Anti-reference ability of the immunoassay (The error bars are standard deviations for n = 3). The concentrations of IgG, AA, UA, glucose, CEA, PSA, NSE and AFP were 10 ng mL−1. The mixture contains IgG (10 ng mL−1), AA (10 ng mL−1), UA (10 ng mL−1), glucose (10 ng mL−1), CEA (10 ng mL−1), PSA (10 ng mL−1), NSE (10 ng mL−1) AFP (10 ng mL−1), and CYFRA21-1 (0.5 ng mL−1).
