Description

Indications: Solid organ transplant.

      Test Information: The purpose of this test is to monitor patients after transplant for the presence and level of antibodies to the donor’s HLA antigens. The test is semi-quantitative.

        Ordering Guidance (Protocol): This code is appropriate for DSA monitoring performed as part of a set protocol. Results will be available 6 business days after sample receipt. If a shorter turnaround time is required, order HLA Antibody Monitoring DSA, Routine (Sendout) [RHLAM] or HLA Antibody Monitoring DSA, STAT (Sendout) [RHLASM], as appropriate.
