With over 15 years of experience and more than 400 participating laboratories across 24 countries, the Charles River Proficiency Test Program (PTP) is a quality assurance tool for limulus amebocyte lysate (LAL) users that provides confidential quarterly audits of LAL test proficiency. The PTP allows you to verify the accuracy of your LAL results by providing you with a confidential and external quarterly audit of your analysts and to confidentially compare your results to those of other laboratories. It is a mechanism by which a laboratory can demonstrate competence based on practical evaluation of LAL testing and improve procedure and methods when needed.
Using the Endosafe® PTP web interface, we work with you to verify methods, report validations, identify trends and spot possible training needs. The program is open to any LAL user looking to verify working procedures though an external source with no restrictions on methodology, reagents or instrumentation.
