[Bacteriological evaluation of a new system for transport and storage of urine: the UC and S Vacutainer system]

A study realized on 360 clinical urine specimens compared results of the cytobacteriological examination obtained from freshly voided urines and from the same urines preserved during 24 hours at room temperature (20-22 degrees). A new system (UC & S Vacutainer system--Becton-Dickinson) was used for preservation. Urine preservation induced no change in count of leukocytes and erythrocytes present in urine and in bacterial count (agreement between the two numerations: 98.8 p. cent). Bacterial identification and determination of antibacterial activity of antibiotics remained also unchanged. Soluble antigens eventually present in urine were not altered by preservation on UC & S tubes. This study showed that UC & S Vacutainer system was very effective for preservation of urine clinical specimens.
