Lot Release Testing

Lot release testing includes physical and chemical testing to ensure that the product meets the defined specifications. It is not only a key component of the quality control process for biologics, but also the basis for drug development. Before a biological product can be released for use, sale or export, lot release testing must be performed. We have the ability to provide you with lot release testing to help your product eventually enter the market.

The importance of lot release testing for vaccines

As vaccine products are manufactured on a larger scale and the global supply chain grows, control of their quality and consistency is particularly important. Vaccine lot release testing is necessary to monitor critical quality attributes (CQA) and to ensure the continued production of high quality and well-characterized vaccine products. This is because vaccines are used in healthy normal populations. If strength of active components (potency) in a lot or batch of a vaccine is suboptimal, impact of using such a suboptimal lot will not be known for a very long period (years), because benefits of vaccination against a disease are not visible immediately and the protection is not on an individual basis. Similarly, if there are safety issues with a particular lot or batch of a vaccine, the impact will be devastating as a large number of healthy normal individuals (whole populations, usually pediatric population) receive vaccines.
