| Description
| - Aims: Platelet function testing is often affected by the existence of different pre-analytical variables that can cause platelet activation. The aim of this study was to assess the effect of such variables that are present when samples are taken (different anticoagulants, incubation temperature, and storage conditions) to select those which enable to reach optimal range of measured plasma concentrations of the two stable thromboxane A2 metabolites, that is, thromboxane B2 (TxB2) and 11-dehydrothromboxane B2 (11-dTxB2). Materials and Methods: For the purpose of this study, whole blood samples obtained from 20 volunteers were screened for TxB2 and 11-dTxB2 concentrations using commercial EIA kits (Cayman Chemicals; Neogen) in relation to the effect of different anticoagulants, using different incubation temperatures and storage conditions. Results:Trisodium citrate has been shown not to be affecting the TxB2 and 11-dTxB2 concentrations compared with the values measured in the serum. Incubation of the samples for 1 h at 37 °C and freezing at -20 °C or -80 °C give the most suitable concentration range of both thromboxanes in the used EIA measurement. Conclusion: This study describes the setup of such pre-analytical phase conditions that enable the screening of platelet function in terms of the plasma concentrations of TxB2 and 11-dTxB2 in selected EIA measurement.
