Subject & method: 44 hospital employees, each staff was collected two blood samples in two heparin lithium tubes. The first blood sample was manually transported from the Outpatient Departurment to the Biochemistry Laboratory by a hospital staff for at least 15 minutes. The second sample was transported by the pneumatic tube system at a speed 12m/s, transport tube length 400m. The hemolysis index and some plasma chemistry tests including electrolytes, total Cancium, SGOT, SGPT, ALP, LDH, phosphorus, total Bilirubin, CK, total Protein, Albumin were performed on the blood samples and compared between the difference method of transports. Results: The hemolysis rate of blood samples which transported by the pneumatic system and manual transport were 6.83% (3/44) and 0%, respectively. This rate of hemolysis was statistically higher than the average annual hemolysis rate of the manual transport of Biochemistry Laboratory, Bạch Mai Hospital in two years 2022-2023 (p<
0.001). The mean of Plasma Lactat dehydrogenase of samples by the pneumatic system (198.34±37.5U/L) was statistically higher than by manually (168.4± 26.6 U/L) (p<
0.01) respectively and LDH (bias%: 19.1%) exceeded the total error allowable limit ≤ 15% (CLIA). Conclusion: Hemolysis of blood samples and plasma LDH levels increased by the transportation of the pneumatic tube system.
