Test Overview
Test Methodology

Solid Phase Antibody Screening

Test Usage

HLA Antibody Specificity is used when the identification of HLA antibodies is needed after a screen detects the presence of HLA antibodies. The high specificity and sensitivity of this solid phase single antigen assay allows us to detect and identify low-levels of precise antibodies. The detection of antibodies in pre-transplant evaluation is an excellent tool for risk assessment and crossmatch prediction (Virtual Crossmatch and CPRA).
