Given the following data for bichromatic analysis in which the analytical wavelength is 510 nm, what is the most likely interference?
Patient sample absorbance at 510 nm = 0.715
Patient sample absorbance at 550 nm = 0.113
Standard absorbance at 510 nm = 0.500
Standard absorbance at 550 nm = 0.113
Standard concentration = 25 mg/L
