In the in vitro diagnostics (IVD) industry, batch consistency of reagent raw materials is crucial. It is directly related to the stability of IVD reagent performance, which in turn affects clinical diagnostic results. From medical laboratory testing to large institutions, stable and reliable IVD reagents are the foundation for accurately assessing the condition, and the source of these reagents lies in whether upstream suppliers can ensure product batch consistency. So, what measures do IVD reagent raw material suppliers need to take to achieve this key goal?

Strictly control the procurement of raw materials

（1） Carefully screen suppliers

IVD reagent raw material suppliers need to establish a strict supplier screening mechanism first. When purchasing bioactive raw materials, it is necessary to thoroughly examine the supplier's technological level. In addition, the quality control system of suppliers is a focus of attention, and it is necessary to understand their full process quality control measures from raw material inspection to finished product release, as well as whether they have complete research and development capabilities, so that they can respond and solve problems in a timely manner when raw material performance is optimized or problems arise.

（2） Raw material quality inspection

The storage conditions required for different IVD raw materials vary greatly. Chemical raw materials should be stored in a suitable environment based on their chemical properties, such as isolating oxygen from easily oxidizable materials and strictly controlling the humidity of the storage environment for easily deliquescent materials. Before the raw materials are put into storage, a strict inspection system needs to be established to conduct sampling and testing on each batch of raw materials. The testing items include appearance, purity, activity, acidity and alkalinity, etc.

Optimize production process

（1） Develop standardized operating procedures

From the proportion and sequence of raw material input, to reaction time, temperature, pressure and other parameters, to the post-processing steps of finished product output, each link must have clear and accurate operating specifications. In the production process of chemiluminescence reagents, the control of reaction time may affect the synthesis efficiency and structural stability of luminescent substances. Therefore, it is necessary to strictly set these parameters and accurately regulate them through an automated control system to reduce errors caused by human operation. At the same time, a comprehensive production process traceability system should be established to record every detail of the production process in detail, including information on operators, equipment operating parameters, production time, etc. Once there is a problem of batch differences in products, it can be quickly traced back to the specific production process, making it easier to identify the cause and solve it.

（2） Regular maintenance and calibration of equipment

Long term operation of production equipment may result in issues such as wear and aging, leading to drift of production parameters and subsequently affecting batch consistency of products. So, suppliers need to develop strict equipment maintenance plans, regularly clean and maintain equipment, and replace worn parts in a timely manner. For key production equipment such as liquid chromatography and PCR amplification instruments, regular calibration should be carried out by using standard substances to calibrate the equipment, so that its detection results are highly consistent with the standard values, providing hardware support for stable and consistent product production.

Strengthen the quality control system

Timely feedback the quality inspection results to relevant teams such as the production department and R&D department. If a certain performance indicator of a batch of products is found to fluctuate during testing, the production department can investigate whether there are operational errors or equipment failures in the production process based on feedback information. The R&D department can conduct in-depth analysis from aspects such as raw material formula and production process to find improvement directions. Through cross departmental collaboration and continuous quality feedback and improvement, we continuously optimize the production process and improve the consistency level of product batches. At the same time, collect feedback from customers after using the product. If customers find batch differences in the actual application of IVD reagent raw materials, they should promptly report to the supplier, and the supplier can further improve the quality control system based on this.

IVD reagent raw material suppliers need to start from multiple aspects such as raw material procurement, production process optimization, and quality control system strengthening, and take strict measures to ensure product batch consistency. This is not only responsible for downstream IVD reagent production enterprises, but also provides a solid guarantee for clinical diagnosis.
