Working to reduce the spread of gonorrhea through the development of a rapid and accurate point-of-care test
A Growing Public Health Need
With the number of cases on the rise and the emergence of antibiotic resistant strains on the horizon1, diagnosing and treating gonorrhea is an increasingly critical public health need. The challenge for healthcare professionals is identifying infected women, given that ~80% of cases are asymptomatic, compared to only 10-15% of asymptomatic cases in men.2 Despite the lack of immediate symptoms, if left untreated in women, gonorrhea can lead to painful pelvic inflammatory disease and infertility.
The Benefits of a Rapid Gonorrhea Test
One of the biggest challenges with treating gonorrhea is delivering timely results, preferably at the visit when the test is given. Several studies have shown that 20% or more of patients with positive STI tests fail to return for treatment3, which may in part be explained by the lack of immediate symptoms in women and the stigma associated with STIs as well as difficulties obtaining time off from work and finding transportation to the healthcare facility. These missed treatment opportunities most likely lead to additional disease transmission.
Delivering results during a patient visit has been problematic. Nucleic acid amplification tests (NAAT) are the current gold standard, but most NAATs for gonorrhea must be performed in a central lab, requiring patients to return to their health care provider for treatment should the results be positive. Diagnostic tests that could be performed at the point of care and provide results within minutes could help ensure more patients with gonorrhea receive treatment, potentially interrupting the transmission cycle.
“If an infected patient receives timely treatment at an initial visit, further transmission can be interrupted.”
