Schober et al. demonstrated that when a mass accuracy window greater than ± 10 ppm is used, numerous peptides from different proteins with similar masses can be assigned to the incorrect protein [60]. This means that CA125 identification without supporting statistical analysis is unreliable and potentially false-positive."}
