Rapid Turnaround Test
Patients randomized to this arm will be tested for a sexually transmitted infection (STI) with both the rapid nucleic acid amplification test (NAAT) as well as the conventional polymerase chain reaction (PCR) test. The results from the rapid turnaround test will guide providers on treatment decisions for a possible STI. The results from the PCR test will be used to verify the results of the rapid turnaround test. Cepheid Xpert CT/NG Rapid Turnaround Test: This diagnostic test will be used to help clinicians determine the need for antibiotic prescriptions in patients with a suspected sexually tract infection. Polymerase chain reaction (PCR): This is the standard of care for diagnosis of a suspected sexually transmitted infection.
Usual Care
Patients randomized to this arm will be tested for a sexually transmitted infection (STI) using the conventional PCR test. The results from the PCR test normally take approximately 48-72 hours and these patients will likely receive treatment based on the decision of the clinical provider. The results from the PCR test will be used to verify the decision of the clinical provider to treat or withhold treatment for a possible STI. Polymerase chain reaction (PCR): This is the standard of care for diagnosis of a suspected sexually transmitted infection.
