ABSTRACT
It is basic that in the study of patients with pathology of the low genital tract strictly gets applied the quality control, with the purpose of reducing anxiety in patients with minor results or false positives and to establish opportune treatments in patients with major injuries. Esteem that the rates of false negatives in studies of Papanicolaou go from 6 to 50%. The three fundamental aspects to have better results are: 1.- Taking of the sample; 2.- Preparation and 3.- Lecture.
The colposcopy study must be done by enabled personnel, having cito-colpo histology corelation of at least 80%, making treatments based on standards and guides of handling based on 014 NOM and International Federation of Cervical Colposcopy and Pathology of the Inferior Genital Tract and to at least make pursuit of 90% of the patients.
The histopatology study gets to have from 1 to 43% of failure and this can happen in any of the 5 phases: 1.- Pre-pre-analytical: Suitable selection of the study. 2.- Pre-analytical: Identification, preparation and transportation of the sample; 3.- Analytical: Preparation and interpretation of the study. 4.- Post-analytical: Opportune report of the result, copy file and storage of the material. 5.- Post-post-analytical: Treatment based on the result.
