Abstract

Introduction: The pre-analytical phase is an essential component in the clinical analysis algorithm, which entails a series of steps and procedures. Objective: To describe the level of compliance with pre-analytical indicators in the chemistry and hematology areas of the clinical laboratory of the Inmaculada Concepción District Hospital. Materials and methods: A non-experimental design was applied with a mixed cross-sectional approach and descriptive scope. Three biochemists and one hundred patients were included through convenience sampling. Data were obtained through structured patient observation and semi-structured interviews with hospital staff. Results: The level of performance of biochemists in relation to pre-analytical indicators presents both positive and negative aspects, of which the positive aspect stands out at 61% and 39% corresponds to aspects considered deficient. The existing difficulties are the correct identification of the patient and the communication between the attending physician and/or technician with them, most of whom are unaware of the conditions under which they should present themselves for a medical examination. Conclusion: The proper implementation of the correct actions, as well as their quality, in the pre-analytical phase is directly related to the results obtained, which will then be used by the requesting professionals for decision-making. Therefore, it is an initial link that affects the entire subsequent process.
