Method Validation is an activity of demonstrating, as per the standards of good assembling practice, that any strategy, process, gear, material, action, or framework really prompts the normal result. Acceptance is an orderly way to deal with get-together and investigating adequate information which will give sensible certification (recorded proof), based upon logical judgment, that a procedure, when working inside determined parameters, will reliably create results inside foreordained particulars It is a reported proof which gives a high level of confirmation that a particular procedure will reliably create an item meeting its foreordained determinations and quality properties and attributes In general, analytical methods can be said to consist of a measurement stage, which may or may be preceded by an isolation stage. It is necessary to establish that the signal produced at the measurement stage, which has been attributed to the analyte, is only due to the analyte and not from the presence of something chemically or physically similar or arising as coincidence.
Important requirements of method validation have been mentioned in the succeeding paragraph. Method validation is is an action to verify that any process, procedure, activity, material, system, or equipment used in manufacture or control can, will, and does achieve the desired and intended results, therefore, even a modified approach can be adopted with meticulous measures.
Limit of detection: Limit of detection (LOD) is defined as the lowest concentration of an analyte in a sample that can be distinguished from a blank. It is expressed as a concentration at a certain specified signal-to-noise ratio, usually two-or three to one. Where measurements are made at low analyte level e.g. in trace analysis, it is important to know what is the lowest concentration of the analyte that can be confidently detected by the method. as a method is used at lower and lower levels the precision deteriorates. Effectively the measurement becomes subject to increasing 'noise'. The limit of detection is the point at which, with a defined probability, it becomes possible to distinguish signal from noise. Normally 95% probability, is the relevant level.
There are several important features of Validation like Increased throughput, reduction in rejections and reworking, reduction in utility costs, avoidance of capital expenditures, fewer complaints about process-related failures, reduced testing in-process and in finished goods, more rapid and reliable start-up of new equipment, easier scale-up from development work, easier maintenance of equipment, improved employee awareness of processes and more rapid automation.
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.
