Introduction
Validation trials are an essential part of the process of confirming the analytical methods used to determine the concentration of test articles in animal tissues and drug dosage forms. In the United States, specific requirements must be met during validation trials to ensure that the analytical methods are VALID, reliable, and reproducible. This article will delve into the specific requirements for validation trials conducted in the United States to confirm the analytical methods used for determining the concentration of a test article.
Specific Requirements for Validation Trials
1. Specificity
Specificity is the ability of an analytical method to accurately measure the concentration of the test article in the presence of other components that may be present in the sample. During validation trials, the specificity of the method should be demonstrated by showing that it can accurately measure the concentration of the test article without interference from other compounds.
2. Accuracy
Accuracy is the closeness of the measured value to the true value of the test article concentration. During validation trials, the accuracy of the method should be determined by comparing the measured values to known reference values. The method should demonstrate a high level of accuracy in determining the concentration of the test article in the samples.
3. Precision
Precision refers to the repeatability and reproducibility of the analytical method. In validation trials, the precision of the method should be evaluated by conducting multiple measurements of the same sample and calculating the variability between the results. The method should demonstrate high precision, with low variability between measurements.
4. Linearity
Linearity is the ability of an analytical method to provide results that are directly proportional to the concentration of the test article in the samples. During validation trials, the linearity of the method should be assessed by analyzing samples with different concentrations of the test article and examining the relationship between the measured values and the actual concentrations. The method should demonstrate good linearity over a specified range of concentrations.
5. Range
The range of an analytical method refers to the concentration range over which the method can accurately measure the test article in the samples. During validation trials, the range of the method should be established by testing samples with low, medium, and high concentrations of the test article. The method should demonstrate the ability to accurately measure the test article within the specified range of concentrations.
6. Robustness
Robustness is the ability of an analytical method to provide reliable results under different conditions such as changes in temperature, humidity, or other environmental factors. During validation trials, the robustness of the method should be evaluated by making deliberate changes to the experimental conditions and assessing the impact on the results. The method should demonstrate robustness by producing consistent and reliable results under varying conditions.
Conclusion
Validation trials are an essential step in confirming the analytical methods used to determine the concentration of test articles in animal tissues and drug dosage forms. In the United States, specific requirements must be met during validation trials to ensure that the analytical methods are VALID, reliable, and reproducible. By addressing parameters such as specificity, accuracy, precision, linearity, range, and robustness, validation trials help to establish the suitability of the analytical methods for determining the concentration of a test article.
