Test Details


Use

This test detects influenza A / H5 subtype by nucleic acid amplification.
 


Limitations

This test detects sequences for influenza A and the H5 subtype. Influenza A/H5 is currently very rarely found in humans in the United States. Results from this test must be correlated with the clinical history, epidemiological data and other data available to the clinician evaluating the patient. Viral and bacterial nucleic acids may persist in vivo independent of organism viability. Detection of organism target(s) does not imply that the corresponding organisms are infectious or are the causative agents for clinical symptoms. The detection of viral and bacterial nucleic acid is dependent upon proper specimen collection, handling, transportation, storage and preparation. Failure to observe proper procedures in any one of these steps can lead to incorrect results. There is a risk of false positive or false negative values resulting from improperly collected, transported or handled specimens. 

This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
