We welcome your interest in the Olerup XM-ONE proficiency testing (PT) program. The programs intention is to guide clinical laboratories towards compliance with Clinical Laboratory Improvement ACT (CLIA) regulations. The Olerup XM-ONE PT program received approval by The American Society for Histocompatibility and Immunogenetics (ASHI) in 2011 as it meets the requirements set forth by the society.

We provide PT Survey’s for laboratories which are validated and interested in continued surveillance of their performance. New interested laboratories should print and complete the registration form (link below), and email or fax to Olerup Inc (att. Eileen Tully). Laboratories already registered need only to order subscribtion. For all new laboratory subscribers, please see links below and follow the instructions.

The accuracy and standardization of crossmatch results between different centers are essential in organ transplantation and the PT survey for XM-ONE serves as an important function in accomplishing this goal. We look forward to having your laboratory participate in these biannual external Olerup XM-ONE exercises.

If you should have any questions regarding registration, subscription payments, etc. please contact Eileen Tully below.
