Test Overview
Test Methodology

HLA Class II Low Resolution HLA typing is achieved via the reverse SSO method that utilizes a suspension array platform using microspheres as a solid support to immobilize oligonucleotide probes. The target DNA is amplified by polymerase chain reactions (PCR) and then hybridized with the bead probe array.

Test Usage

Testing of HLA Class II antigens, DRB1, DRB345, DQB1, and DPB1. This test can be ordered to supplement historic solid organ transplant typings that are incomplete, or for disease associations for any of the Class II antigens.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
