Validation procedures

Processing validated for use with any subsequent procedure. Validation may be specific to analyte and/or sample matrix... 

The results are extended (move 3) in step 4, Procedure Validation. The extended information informs the viewer that (1) results were linear and reproducible and (2) the technique also works with a certified reference standard (Table 2). These results build logically on the principal finding of the work, that with saponification RGBs can be detected in full-fat milk. 

Procedure Validation. Calibration results were linear (R > 0.994) and reproducible (RSD < 11.0 %) over a wide range of concentrations. Recoveries >75% were achieved with a certihed milk sample (Table 2).

Computer control of CIP systems is common and programmed recipes can help control the consistency and quality of the cleaning procedure. Validated computer systems used for CIP should be considered.

The quality of the new excipient, SBE7-P-CD, was built in by the design of the manufacturing process. The product s quality was created by understanding the synthesis and work-up procedures, the requirements for the raw materials, and the parameters that affected the reaction and isolation procedures. Validation of the process and cleaning procedures ensured a quality product, and this was confirmed by the analytical characterization of the product. 

Failure to establish yields or acceptable levels of rejects for both in-process and finished product Failure to conduct stability studies Manufacturing equipment not identified and/or qualified Inadequate training of employees working in aseptic operations Inadequate process change procedures Validation protocols that lack acceptance criteria Incomplete investigations of laboratory failures Failure to follow United States Pharmacopeia (USP) procedures for the bacterial endotoxin test... 

The concept of validation came up in the 1970s in association with sterilization procedures and was extended to all steps of pharmaceutical manufacturing procedures. Validation means proving that any and all procedures, processes, equipment, material, operations, and systems comply with the expected performance. Well-planned and well-conducted validation studies constitute GMP principles once they guarantee a consistently safe and efficacious final product. Validation is important for companies, first for QA, and also for cost reduction, decreasing failures, rejection, reworks, recalls, and complaints. The positive aspect of validation is an increase in productivity, as a consequence of a well-controlled process. Validation is required by the regulatory agencies of many countries. 

Baer et al. during 1986 to 1988. Urine was screened by methods in effect in the federal probation system THC metabolite and opiates were screened by EMIT and confirmed by high performance liquid chromatography (HPLC) at cutoffs of 100 and 500 ng/mL, respectively. Cocaine metabolites and PCP were screened by thin-layer chromatography (TLC) at cutoffs of 2000 and 500 ng/mL, respectively, and confirmed by GC. Hair testing was by RIA. The RIA procedures, validated by GC/MS, showed no false positives due to cross-reactivity effects.
