PURPOSE: To compare the sensitivity, specificity, and accuracy of the RPS Adeno Detector (Rapid Pathogen Screening Inc., South Williamsport, PA) against both viral cell culture with confirmatory immunofluorescence staining (CC-IFA) and the polymerase chain reaction (PCR) for diagnosing adenoviral conjunctivitis. DESIGN: Prospective, nonrandomized, masked, multicenter clinical trial. PARTICIPANTS: One hundred eighty-six consecutive patients from 5 clinical centers seeking treatment within 1 week of developing a red eye and thought to have acute conjunctivitis. METHODS: The RPS Adeno Detector is a 10-minute in-office lateral flow immunoassay. Patients were tested with the RPS Adeno Detector, CC-IFA, and PCR to detect the presence of adenovirus. MAIN OUTCOME MEASURES: The sensitivity, specificity, and accuracy of the RPS Adeno Detector were assessed for identifying cases of adenoviral conjunctivitis. RESULTS: Compared with CC-IFA, the RPS Adeno Detector was 88% sensitive and 91% specific at detecting adenoviral conjunctivitis. Using PCR as a reference method, the sensitivity of the RPS Adeno Detector increased to 89% and the specificity increased to 94%. Compared with PCR, CC-IFA was found to be 91% as sensitive and 100% as specific. CONCLUSIONS: The RPS Adeno Detector demonstrated sufficient sensitivity and specificity to be used in the physician's office for the detection of adenoviral conjunctivitis.
