Introduction

The antigen swab test has become an essential tool in detecting active infections, particularly those caused by viruses such as SARS-CoV-2. Due to its rapid detection capabilities, it has become a cornerstone in managing public health responses.

Definition of Antigen Swab Test

An antigen swab test is an in vitro diagnostic test that identifies the presence of specific antigens from a pathogen, using specimens obtained via a nasal or throat swab. It provides results at an accelerated speed compared to traditional assays, enabling timely intervention.

Production Process of Antigen Swab Test

The production of antigen swab tests involves several critical steps ensuring high specificity and sensitivity:

1. Selection of Target Antigens: Antigens are selected based on their uniqueness and abundance in the pathogen structure.
2. Antibody Development: Monoclonal antibodies are developed to specifically bind to the target antigens.
3. Swab Manufacturing: Swabs are manufactured using materials that ensure optimal specimen collection and stability.
4. Lateral Flow Device Assembly: Swabs are incorporated into lateral flow assay devices that visually indicate antigen presence.
5. Quality Control and Validation: Each production batch undergoes stringent tests for efficacy and reliability.

Analytical Parameters of Antigen Swab Tests

The effectiveness of an antigen swab test is assessed through several parameters:

• Sensitivity: Defined as the test’s ability to correctly identify those with the antigen. Desired sensitivity rates are above 90%.
• Specificity: The test’s ability to correctly identify those without the antigen, ideally above 95%.
• Result Time: Results are typically available within 15-30 minutes, enhancing rapid decision-making.
