A series of trials were conducted to evaluate Brix refractometry (Brix%) for the assessment of failure of passive transfer (FPT) in dairy calves compared to (1) serum IgG (reference standard) when measured by radial immunodiffusion (RID) or a turbidometric immunoassay (TIA), and (2) to serum total protein refractometry (STP).
