Background:

the peripheral blood extension or peripheral lamina, as it is also known, is the semi-quantitative morphological evaluation of the three hematopoietic series, in an extension of peripheral blood colored and observed through the microscope.

Objective:

to develop a methodological procedure for the extension of peripheral blood from an interdisciplinary perspective in the degree in Clinical Bioanalysis.

Methods:

cross-sectional descriptive study in the period from September to November 2018, in the Technological Faculty belonging to the University of Medical Sciences of Camagüey. Theoretical methods such as analysis and synthesis and inductive and deductive methods were used. Of the empirical methods, the analysis of documents, the exploratory diagnostic test, results of controls to classes, the interview and survey for the validation of the proposal were applied.

Results:

insufficiencies regarding the establishment of interdisciplinary relationships between the contents of Histology and the hematological component of the Laboratory Diagnostic subject I, the students showed difficulties in performing the technique and failed to characterize morphologically some of the hematopoietic cells.

Conclusions:

a methodological procedure was developed for the peripheral lamina technique from an interdisciplinary perspective and the validation of the proposal by means of the consensus method formed by a nominal group where the categories of very adequate and suitable for the development of the peripheral lamina technique result. The observation of extension peripherals is an important element in the orientation of the analysis of the different diseases, an essential component of the integral diagnosis of the clinical laboratory.
