In Adenoviral conjunctivitis, the AdenoPlus test is used to detect what?

• A. Adenovirus antigen in the tear film (positive AdenoPlus)
• B. Bacterial organisms
• C. Fungal organisms
• D. No diagnostic value

Answer: (A)

This test is a rapid immunochromatographic assay that detects adenovirus antigen in the tear film. A positive result supports a diagnosis of adenoviral conjunctivitis and helps distinguish it from bacterial or fungal causes, guiding management and infection-control decisions. It does not test for bacteria or fungi, and a negative result doesn’t completely rule out adenoviral infection because the test isn’t perfect and viral antigen levels can be low at times.
