Using LGV testing technology not commercially available (LGV genotyping), CDC has assisted state and local health departments in identifying patients with LGV in cities across the United States. The majority of patients with LGV proctitis in the U.S. have been HIV-infected MSM. In states that lack laboratory capacity to perform LGV diagnostic testing, specimens may be submitted to CDC's Chlamydia Laboratory for testing. If you are a clinician with patients with symptoms consistent with LGV [mucoid/purulent anal discharge, rectal bleeding, constipation, inguinal/femoral lymphadenopathy (buboes), genital or rectal ulcer or papule, anal spasms, and/or tenesmus], please contact your state or local health departments. If state or local testing for LGV proctitis is unavailable, the state public health laboratory may forward specimens to CDC for testing.
At CDC, specimens will be tested for C. trachomatis and, if positive, will be genotyped for the identification of LGV. Serology will only be performed in conjunction with specimens tested directly for LGV (e.g. rectal swabs).
If you have patients you suspect of having LGV, or have questions about LGV, please contact both your state and local health departments. Thank you in advance for your efforts to assist in the prompt identification and control of LGV in the United States.
