BACKGROUND-AIM Time between a specimen is received within the laboratory and the result is available (TAT) is a quality laboratory index, which affects diagnosis and treatment. It is defined as the interval between the arrival time of a sample to the laboratory and clinical validation. The aim of this study was to evaluate the TAT for stat analytical biochemistry, studying the workflow in preanalytical, analytical, postanalytical and total phases, in order to plan possible actions to improve

TAT was collected (in minutes) for each period and phase. Dates were processed with Excel 2010. RESULTS We processed 23, 61 and 57 samples during periods 1, 2 and 3, respectively. The average number of test per sample was eight: glucose, urea, creatinine, sodium, potassium and chloride, 19% of the samples were measure these six test, and 96% of stat requests included these test studied. The average TAT was 26, 19, 12 and 57 minutes for the preanalytical, analytical, postanalytical and total phases, respectively. For periods 1, 2 and 3 the average total TAT was 61, 59 and 53 minutes, respectively. CONCLUSION During the periods when our stat samples were measure at the same time that hospitalization samples (8-10h) and Primary Health Care samples (10-12h), the total TAT was higher, mostly due to the time spent in the preanalytical phase. We have to analyse which factors influence this phase and prioritize urgent samples in order to adapt to health care needs.
