Method validation is the process used to confirm that the analytical procedure employed for a specific test is suitable for its intended use. Results from method validation can be used to judge the quality, reliability and consistency of analytical results; it is an integral part of any good analytical practice. By definition method validation is the process of establishing the performance characteristics and limitations of a method and the identification of the influences which may change these characteristics and to what extent. A test or calibration Method validation, aims at providing an assurance of reliability of data. The ongoing reliability and comparability of data can be guaranteed only through the implementation of quality assurance system including the application of method validation according to international accepted procedures and performance criteria.
The minimum requirements of method validation are discussed below. In the case of methods developed from scratch in-house a much more comprehensive approach covering the other parameters described below will be required. Few laboratories, however, take this approach and the norm is to adopt and perhaps slightly modify standard methods.
The limit of quantification (LOQ) is defined as the lowest concentration of an analyte in a sample that can be determined with acceptable precision and accuracy under the stated operational conditions of the method. Like LOD , LOQ is expressed as a concentration, with the precision and accuracy of the measurement also reported. The overall effect is that the laboratory will state that an analyte is detectable between LOD and LOQ but will not offer a result as the precision is unacceptable. Below LOD the analyte is not detected and above LOQ it is measured. Accuracy is popularly used to describe the measure of exactness of an analytical method, or the close of an agreement between the value, which is accepted as a conventional, true value or as an accepted reference value, and the value found. Accuracy is properly a qualitative concept and the correct term is 'bias'.
There are a few vital components of Validation shirking of capital consumptions, less grievances about procedure related disappointments, decreased testing in-procedure and in completed products, more quick and solid start-up of new gear, Increased throughput, lessening in dismissals and adjusting, diminishment in utility expenses, less demanding scale-up from advancement work, less demanding support of hardware, enhanced worker familiarity with procedures and more fast mechanization.
Since the mid-1970s validation has become an increasingly dominant influence in the manufacture and quality assurance of pharmaceutical products. In 1976 the FDA proposed a whole set of current GMP regulations which were revised several times. In several major countries GMP regulations are considered official law and noncompliance is prosecutable. Additional compliance policies, guides, and guidelines are not legally binding. However, the pharmaceutical industry follows them as a part of good management and business practice. The demands in the health care industry are greater than ever because customers (government, physicians, pharmacists, patients, and health insurance companies) are more interested in product safety, efficacy, and potency and asking value for money. Pharmaceutical products' quality must be consistent and meet the health and regulatory requirements. The pharmaceutical industry has the obligation to validate GMP to their process to be in compliance with GMP requirements.
