Introduction

Antigen rapid test kits have become a crucial tool in the detection and management of infectious diseases. This article provides a detailed examination of the manufacturing process of these test kits, highlighting the specific steps and quality control measures involved.

Manufacturing Process of Antigen Rapid Test Kits

Conceptualization and Design

The initial phase involves the conceptualization and design of the test kit. This phase requires understanding the target antigen-protein interactions and designing a test that can reliably identify the presence of an antigen within a predetermined limit, often nanogram (ng) levels per milliliter.

Materials and Components

Key materials include absorbent pads, nitrocellulose membranes, and conjugate pads. The nitrocellulose membrane is prepared with antibodies specific to the target antigen.

• Nitrocellulose membrane, thickness: 100-150 µm
• Absorbent pad, dimensions: 20x30 mm
• Conjugate pad impregnated with secondary antibodies, concentration: 1 mg/ml

Assembly Line

The assembly of rapid test kits involves the careful alignment of different components. Automation is heavily employed to ensure precision, with production rates of up to 10,000 kits per hour.

Quality Control

Stringent quality control tests are conducted to validate the sensitivity and specificity of the test kits. The typical sensitivity must be over 95%, while specificity targets above 99% are common.

Joinstar Company Solutions

Joinstar Biomedical Technology Co., Ltd. has developed advanced antigen rapid test kits featuring improved sensitivity and ease of use. The company integrates proprietary colloidal gold labeling techniques in their test kits, which improves visual clarity and reduces testing errors.
