In-process high quality Manage (IPQC) and finished solution quality control (FPQC) tests are important for ensuring the standard of parenteral and ophthalmic products. Essential IPQC tests include things like leakage testing making use of dye tub tests and clarity testing to look for particulate matter. Vital FPQC tests include sterility testing working with membrane filtration or immediate inoculation techniques, pyrogen testing utilizing the Limulus Amoebocyte Lysate test, and information uniformity and bodyweight checks.
