Pcr Panels

Respiratory Pathogen Testing (QPCR)

Respiratory Pathogen Panel (RPP) detects specific nucleic acid pathogens from patients exhibiting signs and symptoms of respiratory illness. RPP testing provides proper diagnosis and detection of both viral and bacterial infections with 24-hour turnaround time. Covid-19 is included on our 34-pathogen panel. Respiratory panel testing is non-invasive which helps to minimize patient’s discomfort.
The following is a list of Pathogens that can be ordered:

Viral
Coronavirus (seasonal)
Coronavirus SARS-CoV-2
Influenza A virus Influenza A virus A/H1-2009
Influenza A virus A/H3
Influenza B virus
Respiratory syncytial virus
