Table 5.
Recovery rate of the AFB1 in serum after spiking of AFB₁ (ng/mL)

Concentration (ppb)1)	Absorbance (405 nm)	Detected concentration (ppb)	Recovery rate (%)
10	0.418 0.036	7.629	76
50	0.256 0.052	44.212	84
100	0.138 0.054	91.094	91

The standard curve originated in 0.5~500 ng/mL concentration of AFB₁ standard and represent means duplicate trials.
