Life Code Transplant

LIFECODES is a world-class leader in transplant diagnostics providing a broad portfolio of molecular and antibody-based assays using ELISA and xMAP® technology to evaluate HLA compatibility between donors and recipients.

Laboratories all over the world use LIFECODES HLA serology and molecular typing assays as part of determining the best path forward for a transplant recipient. The more compatible the donor-recipient match, the less likely for organ or stem cell rejection.
