Product Description
COVID-19 Antigen Rapid Test Cassette Overview
Professional lateral flow immunoassay for qualitative detection of SARS-CoV-2 nucleocapsid antigens in nasopharyngeal and oropharyngeal swab specimens from individuals suspected of COVID-19 by healthcare providers.
Storage and Stability Specifications
- Storage temperature: 4-30°C (40-86°F)
- Stable within printed expiration date on labeling
- Use within one hour after opening sealed pouch
- Avoid prolonged exposure to hot and humid environments
Sample Collection Procedures
Nasopharyngeal Swab Collection
Insert flexible shaft swab through nostril parallel to palate until resistance is encountered. Gently rub and roll swab, leave in place to absorb secretions, then remove while rotating. Collect from both nostrils if necessary.
Oropharyngeal Swab Collection
Insert swab into posterior pharynx and tonsillar areas. Rub over both tonsillar pillars and posterior oropharynx while avoiding contact with tongue, teeth, and gums.
Specimen Preparation Protocol
- Add extraction reagent to tube and place on workstation
- Insert swab into extraction tube and roll at least 5 times while pressing against tube bottom and sides
- Leave swab in extraction tube for one minute
- Remove swab while squeezing tube sides to extract liquid
- Insert dropper tip into extraction tube securely
Testing Procedure Guidelines
- Equilibrate test device and specimens to 15-30°C (59-86°F) before testing
- Remove test cassette from sealed pouch
- Transfer 3 drops (approximately 100μL) to specimen well
- Interpret results at 15 minutes - do not read after 20 minutes
Result Interpretation Guide
| Result Type | Visual Indicators | Interpretation |
|---|---|---|
| Positive | Two colored lines: control region (C) and test region (T) | Presence of SARS-CoV-2 nucleocapsid antigen detected. Requires clinical correlation with patient history and additional diagnostic information. |
| Negative | One colored line in control region (C), no line in test region (T) | Presumptive negative result. Does not preclude infection and should not be used as sole basis for treatment decisions. |
| Invalid | Control line fails to appear | Insufficient specimen volume or incorrect technique. Repeat test with new cassette. |
Important Note: Positive results indicate presence of viral antigens but do not rule out bacterial infection or co-infection with other viruses. Negative results are presumptive and may require confirmation by molecular testing methods for comprehensive patient management.
