N. gonorrhoeae has developed antimicrobial resistance to every drug used for treatment. The Centers for Disease Control and Prevention recommends combination therapy using two antimicrobials with different mechanisms of action (e.g., a cephalosporin plus azithromycin) to improve treatment efficacy and potentially slow the spread of resistance to cephalosporins.

Change Reason

The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
