AbstractMany preanalytical variables may affect the results of routine coagulation assays. While advances in laboratory instrumentation have partially addressed the laboratory's ability to recognize some of these variables, there remains an increased reliance on laboratory personnel to recognize the three potential areas where coagulation testing preanalytical issues may arise: (1) specimen collection (including patient selection), (2) specimen transportation and stability, and (3) specimen processing and storage. The purpose of this article is to identify the preanalytical variables associated with coagulation-related testing and provide laboratory practice recommendations in an effort to improve the quality of coagulation testing and accuracy of result reporting.

Background: polytrauma is one of the emergency surgeries with a high mortality rate. One of the leading causes of death is coagulopathy that is not detected early and treated promptly. Thromboelastometry (ROTEM) is a whole blood assay that evaluates the viscoelastic properties during clot formation and clot lysis. This method can detect coagulopathy rapidly and accurately, thereby improving the management of bleeding after trauma. Objectives: describing and evaluating the correlation between ROTEM parameters and routine coagulation tests in polytrauma patients at admission. Method: 110 patients admitted to the Emergency Department, Viet Duc University Hospital from May 2021 to July 2021 were diagnosed with polytrauma. All patients underwent routine coagulation testing and ROTEM parameters at admission. Result: the average age of patients is 41.4±14.7 years old, men accounts for 77.3%, average ISS score is 24.5±6.3. The proportion of the polytrauma patients with coagulopathy by routine coagulation testing was 50.9%. A significant correlation was found between routine coagulation parameters and ROTEM: between APTT with CFT-INTEM (r=0.65; p<0.01); between PT and CFT-EXTEM (r=0.64; p<0.01); between platelet count and MCF-INTEM (r=0.56; p=0.00) and MCF-EXTEM (r=0.57; p=0.00); between fibrinogen level and MCF-INTEM (r=0.71; p=0.00), MCF-EXTEM (r=0.71; p=0.00), and MCF-FIBTEM (r=0.91; p=0.00). Conclusion: proportion of the polytrauma patients with coagulopathy by routine coagulation testing was 50.9%. A significant correlation was found between routine coagulation parameters and ROTEM

AbstractTo evaluate the effects of fructose diphosphate (FDP) on routine coagulation tests in vitro, we added FDP into the mixed normal plasma to obtain the final concentration of 0, 1, 2, 3, 4, 5, 6, 10, 15, 20, 25, 30 and 35 mg/mL of drug. Prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen (FBG) and thrombin time (TT) of samples were analyzed with blood coagulation analyzers from four different manufacturers(Sysmex, Stago, SEKISUI and Werfen) and their corresponding reagents, respectively. Before the experiment, we also observed whether there were significant differences in coagulation test results of different lots of reagents produced by each manufacturer. At the same time as the four routine clotting tests, the Sysmex blood coagulation analyzer and its proprietary analysis software were used to detect the change of maximum platelet aggregation rate in platelet-rich plasma after adding FDP (0, 1, 2, 3, 4, 5 and 6 mg/mL). The results of PT, aPTT and TT showed a FDP (0–35 mg/mL) concentration-dependent increase and a FBG concentration-dependent decrease. The degree of change (increase or decrease) varied depending on the assay system, with PT and aPTT being more affected by the Sysmex blood coagulation testing instrument reagent system and less affected by CEKISUI, TT less affected by CEKISUI and more affected by Stago, and FBG less affected by Stago and more affected by Sysmex. The results of PT, aPTT and TT were statistically positively correlated with their FDP concentrations, while FBG was negatively correlated. The correlation coefficients between FDP and the coagulation testing systems of Sysmex, Stago, Werfen and SEKISUI were 0.975, 0.988, 0.967, 0.986 for PT, and 0.993, 0.989, 0.990 and 0.962 for aPTT, 0.994, 0.960, 0.977 and 0.982 for TT, − 0.990, − 0.983, − 0.989 and − 0.954 for FBG, respectively. Different concentrations of FDP (0, 1, 2, 3, 4, 5 and 6 mg/mL) had different effects on the maximum aggregation rate of platelet induced by the agonists of adenosine diphosphate (ADP, 5 µmol/L), arachidonic acid (Ara, 1 mmol/L), collagen (Col, 2.5 µg/mL) and epinephrine (Epi,10 µmol/L), but the overall downward trend was consistent, that is, with the increase of FDP concentration, the platelet aggregation rate decreased significantly. Our experimental study demonstrated a possible effect of FDP on the assays of coagulation and Platelet aggregation, which may arise because the drug interferes with the coagulation and platelet aggregation detection system, or it may affect our in vivo coagulation system and Platelet aggregation function, the real mechanism of which remains to be further verified and studied.
