OPN1SW and breast cancer: BCP-positive DISQVER results occur into four categories: 1) those confirmed by blood cultures (BC) collected on the same day (+/-24 hours); 2) those confirmed by BC collected earlier or later than DISQVER samples during that hospitalization; 3) those in which DISQVER pathogens were only found in other microbiological samples; and 4) those that could not be reconfirmed in routine diagnostics.
