Investigation of thyroglobulin antibody assay discordance

Pickett Alan , Jones Meinir , Evans Carol

Measurement of anti-thyroglobulin (TgAb) predicts interference in thyroblobulin (Tg) assays and is a tumour marker for differentiated thyroid cancer (dtc). However, there is poor concordance between methods. This is attributed to the nature of TgAb, the method and cut-off used. We have assessed concordance between three TgAb assays and investigated the cause of discordant results. TgAb was measured in sera from 606 different patients being treated for dtc using the Abbott Arch...
