Rubric Error in the Cytology Laboratory Slide Substitution During Biopsy Examination In one pathomorphology center, a laboratory assistant accidentally mixed up the labeling of microscope slides. As a result, the patient received a false-positive diagnosis of “malignant tumor.” She underwent unnecessary surgical intervention before the error was discovered during a second consultation at another institution. ❓ How can the risk of sample substitution be reduced in cytological/histological practice?
