Transportation of Samples

According to the Greek and European legislation, and the guidelines on sample transportation procedures for human samples of ISO 15189

Labnet SA, in collaboration with certified transporters, in order to ensure quality during the pre-analytical stage and the reliability of the results, ensures the safe and appropriate transport of samples from the partner laboratories to Labnet, applying all the specifications as defined by Greek (ADR REGULATION, FEK 509/2000, FEK 1350/2000), European legislation (94/55/EC) and the regulations for the transport of biological samples based on the ISO 15189 standard.

Vehicles with a special licence are used for the transport of biological materials in certified transport packages (UN3373 marking). Certified thermometer data loggers are used during transport, which record the temperature in order to monitor and ensure the appropriate conditions for the transport of the samples.

Biological samples are recommended to be centrifuged, separated and stored accordingly (refrigerated or frozen) before transported to Labnet laboratories. Samples are sent to the laboratory in special transport boxes (VTC), at the bottom of which an ice pack is placed to maintain the temperature at the desired level. It is recommended that direct contact of the samples with the ice packs be avoided. For this purpose, special receptors of the samples are mediated. Exam request forms should be placed in a slide or envelope separate from the samples. The samples are transported in special boxes – packages (Vacuette Transport Container, VTC, biological substance category B) according to the guidelines of the World Health Organization. The transport boxes (VTC) are provided by Labnet SA laboratories free of charge.

Typical times to ensure the stability of the samples are shown in the table below:

Typical sample storage times18-25 oC4-8 oC-20 oC
Serum6h24h10d
Serum (Glucose)10 min2h1d
Plasma (EDTA, Heparin, Citrate)2hNO10d
Whole Blood (Blood Count Test)8hNONO

After the requested tests have been performed, the samples are stored for ten days in dedicated sample storage areas in order to satisfy the collaborating laboratories’ demand for additional or duplicate tests.
