Laboratory Proficiency Testing Market Size, Share & Trends Analysis growing at a CAGR of 6.4% from 2025 to 2030

One of the key growth drivers is the increasing focus on water testing to identify micropollutants, contaminants, and microorganisms in freshwater and wastewater. Common microbial contaminants include Legionella, Legionella pneumophila, Salmonella, enterococci, E. coli, Pseudomonas aeruginosa, coliforms, and staphylococci. Proficiency testing is critical in water microbiology as it ensures laboratories can reliably detect and quantify such contaminants. Through blind sample distribution, proficiency testing programs evaluate a laboratory’s capability to perform accurate and consistent water quality analysis, thus safeguarding public health.

In addition to microbial testing, laboratory proficiency testing also plays an essential role in measuring endotoxin and pyrogen levels in water, particularly for pharmaceutical manufacturing, medical device production, and dialysis. These toxic substances, originating from bacteria, can have severe health implications. Laboratories must demonstrate their competence in using advanced methods such as Limulus Amebocyte Lysate (LAL) assays to ensure precision in endotoxin detection. Reliable results from such testing are  vital for meeting regulatory standards and ensuring water safety.
