Overview: Adenovirus PCR TestIntroduction: The Adenovirus PCR Test detects adenovirus DNA, a virus causing respiratory infections, sore throat, or conjunctivitis, to confirm infection and guide treatment. Aligned with 2023 infectious disease guidelines, it uses PCR for high sensitivity, ensuring accurate viral detection. This test is critical for guiding antiviral therapy, preventing complications, and improving outcomes in virology.
Other Names: Adenovirus PCR Assay, Adenovirus DNA Test.
FDA Status: Laboratory-developed test (LDT), meeting virology standards for diagnostic accuracy.
Historical Milestone: Adenovirus was identified in the 1950s. PCR-based detection emerged in the 1990s, and by the 2010s, real-time PCR improved diagnostic speed and specificity.
Purpose: Diagnoses adenovirus infections, guides therapy, and monitors disease in patients with respiratory or ocular symptoms.
Test Parameters: 1. Adenovirus DNA
Pretest Condition: No fasting required. Collect swab, sputum, body fluid, BAL, CSF, plasma, stool, or saliva at symptom onset. Report respiratory or ocular symptoms.
Specimen: Swab (1-2 swabs in transport medium), 5-10 mL sputum, body fluid, BAL, or stool, 1-2 mL CSF or saliva, or 2-4 mL plasma (EDTA). Transport in a biohazard bag within 24 hours.
Sample Stability at Room Temperature: 24 hours
Sample Stability at Refrigeration: 48 hours
Sample Stability at Frozen: Not frozen, as DNA may degrade.
Medical History: Document respiratory, ocular, or gastrointestinal symptoms, or recent viral exposures. Include current medications or immune status.
Consent: Written consent required, explaining the test's purpose, diagnostic implications, and potential therapy needs.
Procedural Considerations: Uses real-time PCR to detect adenovirus DNA. Results take 3-5 days due to molecular complexity.
Factors Affecting Result Accuracy: Low viral load or contamination may cause false results. Improper storage can degrade samples.
Clinical Significance: Positive results confirm adenovirus infection, prompting supportive or antiviral therapy. Negative results may require repeat testing in early infection.
Specialist Consultation: Consult an infectious disease specialist or virologist for result interpretation. Ophthalmology referral is advised for conjunctivitis.
Additional Supporting Tests: Viral culture, antigen testing, or serology to confirm adenovirus infection.
Test Limitations: False negatives may occur in early infection. Non-adenovirus infections require clinical correlation.
