Introduction

Antigen self-test kits have become a primary tool in the UK for rapid detection of COVID-19 cases. These kits offer individuals a convenient way to test for SARS-CoV-2 at home without the need for healthcare professionals, thus aiding in the control of virus transmission.

Understanding Antigen Self-Test Kits

Antigen tests detect proteins from the virus and are designed to identify current infections. They are most effective within the first week of symptom onset, with a sensitivity of approximately 70-80% and specificity around 99%.

Steps to Use Antigen Self-Test Kits

1. Preparation: Wash hands thoroughly before starting the test. Ensure the testing area is clean and well-lit.
2. Sample Collection: Use the swab provided to collect a sample from the nasal cavity. Insert the swab into the nose until resistance is felt and rotate it gently for 10-15 seconds.
3. Testing: Place the swab in the provided extraction buffer. Ensure the swab is in the solution for at least 1 minute. Squeeze the swab against the tube to extract the liquid.
4. Application: Place a specified number of drops (usually 2-3) onto the test device as indicated in the instructions.
5. Result Interpretation: Wait for the time specified on the kit (usually 15-30 minutes) before reading the results.

Important Considerations

• Follow the manufacturer's instructions carefully for accurate results.
• Store the testing kit at the temperature specified (typically between 2°C to 30°C).
• Confirm negative results with a PCR test if symptoms persist.
• Dispose of the testing materials safely to avoid contamination.

Interpretation of Results

Results are typically displayed as follows:

• Positive: Two lines appear, one next to the Control (C) and another next to the Test (T) line.
• Negative: Only one line appears next to the Control (C) line.
• Invalid: No lines or only a Test (T) line appears. Retest with a new kit.
