Intended Use
The ProAdeno™+ Assay is a multiplex Real Time PCR in vitro diagnostic test for the qualitative detection of human Adenovirus (HAdV) DNA isolated and purified from nasopharyngeal (NP) swab specimens obtained from individuals exhibiting signs and symptoms of acute respiratory infection. This test is intended for use to aid in the diagnosis of HAdV infections in humans in conjunction with other clinical and laboratory findings. The test detects, but does not differentiate, serotypes 1-51. Negative results do not preclude HAdV infection and should not be used as the sole basis for treatment or other patient management decisions.
Device Description
The ProAdeno+ Assay enables detection of human adenovirus and an Universal Internal Control. An overview of the procedure is as follows: 1. Collect nasopharyngeal swab specimens from symptomatic patients using a polyester, rayon or nylon tipped swab and place into viral transport medium. 2. Add Universal Internal Control (UIC) to every sample to monitor for inhibitors present in the specimens. 3. Perform isolation and purification of nucleic acids using a MagNA Pure LC System (Roche) and the MagNA Pure Total Nucleic Acid Isolation Kit (Roche) or a NucliSENS® easyMAG™ System (bioMérieux) and the Automated Magnetic Extraction Reagents (bioMérieux). 4. Add purified nucleic acids to ProAdeno+ Supermix included in the ProAdeno+ Assay Kit. The ProAdeno+ Mix contains oligonucleotide primers, target-specific oligonucleotide probes, and a Taq DNA polymerase. The primers are complementary to a highly conserved region of human adenovirus. The probes are dual-labeled with a reporter dye attached to the 5'-end and a quencher dye attached to the 3'-end (see table below). 5. Perform amplification of DNA in a Cepheid SmartCycler® II instrument. In this process, the probe anneals specifically to the template followed by primer extension and amplification. The ProAdeno+ Assay is based on Tagman reagent chemistry, which utilizes the 5' - 3' exonuclease activity of the Taq polymerase to cleave the probe thus separating the reporter dye from the quencher. This generates an increase in fluorescent signal upon excitation from a light source. With each cycle, additional reporter dye molecules are cleaved from their respective probes, further increasing fluorescent signal. The amount of fluorescence at any given cycle is dependent on the amount of amplification products present at that time. Fluorescent intensity is monitored during each PCR cycle by the real-time instrument.

Reproducibility

The reproducibility of the ProAdeno+ Assay was evaluated at 3 laboratory sites. Reproducibility was assessed using a panel of 12 simulated clinical samples that included two adenovirus serotypes at medium and low positive levels (near the assay limit of detection, > 95% positive) and two high negative samples (high negative-1 at 0.1xLoD; high negative-2 at 0.001xLoD). Panels and controls were tested at each site by 2 operators for 5 days (12 samples and 3 controls X 2 operators X 5 days X 3 sites = 450). The overall percent agreement for the ProAdeno+ Assay was 99.2%.
