The EZER™ HPIVs Antigen Rapid Test is a rapid immunochromatographic assay for the qualitative detection of Human Parainfluenza Virus types 1, 2, and 3 in nasopharyngeal swab and nasal aspirate specimens. It is designed to aid in the early diagnosis of HPIV infections by detecting viral nucleoprotein antigens during the acute stage of respiratory illness.
Covering HPIV-1, HPIV-2, and HPIV-3, this test addresses key viral causes of pediatric and adult respiratory infections. It can be used as an initial diagnostic tool in clinical laboratories, hospital settings, and outbreak response scenarios. Results are available within 15 minutes, enabling prompt patient assessment and infection control decisions.
The cassette-based format allows for simple visual interpretation via distinct red test lines corresponding to each virus type, alongside a built-in procedural control line. Positive results indicate active HPIV infection, supporting early intervention and appropriate patient management.
With validated performance and high specificity against other respiratory viruses and bacteria, the EZER™ HPIVs Antigen Rapid Test is a reliable solution for routine respiratory diagnostics and point-of-care testing
Each kit contains:
20 EZER™ HPIVs Antigen Rapid Test devices
20 sterile nasopharyngeal swabs
20 extraction tubes prefilled with extraction buffer
20 dropper nozzles
1 tube stand
1 package insert with instructions for use
The test detects Human Parainfluenza Virus antigens through immunochromatographic analysis. When HPIV antigen is present, a red line appears in the corresponding test region (T1, T2, and/or T3) along with the control (C) line, confirming a valid result.
Human Parainfluenza Viruses are a common cause of acute respiratory tract infections, particularly in infants, young children, the elderly, and immunocompromised individuals. HPIV-1, HPIV-2, and HPIV-3 are associated with illnesses such as croup, bronchiolitis, pneumonia, and upper respiratory infections.
Because early symptoms often overlap with other viral respiratory diseases, rapid antigen detection plays a critical role in:
Early differentiation of respiratory pathogens
Timely clinical decision-making
Infection control and cohorting
Reducing unnecessary antibiotic use
HPIV antigens are most reliably detected during the early phase of infection, making rapid testing especially valuable shortly after symptom onset.
The EZER™ HPIVs Antigen Rapid Test is developed by Genesis Biotech and uses monoclonal antibodies specific to the nucleoproteins of HPIV types 1, 2, and 3. The assay incorporates color microsphere–labeled antibodies to enable clear visual interpretation.
Performance summary:
Sensitivity:
HPIV-1: 91.3%
HPIV-2: 95.0%
HPIV-3: 89.7%
Specificity: 100% for all three types
Overall agreement: up to 98.1%
Time to result: 15 minutes
No cross-reactivity was observed with common respiratory viruses such as Influenza A/B, RSV, Adenovirus, Rhinovirus, Human Coronaviruses, or bacterial respiratory pathogens.
The test is validated against cell culture methods and is suitable for routine clinical use.
Sample types:
Nasopharyngeal swabs
Nasal aspirates
Test procedure:
Allow test device and samples to reach room temperature
Extract the sample using the provided extraction buffer
Add 3 drops of extracted sample to the test cassette
Read results at 15 minutes (do not interpret after 30 minutes)
Result interpretation:
Positive: Control line (C) + one or more test lines (T1, T2, T3)
Negative: Control line (C) only
Invalid: No control line
The simple workflow and visual readout make the test suitable for both laboratory and point-of-care environments.
The EZER™ HPIVs Antigen Rapid Test is intended for:
Diagnosis of acute respiratory infections
Pediatric and hospital respiratory screening
Emergency department testing
Infection control and outbreak management
Point-of-care use in decentralized healthcare settings
By enabling rapid identification of HPIV infections, the test supports early clinical decisions, appropriate patient isolation, and improved respiratory disease management.
