The revised concentration of the Liquichek 3 control analytes in the test well as measured via the conventional ELISAs (mean ± SD). The standard spans points 1–7 of subsequent twofold dilutions with 8, a diluent only negative control, completing the set. AGP, alpha-1-acid glycoprotein; CRP, C-reactive protein; RBP, retinol binding protein 4; sTfR, soluble transferrin receptor.
