PROFICIENCY TESTING PROVIDER
Top notch and cost effective PT
QD Labs provides you with ISO/IEC 17043-accredited PTs with a focus on polymeric materials testing. Proficiency testing is vital for ensuring accuracy and reliability in material analysis and product evaluation. It provides industry professionals with the tools to benchmark their methodologies against standardized tests, maintaining high-quality standards and fulfilling requirements of ISO/IEC 17025.
SAMPLING
Risk and conformity
Current methods for assessing compliance with regulations, e.g. in the area of food safety, ignore historical data, although this is crucial for improving the accuracy and reliability of any kind of conformity assessments. The integration of Bayesian approaches is key here. These approaches provide a sophisticated and robust framework for incorporating historical data. This applies to the assessment of individual measured values and measurement methods as well as to the assessment of sampling methods. QD labs LP provides convenient and powerful tools to achieve exactly this.
MEASUREMENTS
Accuracy and uncertainty
At QD Labs LP, we are dedicated to the precise determination of the level of accuracy in your test results and examinations, test procedures, and test kits. Our company leads the development of advanced mathematical methods, experimental design concepts, and innovative software tools to quantify and improve the accuracy and reliability of physical, chemical, biological, microbiological, and molecular biological measurement procedures and examinations.Our proficiency tests and other quality assurance services examine and improve your measuring, sampling, and AI systems. We provide maximum accuracy in your systems by finding and minimizing errors. Our tailored software tools validate and verify your measuring equipment for exact and consistent results in any scenario.In addition to traditional methods such as calculating Z-scores, we offer tools to measure the utility of a measurement method. This utility assessment allows for the first time the linking of the expected measurement uncertainty from each laboratory with the observed measurement deviation. This approach not only ensures compliance with statistical benchmarks but also aligns with the practical requirements and real-world applications of your methods, ensuring they are truly fit for purpose.
AI METHODS
Fairness and benchmarking
At QD Labs LP, we combine deep expertise in artificial intelligence (AI) with comprehensive knowledge in mathematical and statistical experimental design. This unique combination enables us to develop novel methods for determining the level of accuracy of AI methods. We utilize highly developed statistical techniques that go far beyond conventional approaches. Our special expertise lies not only in identifying errors within AI models but also in quantifying the benefits these models provide, even in the presence of unavoidable errors. If you need a thorough characterization of the performance of an AI system, we have the technology and expertise to provide comprehensive and precise evaluations, ensuring you understand both the limitations and the significant advantages of your AI solutions.
