Understanding Lab Tests for Lymphogranuloma Venereum
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Lymphogranuloma venereum (LGV) is a chronic sexually transmitted infection caused by specific strains of Chlamydia trachomatis bacteria. This condition primarily affects the lymphatic system and requires specialized testing for accurate diagnosis and appropriate antibiotic treatment.
Recommended Test
Chlamydia and Gonorrhea Test
This test is fundamental for diagnosing lymphogranuloma venereum as it detects Chlamydia trachomatis, the specific bacterium responsible for this chronic infection of the lymphatic system. The test can identify the presence of chlamydial DNA or antigens, confirming the underlying bacterial cause of LGV symptoms.

What is Lymphogranuloma Venereum?
LGV is caused by three specific serovars (L1, L2, and L3) of Chlamydia trachomatis, which are different from the strains that cause typical genital chlamydial infections. The infection progresses through three stages, beginning with small genital lesions and potentially leading to chronic inflammation of lymph nodes and surrounding tissues if left untreated.
Diagnosing Lymphogranuloma Venereum
Because LGV symptoms can mimic other conditions and may not appear immediately after infection, laboratory testing is essential for definitive diagnosis. Early detection through testing allows for prompt treatment with appropriate antibiotics, preventing the progression to more serious complications.
Why Testing is Critical
LGV requires different treatment duration and monitoring compared to uncomplicated chlamydial infections. Without proper diagnosis through testing, the infection can progress to cause permanent damage to lymph nodes, genital tissue, and surrounding structures. Testing also helps prevent transmission to sexual partners.
