Rapid Chlamydia Testing

Developing a test that addresses the real-world challenges of reducing the spread of sexually transmitted infections (STIs)

A Pressing Public Health Challenge


Chlamydia trachomatis is the most frequently reported bacterial infection in the United States, with infection rates continuing to increase across all regions, ethnic groups, and genders.1 However, many cases are asymptomatic and undiagnosed, leading to a likely underestimate of the true disease prevalence.2 Underdiagnosis has a direct impact on women’s health, as untreated Chlamydia infection can lead to painful pelvic inflammatory disease and infertility.



Cases of Chlamydia reported in 2019 in the US1



Of these cases were in people aged 15 – 241



Of women and 40-50% of men infected with Chlamydia are asymptomatic2

A Clear Need for Rapid Chlamydia Testing


The asymptomatic nature of Chlamydia further complicates management of the disease. Nucleic acid amplification tests (NAAT) are the current gold standard, but most NAATs for Chlamydia must be performed in a central lab, requiring patients to return to their health care provider for treatment when the results are positive.3 Several studies have shown that 20% or more of patients with positive STI tests fail to return for treatment.3 The lack of immediate symptoms and the stigma associated with STIs may explain, in part, the reluctance of patients to return for a second visit. Additional barriers to return visits may be due to difficulties obtaining time off from work an/or finding transportation to the clinic.

Diagnostic tests that can be performed at the point of care and provide results within minutes could help ensure more patients with Chlamydia infections receive treatment, potentially stopping the transmission cycle.

“If an infected patient receives timely treatment at an initial visit, further transmission can be interrupted.”

-Barrow, et al.3
