The calibrated ELISA-based assay, which uses higher reference ranges and human MAG antigen rather than antigen sourced from other animal species, offers improved specificity in detecting antibody presence and increased diagnostic confidence.","thumbnail_url":"https://img.transistorcdn.com/jhRCftFebxnTMwoIbA_WoqrSKwFRD_Y2kbh0JDjhx14/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9lYjNj/ZDc0NTE0MWNlOWRl/YzRiN2Q3NDg2Mjg5/YWE4MS5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
