I'd have a tricky question.
For the controlled room monitoring, we have an agreement with the lab measuring the contamination of air and surfaces (bioburden). This lab has a GMP certificate focused on: 1 Manufacturing operation (Batch certification and Quality control testing) 2 Importation of medicinal products, etc.
For the measurement of the material contamination (bioburden), we have an agreement with the lab which is 17025 certified (for determination of endotoxins, bioburden etc).
And for the measurement of the particle count, we have an agreement with the lab which is also 17025 certified.
My question is, shouldn't we require the same certification from all labs or is this attitude correct? How can we prove the auditor the correctness of this choice (if it is correct). Still, it does'nt seem to be clear for the companies how to choose the testing lab based on the certification.
Thanks a lot!
