UNGER, Gisela; BENOZZI, Silvia Fabiana y PENNACCHIOTTI, Graciela Laura. Need to harmonize the pre-analytical phase of 24-hour urine: evidence from a survey. Acta bioquím. clín. latinoam. [online]. 2017, vol.51, n.4, pp.615-620. ISSN 0325-2957.
The objective of the present work was to evaluate the harmonization state of the pre-analytical phase of 24-hour urine. To this aim, an anonymous survey on the pre-analytical phase of 24-hour urine (Moreno-Carbonell, et. al) was carried out by biochemists from Argentina. A total of 92 professionals responded to the the survey. As a result, 95% provide patients with written instructions for collection; 11% include visual graphic instructions; 37% record starting and finishing time of collection; 59% recommend sample refrigeration during collection time; 73% supply the container; 47% provide the container with a preservative, if necessary; 100% ask the patient to take the complete 24-hour volume to the laboratory; 4% indicate to measure and record sample volume and to take an aliquot of it; and 78% perform one or more actions to evaluate the proper collection procedure. The rejection criteria selected in decreasing order were: loss of micturition, non-compliance with collection time, according to the volume and daily creatinine excretion, and improper container. To conclude with, this survey showed that there are aspects of the pre-analytical phase of 24-h urine that need improvement and harmonization between laboratories.
