Setting the Standard

Defining Best Practices in Method Evaluation

CLSI’s evaluation protocol standards provide detailed explanations and instructions for the evaluation of test method performance characteristics such as precision and accuracy.  These standards equip labs with the information needed to comply with the latest best practices and accreditation requirements. 
 
In addition to evaluation protocol standards, CLSI has developed implementation and establishment guides and tools designed for use by laboratory scientists when performing verification and validation testing. Minimum protocols are provided in the establishment and implementation guides, including how to select appropriate samples and analyze data. 
 

CLSI method evaluation guidance supports developers of both commercially available in vitro devices (IVDs) and laboratory developed tests (LDTs), and follows the life of a test through establishment and implementation. CLSI EP19 presents a framework that all CLSI evaluation protocol standards fall into.
 

CLSI guidance is developed through a robust consensus process that includes the open and transparent input of all affected stakeholders from industry, government, and  professions.

Guidance to Ensure Your Test Meets Requirements 

CLSI’s library of evaluation protocols is based on the framework in EP19 and designed to ensure each stage and type of testing is compliant with regulatory requirements. 

Featured Product

CLSI Method Navigator™

CLSI’s newly updated Method Navigator helps developers of both commercially available IVDs and LDTs identify, understand, and meet regulatory requirements with ease.  This comprehensive resource includes regulatory requirements, checklists, and navigation to specific document guidance necessary for meeting requirements at each life phase of a test.

Latest Method Evaluation Insights

Method Evaluation
CLSI has published a white paper, EP43—Implementing a Laboratory Test Under Emergency Use Conditions. EP43 covers public health emergencies (PHEs) in general, the ways in which emergency use authorizations (EUAs) may be used, and the ramifications of EUAs for medical laboratories and other testing sites.
Method Evaluation
Medical laboratory tests are essential to the clinical management of patients. It is important to express numerical results with additional properties, such as linearity.
Quality Management
Most laboratories use methods such as QC, equipment calibration measurement, QA measurements of process performance, and more recently, implementation of a quality management system, to determine the quality of examination results and laboratory services.
