Määritysanalyysin

Määritysanalyysi, often translated as assay development or characterization analysis, refers to the process of establishing and validating a method to accurately quantify or identify a specific substance or phenomenon. This is a crucial step in various scientific and industrial fields, including drug development, diagnostics, environmental monitoring, and food quality control.

The primary goal of määritysanalyysi is to create a reliable and reproducible procedure. This involves several key stages. First, a target substance or characteristic is defined. Then, a suitable analytical technique is selected, which could range from simple chemical titrations to sophisticated spectroscopic or chromatographic methods. Critical parameters of the chosen method are then optimized to ensure sensitivity, specificity, accuracy, and precision.

Validation is a cornerstone of määritysanalyysi. This rigorous process involves systematically assessing the method's performance against predefined criteria. Common validation parameters include linearity, range, limit of detection (LOD), limit of quantitation (LOQ), accuracy, precision (repeatability and intermediate precision), specificity, and robustness. A validated assay provides confidence in the results generated and ensures that the method is fit for its intended purpose.

The output of a successful määritysanalyysi is a well-defined analytical protocol that can be routinely used to measure the target of interest. This standardized method allows for consistent data collection, comparison of results across different experiments or laboratories, and informed decision-making based on the analytical findings.
