    Laboratory tests are essential for the diagnosis, prognosis, and monitoring of various diseases. The laboratory process includes three phases: pre-analytical (obtaining the biological material), analytical (performing the analyses), and post-analytical (issuing the report). Laboratory errors can occur at any stage, from the medical request to the interpretation of results, potentially leading to incorrect diagnoses or inadequate clinical interpretations. Most errors occur in the pre-analytical phase (46% to 68%) and post-analytical phase (19% to 47%). Objective: To investigate the main errors committed in the analytical phase and analyze their impact on post-analytical results. Methods: Data will be collected from books and scientific articles on the PubMed and Scielo platforms. The analysis will include reading abstracts and, subsequently, the full texts of the most relevant articles. Development: The review identified the main errors in the analytical phase, such as inadequate calibration of equipment, lack of internal controls, incorrect sample identification, cross-contamination between samples, loss or exchange of samples, unvalidated analytical systems, quality control failures, pressure for quick results, and instrument malfunctions. These errors are often caused by human failures. It is crucial for clinical laboratories to ensure the correct execution of all stages to avoid errors in the results. Conclusion: Each phase of the laboratory process is crucial, as errors at any stage can compromise test results. The literature review showed that the most frequent errors in the analytical phase are inadequate equipment calibration and lack of internal control. Technological advancements and automation have helped reduce errors and improve the quality of tests.
