The film was returned to the manufacturer for processing and then interpreted by a single cervicography-certified gynecological oncologist as follows: negative if normal; atypical if there was evidence of an acetowhite lesion of doubtful significance either inside or outside the transformation zone or if there was evidence of atypical immature squamous metaplasia; positive if there was evidence of a minor-or major-grade lesion or cancer; and technically defective if the film was technically uninterpretable.
