Quality control involves sampling, inspecting and testing of starting materials, in process, intermediate, bulk, and finished products. It also includes where applicable, environmental monitoring programs, review of batch documentation, sample retention program, stability studies and maintaining correct specifications of materials and products.
l Reprocessing
The methods of reprocessing should be evaluated to ensure that they do not affect the quality of the product.
Additional testing of any finished product which has been reprocessed should be performed.
l Records for Quality Control
