The effects of transport by pneumatic tube system on urine analysis

Abstract

The pneumatic tube transport system (PTS) is used frequently for the transport of samples in hospitals. Effects of PTS on urine components are unknown. In our study, we aim to examine the influence of PTS on the quality of routine urine microscopic parameters. Urine samples were divided into two groups: group 1 were transported to the laboratory manually and group 2 were transported to the laboratory via the PTS. Each of 187 urine samples was studied with iQ200 automated urine devices for erythrocytes, leukocytes, epithelial cells, crystal, cast and yeast cells. No statistically significant differences were detected between group 1 and group 2 for urine parameters. For erythrocytes, leukocytes, and epithelial cells, the gamma was 0.982, 0.959, and 1.0, respectively. For crystal, cast and yeast cells, the kappa values were 0.952, 0.866, and 1.0, respectively. PTS has no effect on erythrocytes, leukocytes, epithelial cells, crystal, cast, and yeast cells in urine analysis. We concluded that PTS can be used in the transport of urine samples.
