• 3088-00 or*3088-02 (STAT) – Lymphocyte Crossmatch

HLA Antibody Specificity Monitoring DSA (Donor Specific Antibody) is performed with recipient’s post transplant serum. Antibodies to donor antigens are evaluated and monitored. Additional post transplant tests C1q, MICA,and  AT1R can also be performed using the recipients post transplant serum.  Lymphocyte crossmatches may also be performed using donor cells and recipient’s post transplant serum.
