Background. Automation helps improve laboratory operational efficiency and reduce the turnaround time. Pneumatic tube systems (PTS) automate specimen transport between the lab and other areas of the hospital. Its effect on complete blood count (CBC) and coagulation is still controversial.Aim. To study the effects of pneumatic tube system sample transport on complete blood count and coagulation parameters to compare them with hand delivered samples.Methods. 75 paired samples for complete blood count and 25 paired samples for coagulation analysis were compared between samples sent via pneumatic tube system and hand delivered system.Results. PTS showed significant decrease in red cell indices such as MCV and RDW and increase in MCHC. Other red cell parameters and WBC parameters showed no statistical significant difference. Statistically significant increase in platelet count was observed with PTS samples. However, these differences were clinically insignificant. No significant effect of PTS was found in PT and APTT samples compared to the hand delivered samples.Conclusion. Despite statistically significant changes in RBC parameters such as MCV, RDW, and MCHC and platelet count, these changes were clinically insignificant. Hence, blood samples for CBC and coagulation assay can safely be transported via our hospital’s PTS. However, further studies on platelet count are warranted to ensure safe transport and accuracy of the results.

Pneumatic Tube System

The transportation of laboratorial samples with pneumatic tube system spends less time than when were handled by courier.Pneumatic tube system produces minor vibrations on sample due to the velocity changes during transportation and may cause changeson the blood cells and haemolysis. The aim of this study is to know the effect of sample transportation with pneumatic tube on bloodcells and its effect on hemolysis. A cross sectional study was performed at Dr. Wahidin Sudirohusodo Hospital, Makassar in July 2013.Routine blood, electrolyte and LDH were tested in 12 out-patients. The researchers collected two (2) samples, for each EDTA tube (routineblood tests) and serum (electrolyte and LDH). The samples were transported using pneumatic tube and the paired samples were sentby courier. The result then were analyzed with Paired T-Test. There were no significant difference of routine blood test results betweensamples sent by pneumatic tube and courier except RDW. RDW were higher in samples which were sent by pneumatic tube comparedto those brought by the courier (18.72±2.70% vs 17.83±2.36%, p=0.007). The electrolyte levels sent by both methods there were nosignificant difference, but the LDH levels were higher in samples sent by pneumatic tube (472.08±100.44 U/L vs 331.25±94.19 U/L,p=0.000). Based on this study, in common can be concluded that the pneumatic tube system does not effect on the routine blood testresults, except on RDW and does not cause changes due to haemolysis (on electrolyte) except the LDH levels elevates. So based on thisstudy, it is recommended to send samples for LDH test only by courier.

Abstract Background Timely blood delivery to patients with critical bleeding poses logistic challenges. A modern, high speed hospital pneumatic tube system (PTS) is one solution, but blood units may be subjected to high-speed torque and acceleration/deceleration forces. Objective To validate a new PTS system for potential use at our 1,400-bed hospital in Singapore. Method Our validation included red blood cells, platelets, thawed plasma, and cryoprecipitate units transported from the blood bank for a distance of 820 meters (PTS track), at a velocity of 3–6 meters per second. Transit time, temperature, bag integrity, and blood quality were assessed visually and through analytical testing on pre- and post-PTS specimens. Results Blood units arrived physically intact in less than 8 minutes. The temperature for each was within the acceptable range. Comparative testing of pre-PTS and post-PTS specimens showed no significant difference in physical quality and analyzed parameters (P> .05). Conclusions High speed PTS transportation of blood components has satisfactory fidelity and speed, without significant impact on quality. As a result, we incorporated PTS blood delivery into the hospital massive-transfusion protocol and successfully operationalized that new system.

There have been few studies reported with conflicting results in the use of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), redcell-distribution-width (RDW), etc. for predicting prognosis and differential diagnosis of adrenal tumors. The aim of this study is to investigate the role of inflammatory markers through a complete blood count, which is an easy access low-cost method, for the differential diagnosis of adrenocortical adenoma (ACA), adrenocortical carcinoma (ACC), and pheochromocytoma. The data of patients who underwent adrenalectomy between the years of 2010–2020 were retrospectively analyzed. Systemic hematologic inflammatory markers based on a complete blood count such as neutrophil ratio (NR), lymphocyte ratio (LR), NLR, PLR, RDW, mean platelet volume (MPV), and maximum tumor diameter (MTD) were compared between the groups. A statistically significant difference was found between the three groups in terms of PLR, RDW, and MTD. With post-hoc tests, a statistically significant difference was found in PLR and MTD between the ACA and ACC groups. A statistically significant difference was found between the ACA and pheochromocytoma groups in PLR and RDW values. In conclusion, it could be possible to plan a more accurate medical and surgical approach using PLR and RDW, which are easily calculated through an easy access low-cost method such as a complete blood count, together with MTD in the differential diagnosis of ACC, ACA, and pheochromocytoma.
