关键字：Background: The single-specimen pneumatic tube (PTS) is a commonly used rapid specimen delivery system in modern clinical laboratories. However, its impact on sample integrity and laboratory test results remains controversial. The installation and configuration of single-specimen PTS are unique to their institution. We sought to validate our single-specimen PTS by comparing routine chemistry, immunology, and hematology results with a repeat sample integrity index for manual transport. Methods: In 2023, 30 employees were randomly selected from the company medical examination, and three tubes of procoagulant serum samples and three tubes of EDTA anticoagulant blood samples were collected from each of them. Group A uses a single specimen PTS at 8 m/s, Group B uses a single specimen PTS at 15 m/s, and Group C uses manual transfer. Specimens from all three groups were simultaneously analysed for ALT, AST, TG, TC, LDL, K, NA, CI, TSH, hs-cTnT, NSE, Cyfra21-1 and haematological analysis. Results: The differences between the three groups of NSE and Cyfra21-1 were statistically significant (P < 0.05). The differences of the rest of the items were not statistically significant. The difference in NSE was not statistically significant between groups A and B (P = 0.401), B and C, and C and A (P < 0.05). The difference in Cyfra21-1 was not statistically significant between groups A and B (P = 0.897), B and C (P = 0.052), and C and A (P = 0.145). Conclusion: Individual sample PTS should be validated for testing prior to use to ensure the results’accuracy.
