GIL, Pamela; FRANCO, Micaela  y  GALBAN, Gustavo. Evaluation of preanalytical mistakes in the routine laboratory of HIGA O. Alende of Mar del Plata. Acta bioquím. clín. latinoam. [online]. 2016, vol.50, n.3, pp.463-468. ISSN 0325-2957.

The preanalytical phase involves all steps to be followed in chronological order until the start of the analytical procedure. The objectives of this study were to evaluate pre-analytical mistakes of the daily routine proceeds to the laboratory with at least one application involving sections of Clinical Chemistry and/or Hematology Hemostasis in HIGA O. Alende of Mar del Plata. They were defined as pre-analytical errors (EPA) any error in the application/ admission or extraction/collection of the sample. Were calculated the percentage of applications with one or more EPA, the frequency of each type of error, and the error distribution per service and day of week. Seven thousand and eight hundred and fifty applications were analyzed, of which 82% had one or more EPA. A total of 9141 errors were surveyed, with 91% errors in the application / admission of the sample. It was concluded that there are a large number of pre-analytical errors, of which the highest percentage is in the application / admission. Much of the hospital staff participates in the origin of these mistake; therefore it is important to sensitize them to achieve improved quality of laboratory results, essential for making medical decisions.
