Reflex Testing
When the DAT is positive using polyspecific anti-human globulin, a DAT workup is performed and billed (CPT: 86880×4) using monospecific reagents (anti-IgG and anti-Complement). If the DAT workup indicates that the DAT is positive due to the anti-IgG.
An elution procedure is performed and billed (CPT’s: 86860, 86870) on the IgG positive cells to determine antibody specificity.
