Advanced Molecular Detection for Multiple Respiratory Pathogens

QUAD RPP

A Multiplex Respiratory Pathogen Panel for COVID, Flu, and RSV

Multiple Respiratory Viruses. One Swab. One Clear Answer.

Fever, cough, body aches, fatigue. COVID-19, influenza, and RSV present so similarly that clinical judgment alone cannot reliably separate them — and yet the management diverges sharply depending on which one it is. Antiviral choice, isolation guidance, and how worried to be about a frail patient all hinge on an answer that a physical exam cannot provide. Our respiratory pathogen panel detects these major respiratory viruses from a single nasal swab by PCR and returns results expeditiously.

Key Benefits:

Expedited Results: Results typically in 24-48 hours from receipt of sample

Comprehensive Test: Detects the major respiratory viruses from a single swab

Guides Antiviral Therapy: Influenza and SARS-CoV-2 have different antivirals and different treatment windows

Supports Infection Control: Accurate identification informs isolation decisions, especially in congregate and high-risk settings

Accessible: Available to all healthcare providers, not just specialists

Understanding Respiratory Infections: A Critical Diagnostic Challenge

Distinguishing Similar Symptoms for Precise Treatment

Respiratory infections present with heavily overlapping symptoms, which makes accurate diagnosis both difficult and consequential. These viruses spread primarily through respiratory droplets released when an infected person coughs, sneezes, or talks, with COVID-19 carrying an additional potential for aerosol transmission in poorly ventilated spaces.

The management, however, does not overlap. Influenza has a narrow antiviral treatment window that closes within roughly 48 hours of symptom onset. SARS-CoV-2 has its own antivirals with their own eligibility criteria. RSV in an infant or an elderly patient carries a different risk profile again. Guessing wrong does not just mean an ineffective prescription — it means a missed window.

Early, accurate identification guides appropriate antiviral therapy and supports timely isolation to prevent onward transmission. That matters most for high-risk patients and during peak respiratory season, when these viruses circulate simultaneously and the clinical picture is at its most ambiguous.

Common Clinical Presentations:

Fever and respiratory symptoms

Cough and shortness of breath

Body aches and fatigue

Variable severity across different populations — mild in one patient, dangerous in the next

PCR vs. Antigen and Traditional Methods

Embracing Modern Diagnostics for Superior Results

PCR Testing

  • Detects the major respiratory viruses simultaneously from one swab
  • Provides expedited results
  • Superior sensitivity — detects low viral loads that antigen tests miss
  • Requires only a single sample for comprehensive testing
  • Reliably identifies early and asymptomatic infection

Rapid Antigen & Traditional Methods

  • Typically tests for one pathogen at a time
  • Antigen tests are fast but substantially less sensitive
  • Miss low-level and early-stage infection, especially before symptom peak
  • A negative antigen result frequently requires confirmatory testing anyway
  • Poor performance in asymptomatic screening

Our PCR-Based Respiratory Test

Multiplexed Detection for Complete Analysis

Our multiplex PCR test detects the major respiratory viruses — SARS-CoV-2 (COVID-19), Influenza A, Influenza B, and RSV — using multiple gene targets per virus for reliability and resilience against emerging variants. A built-in internal process control confirms the swab collected an adequate sample.

  • Specimen Type: Nasal swab in viral transport medium
  • Turnaround Time: Results typically in 24-48 hours from receipt of sample

Who Should Order the Respiratory Test

When Identifying the Virus Changes What You Do Next

Primary Care. Respiratory complaints dominate the schedule from October through March. One swab resolves the likely possibilities.

Urgent Care. High volume, high ambiguity, and patients who will not return for a second visit. A speedy accurate answer is worth more than a fast answer that might be wrong.

Pediatrics. RSV is a materially different clinical proposition in an infant than influenza is. Telling them apart changes what happens next.

Long-Term Care and Congregate Settings. Where a single missed case becomes an outbreak, accurate identification drives isolation decisions that protect an entire population.
