SARS-CoV-2 Antigen Rapid Test Kit

How does the SARS-CoV-2 Antigen Rapid Test Kit work?

Abbexa's SARS-CoV-2 Antigen Rapid Test Kit is a qualitative lateral flow immunochromatographic assay for the detection of SARS-CoV-2 antigens in human oropharyngeal, nasal and nasopharyngeal swabs.

The cassette contains monoclonal antibodies against SARS-CoV-2 / COVID-19 conjugated to gold nanoparticles, which bind to any SARS-CoV-2 antigen present in the sample. Monoclonal antibodies against SARS-CoV-2 are coated in the test region on the nitrocellulose membrane, which bind to the antigen-antibody complex and create a coloured line due to the gold nanoparticles. A control region on the upper end of the cassette confirms if the test has been successful.

How quickly are the results obtained?

Within 10 minutes.

Assay Protocol

Place the cassette on a level surface at room temperature (15-25°C, 59-77°F).	Remove the seal on the extraction buffer tube.	Place the swab in the extraction buffer tube and rotate 10 times, squeezing against the tube walls to extract the most sample.
Remove the swab and cover the tube with the buffer tube cap.	Add 3 drops of the extracted sample into the sample well.	Wait 10 minutes.
Read the results (see interpretation of results section).

Results Interpretation

• Positive result: A colored line is observed in both the control (C) section and the test (T) section.
• Negative result: A colored line is observed in the control (C) section but not the test (T) section.
• Invalid result: No colored line is observed in the control (C) section.

#1 Positive

#2 Negative

#3 Test Failure

#4 Test Failure

Please note that this kit is for research use only (RUO) and the results are for reference only. It is recommended to use this kit with another method to confirm the results (e.g. by PCR).

How accurate is the SARS-CoV-2 Antigen Rapid Test Kit?

Based off a sample of 158 people (31 positive and 127 negative), the test has a sensitivity and specificity of 90.32% and 99.21%, respectively.
