The purpose of the SARS-CoV-2 Antigen Rapid Test is to qualitatively detect SARS-CoV-2 antigens in a nasopharyngeal swab sample, supporting rapid diagnosis of active COVID-19 infection and aiding clinical decisions during the pandemic.
How to Prepare
- No fasting is required for this test.
- Duly filled Covid-19 Clinical Information Form (Form 44) / SRF ID is mandatory.
- Sample collected in VTM is unacceptable.
- Nasopharyngeal swab must be submitted in the extraction buffer provided with the kit.
- Transport and process the sample at room temperature within 1 hour.
Doctor's Notes
Reviewed by Dr Kothari Ramesh Shantilal — MBBS, MD (Microbiology) · Reg. No. 27670
"Antigen testing is useful when rapid decisions are needed, but a negative result should not be used as the sole basis to rule out COVID-19. Clinical correlation and, when needed, RT-PCR confirmation remain important."

Test Parameters & Specifications
Sample Stability
- Sample collected in Viral Transport Medium (VTM)
- Missing or incomplete Covid-19 Clinical Information Form (Form 44) / SRF ID
- Unlabelled or mislabelled sample
- Improperly transported or delayed sample beyond 1 hour at room temperature
Understanding Your Results
Positive (Detected)
SARS-CoV-2 antigen was detected in the sample. This suggests active COVID-19 infection. Follow the current isolation protocol and consult a physician for further management.
Negative (Not Detected)
SARS-CoV-2 antigen was not detected in the sample. This does not rule out COVID-19. If symptoms or exposure history suggest infection, RT-PCR may be considered.
Invalid
The test result could not be interpreted. A repeat test should be performed using a new kit and specimen.
Consult a doctor if you have symptoms suggestive of COVID-19, if you receive a positive antigen test result, or if you develop warning signs such as difficulty breathing, persistent chest pain, confusion, inability to stay awake, or bluish lips or face.
Limitations
- ⚠A negative result does not exclude COVID-19 infection
- ⚠The test is generally less sensitive than RT-PCR
- ⚠Antigen levels vary during the course of illness and may be lower in early or late infection
- ⚠Results should be interpreted together with clinical symptoms and exposure history
- ⚠This test is not intended for antibody detection or immunity assessment
Risks & Considerations
- ●Mild discomfort or gagging during nasopharyngeal swab collection
- ●Temporary nasal irritation or minor bleeding
- ●Very small risk of vagal response in sensitive individuals
Interfering Factors
- ●Improper nasopharyngeal swab collection may affect test accuracy
- ●Inadequate or insufficient specimen material
- ●Excessive blood or mucus on the swab
- ●Delayed testing beyond recommended time after sample collection
- ●Failure to follow the test kit storage and handling instructions
