What quality systems do you have in place to make sure the samples are not mixed up?

Our team of highly skilled and qualified scientists adhere to strict laboratory requirements of the international quality standard, ISO/IEC 17025 (an accreditation for testing and calibration laboratories). Included in this is the requirement for all work to be witnessed and double-checked by a second competent member of scientific staff. We have every confidence in our team and supporting Quality Management System and as such, should you have reasonable cause for doubt, we are happy to repeat any case should your client require confirmation. On occasion, we are asked to reinterpret their data files from tests conducted by other laboratories. Unfortunately, we are not prepared to do this. If you are unsure of the data from another laboratory and wish to have it checked, we would need to register a new case in our system and repeat the entire sampling and analysis procedure.
