All three thyroglobulin immunoassays showed strong overall correlations, but discrepancies were noted at lower and higher Tg levels.
Tg-L demonstrated a strong correlation with Tg-B at ρ = 0.89, while Tg-A showed an even better correlation at ρ = 0.92.
Concordance rates for detecting undetectable Tg were 96% for Tg-L and 98% for Tg-A compared to Tg-B.
The findings suggest a need for re-baselining when switching immunoassays in clinical follow-up, emphasizing the importance of assay characteristics.
