Advanced Diagnostic Laboratories

COVID-19 PCR-Based Testing

National Jewish Health Advanced Diagnostic Laboratories is now accepting COVD-19 samples to confirm the presence of the SARS-CoV-2 virus genetic material.

About Our COVID-19 Test

National Jewish Health Advanced Diagnostic Laboratories uses two PCR-based methodologies to process samples: (1) SARS-CoV-2 real-time RT-PCR and (2) SARS-CoV-2 RT-PCR by MassArray. The first assay is based on the ThermoFisher TaqPath™ COVID-19 Combo Kit. The second assay is a novel test that National Jewish Health developed in collaboration with Agena Biosciences.

These PCR-based tests are intended for the qualitative detection of nucleic acid from SARS-CoV-2 in upper and lower respiratory specimens such as nasopharyngeal, midturbinate, nasal and oropharyngeal specimens and bronchoalveolar lavage samples collected from individuals suspected of COVID-19.

Turnaround time is 24-48 hours.
