Respiratory

Point-of-care rapid testing for respiratory. OEM/ODM manufacturer.

Overview

COVID-19, influenza and RSV are the major seasonal respiratory viruses. Rapid antigen tests support syndromic diagnosis and triage.

Clinical Context

COVID-19 (SARS-CoV-2), influenza A/B and RSV are the major seasonal respiratory viruses with overlapping symptoms.

Diagnostic Markers & Methods

Antigen tests (SARS-CoV-2, Influenza A/B, RSV) · multiplex combo devices · RT-PCR for confirmation.

Antigen vs Antibody

Antigen tests detect viral proteins (active infection); antibody tests are not used for acute respiratory diagnosis.

Diagnostic Workflow

Syndromic presentation → multiplex antigen test (COVID/Flu/RSV) → PCR confirmation where needed → isolation/treatment decisions.

Testing Window

Antigen best in the early symptomatic phase (first few days of symptoms).

Interpretation

Antigen tests are fast but less sensitive than molecular; a negative result during high prevalence does not exclude infection.

False Negative / Positive Considerations

False negative: low viral load or late sampling. False positive: rare; confirm clinically or by PCR if discordant.

Confirmatory Testing

RT-PCR for respiratory viruses.

Testing Settings

Multiplex antigen tests suit clinics and emergency departments; PCR is the lab reference.

Sources

WHO COVID-19 guidance; CDC influenza & RSV.

Progene's Take

Position: Sell the multiplex COVID/Flu/RSV combo, not single-target antigen tests — winter syndromic demand makes the combo the higher-margin, higher-utility SKU.

Three viruses present identically; a combo resolves the differential in one test.
Antigen tests are fast but less sensitive — set buyer expectations and offer PCR confirmation.
Seasonal demand means inventory planning, not just product choice.

This is the buyer-advisor view of the technical team — editorial guidance, not a substitute for product IFU or local regulatory requirements.

Frequently Asked Questions

How accurate are rapid flu/COVID/RSV antigen tests?

Antigen tests are fast but less sensitive than molecular (PCR). A negative result during high prevalence does not exclude infection — confirm clinically or by PCR.
