RSV Antigen Rapid Test – EZER™ Diagnostic Kit

What is in the RSV Rapid Test?

The EZER™ RSV Antigen Rapid Test kit contains everything needed for 20 tests:

• 20 test cassettes

• 20 sterilized swabs

• 20 extraction tubes with nozzle caps

• 1 package insert with full instructions

Each cassette is sealed and individually packaged. Storage conditions are 2–30°C with no need for refrigeration. The test uses a simple drop-and-read format and shows clear red lines for result interpretation.

It is designed for professional use and complies with in vitro diagnostic regulations, providing fast detection of RSV-positive specimens at the point of care.

Role of RSV in Disease

Respiratory Syncytial Virus (RSV) is a single-stranded RNA virus that causes acute respiratory infections. It is one of the leading causes of hospitalization in infants and is especially dangerous in:

• Premature babies

• Elderly adults

• Patients with cardiac or pulmonary conditions

• Immunocompromised individuals

RSV can lead to bronchiolitis, pneumonia, and in some cases, acute respiratory distress syndrome (ARDS). The virus spreads rapidly via droplets and direct contact, with outbreaks often occurring in seasonal waves.

Early RSV-targeted testing allows clinicians to initiate appropriate care, implement isolation protocols, and reduce further spread-especially in neonatal wards, ICUs, and geriatric care.

About the EZER™ RSV Antigen Rapid Test

Developed by Genesis Biotech, this test delivers exceptional performance across all major specimen types. Validated against immunofluorescence standards:

• Nasopharyngeal swabs:

  • Sensitivity: 97.35%

  • Specificity: 98.15%

• Nasal aspirates:

  • Sensitivity: 96.19%

  • Specificity: 98.47%

• Throat swabs:

  • Sensitivity: 97.92%

  • Specificity: 99.09%

Overall Percent Agreement exceeds 97.5% across the board.

The test uses monoclonal antibodies to detect the RSV F protein and recognizes both RSV A and B strains. No cross-reactivity was observed with influenza A/B, parainfluenza, mumps, rotavirus, chlamydia, E. coli, S. aureus, or other respiratory flora.

This ensures that only RSV-positive samples trigger a positive result, improving diagnostic certainty.

Principle and Workflow

This is a lateral flow immunoassay built on three key components:

1. Sample pad

2. Reagent pad (with gold-conjugated antibodies)

3. Reaction membrane with capture antibodies

Testing Procedure:

1. Collect NP, nasal aspirate, or throat swab sample

2. Extract specimen into buffer tube (included)

3. Apply 3 drops of the solution into the cassette’s sample well

4. Wait 15 minutes

5. Interpret results:

   • Positive: Red lines at both control (C) and test (T) positions

   • Negative: Line only at C

   • Invalid: No control line, repeat test

The test must be read at the 15-minute mark for accurate results. Faint lines at T should still be interpreted as RSV-positive.

Clinical Application

The EZER™ RSV Rapid Test is ideal for:

• Hospitals screening patients in respiratory distress

• Pediatric clinics diagnosing early-stage bronchiolitis

• Elderly care facilities monitoring outbreaks

• Public health labs and field units during RSV season

Its speed, reliability, and ease-of-use make it indispensable during RSV outbreaks where rapid triage is needed. Particularly in ICUs and emergency departments, this test enables quick differentiation from other respiratory infections, guiding antiviral administration and infection control measures.

With validated high performance, minimal cross-reactivity, and broad sample compatibility, it is a top-tier choice for respiratory diagnostics.
