Therapeutic turnaround time (TAT) and process traceability are critical issues for First Aid laboratory tests. There is a wide variability in pre-analytical activities from blood sampling to laboratory arrival. The report evaluates the improvement of TAT after activation of the Tempus600® system, its impact on the organization of the Emergency Room and on the integrity of blood samples.

Background: The Department of Clinical Immunology and Biochemistry, Lillebaelt Hospital, Denmark, and TIMEDICO invented and developed the Tempus600®, a pneumatic tube system (PTS). This system is only 2.5 cm in diameter and sends blood tubes directly, without packing before transport. Request forms need not be enclosed, since samples are labeled with patient and barcode ID. At the end of the pipes, a robot receives and places the tubes onto a good laboratory practice (GLP) transport system after the principle of “first in, first out” (FIFO), whereafter the tubes are delivered to centrifuges and analytical equipment. The whole system has decreased the total turnaround time (ToTAT) from 2 to 3 h to <60 min. The aim of the study was to validate the Tempus600/GLP robot system for the 89 most frequent or critical components.
Methods: Two sets of blood samples were drawn from 100 patients. One set was sent by the Tempus600/GLP robot system, and the other was couriered directly to the laboratory for analysis. Results were compared using difference plots.
Results: The results for 85 of the components did not deviate from the optimized fast courier reference transport more than could be expected by the analytical variation. O2 saturation, oxyhemoglobin, and partial pressure of oxygen (PO2) deviated considerably from a clinical point of view. Partial pressure of carbon dioxide (PCO2) results were clinically acceptable for assessing patients with obstructive lung disease for hypercapnia.
Conclusions: The Tempus600/GLP robot system can be used for transport of the majority of routinely used analytical tests.

During transport, a mini data logger recorded the accelerations in three dimensions and reported them in arbitrary area under the curve (AUC) units. In addition representative quantities of clinical chemistry, hematology and coagulation were measured and compared in 20 blood sample pairs transported by Tempus 600® and courier.
Samples transported by Tempus 600® were brought to the laboratory (300 m) within 30 s without adverse effects on the samples. The information retrieved from the data logger showed a median AUC of 7 and 310 arbitrary units for courier and Tempus 600® transport, respectively. This is considerably below the reported limit for noticeable hemolysis of 500 arbitrary units.
Tempus 600® reduces TAT by reducing the hands-on time and a fast transport. No differences in the measurement results were found for any of the investigated 36 analytes between courier and Tempus 600® transport. Based on these findings the Tempus 600® was cleared for clinical use in our hospital.
This validation report was conducted at the UMCG Groningen, Netherlands.
The report describes the validation of transport via the pneumatic dispatch system and the Tempus 600 system. For determined test values, the differences between the methods of transport fall within the analytical variation and the Tempus600 system was approved for transport of vacuum tubes.
The further details can be found in report.
A poster presentation concerning the stability of biochemical components in blood samples showed that the Tempus600®/GLP robot reception system can be used for transport of the majority of routinely used analytical test. The test was conducted at Lillebælt Hospital, Denmark. 100 patients from the hospitals outpatient clinic were included in the test.
With the use of mini data loggers the quality of samples were measured sending samples with TEMPUS600.
Acceleration forces acting on samples showed not to impact the analytical results. The overall workflow were improved considerably by decreasing hands on time on the ward and in the laboratory.
Findings and results presented at DGKL, 24. – 27. September 2014 in Congress Center Rosengarten, Mannheim, Germany.
A newly conducted study showed that the implementation of TEMPUS600 ensures reduced turn-around-time for laboratory results and hereby faster patient treatment. The study showed that a dedicated single tube transport system of TEMPUS600 reduces time from sampling to ready results from an average of 85 to 48 minutes.
The findings were published at the NFKK 2014 on 16-19 September in Gothenburg, Sweden.
