Introduction

The COVID-19 pandemic has necessitated the development of convenient and accessible testing solutions. Antigen self-test kits are designed for laypersons to detect the presence of SARS-CoV-2 antigen, offering results within 15–30 minutes. These over-the-counter tests are vital for quickly identifying infections and limiting spread. This article provides detailed insights on how to effectively use these kits.

Components of a COVID Antigen Self-Test Kit

A typical COVID antigen self-test kit includes:

• Test device containing the detection antibody
• Buffer solution for sample processing
• Sterile swab for specimen collection
• Instructions for use

Step-by-Step Guide to Using a COVID Antigen Self-Test Kit

1. Preparation: Wash hands with soap and water. Ensure all components are at room temperature.
2. Specimen Collection: Use the sterile swab provided to collect a nasal or throat specimen according to the instructions.
3. Sample Processing: Insert the swab into the buffer solution and mix thoroughly.
4. Testing: Apply the processed sample to the test device as instructed.
5. Wait for Results: Allow 15–30 minutes for the results to develop. Do not read results after the time specified.

Interpreting Results

Upon completion of the test, results can be interpreted as follows:

• Positive: Two colored lines appear (one in the control line region and another in the test line region). This indicates the presence of the SARS-CoV-2 antigen.
• Negative: A single colored line appears in the control line region. No line appears in the test line region.
• Invalid: No lines appear, or only the test line appears, suggesting an error in testing.

Accuracy and Limitations

Antigen self-test kits offer a sensitivity between 85-95% and specificity of 97-99%. While highly effective for rapid testing, false negatives can occur, particularly in low viral load scenarios. It is advised to consult healthcare professionals for confirmatory testing if symptoms persist despite a negative result.
