The global laboratory proficiency testing market size was estimated at USD 1.5 billion in 2024 and is projected to reach USD 2.13 billion by 2030, growing at a CAGR of 6.43% from 2025 to 2030.  This growth is fueled by several key sectors, including water testing, cannabis testing, and food safety, which are driving demand for proficiency testing services.

A major factor contributing to market expansion is the heightened emphasis on water testing, aimed at detecting micropollutants, contaminants, and microorganisms in both freshwater and wastewater sources. Common microbial contaminants targeted include Legionella, Legionella pneumophila, Salmonella, enterococci, E. coli, Pseudomonas aeruginosa, coliforms, and staphylococci. Proficiency testing is critical in water microbiology because it verifies that laboratories have the ability to accurately detect and quantify these harmful organisms. By distributing blind samples, proficiency testing programs assess laboratories' performance in delivering consistent and reliable water quality analyses, thereby playing a vital role in protecting public health.

Beyond microbial contamination, proficiency testing is also essential for measuring endotoxin and pyrogen levels in water, especially in industries such as pharmaceutical manufacturing, medical device production, and dialysis treatment. These substances, which originate from bacteria, pose serious health risks. Laboratories must demonstrate expertise in detecting endotoxins using advanced techniques like Limulus Amebocyte Lysate (LAL) assays. Accurate and dependable results from these tests are crucial for meeting regulatory requirements and ensuring the safety of water used in sensitive applications.
