The Raw Materials that Drive Diagnostics Forward

The in vitro diagnostics (IVD) industry plays a vital role in healthcare by providing tests, reagents and instruments that detect and monitor diseases. Behind every diagnostic test is a complex set of raw materials that must work precisely together to deliver accurate, reliable results. With new technologies enabling more advanced and personalized testing, the demand for high-quality raw materials continues to grow. This article explores the key raw material categories that fuel diagnostics development and highlights some of the industry's material supply challenges.

Antigens and Antibodies

Antigens and antibodies are fundamental components in many IVD Tests that rely on antigen-antibody reactions. Antigens are substances that cause the body's immune system to produce specific antibodies to combat them. During testing, antigens are introduced to trigger an antibody response that can be measured.

Common diagnostic antigens include:

- Disease markers such as proteins or hormones that indicate a health condition's presence

- Bacteria and viruses used to detect specific infections

- Allergens to identify allergic reactions

Antibodies are part of the immune system's targeted defense plan against antigens. Monoclonal antibodies are antibodies produced identically in the lab and are widely used in IVDs given their high specificity. Ensuring a reliable supply of purified monoclonal and polyclonal antibodies is essential.

Reagents

Reagents are chemical components or substances used to carry out diagnostic testing, usually by detecting or measuring biomarkers. Common reagent categories include enzymes, buffers, proteins, nucleic acids, antibodies and others. Reagents must be rigorously quality controlled to deliver accurate and repeatable test results.

Some key reagents and challenges faced in their supply include:

- Enzymes for tumor marker tests that require consistent activity

- Buffers for maintaining stable pH environments during reactions

- Proteins for assays that need uniform quality across lots

- Nucleic acids such as RNA and DNA oligos requiring sequence specificity

- Antibodies prone to lot-to-lot variability impacts

Plastic and Glass Components

Plastics and glass make up much of the consumable test components and instrumentation used in diagnostics. Vast numbers of plastic tubes, strips, cassettes and containers are needed to handle sample collection and testing workflow. High-quality glass and molded plastics withstand the rigorous conditions of automated analyzers.

Sourcing the right plastic and glass materials requires considering their:

- Chemical compatibility with samples and reagents

- Optical clarity for instrumentation readings

- Strength and flexibility at various temperatures

- Manufacturability for high-volume production

- Regulatory approvals and material certifications

Supplies of diagnostic-grade plastics and glass can be challenging given the industry's demanding standards and global supply chain complexities. Shortages or inconsistent quality can risk delays or limit new product development. Material suppliers constantly collaborate to deliver specialized solutions.
