Recently the French Society of Anaesthesia and Intensive Care issued recommendations for the prescription of routine preoperative testing before a surgical or non-surgical procedure, requiring any type of anaesthesia [ 9 ]. The required ratio of sodium citrate to whole blood is [ 3549 ]. Before blood sampling, the disturbing influences of food and drink should be excluded. Guder WG. J Thromb Haemost. Relationship between ABO blood group and von Willebrand factor levels: from biology to clinical implications. For specialized coagulation testing, most samples are sent as frozen samples, whilst samples for routine coagulation are more often sent as citrated blood primary tube. Blood sampling According to the recommendations of the EFLM, tube labelling must be done, before or after venipuncture, in the presence of the patient. These tubes allow for more reliable measurement of unfractionated heparin UFH and are useful for the study of membrane glycoproteins platelet by flow cytometry.

    Even if the ISTH-BAT has not been evaluated sufficiently in inherited platelet function disorders to allow a firm recommendation of its use, it could also be potentially useful for the diagnosis of platelet function disorders [ 3233 ].

    Blood sampling should be performed without generating foam or bubbles in the sample and with as little shear stress as possible [ 4 ]. Five-minute preparation of platelet-poor plasma for routine coagulation testing.

    Other BS have been developed for the large population of patients with atrial fibrillation AF that require oral anticoagulant therapy e. Temperature control is recommended in rooms where samples are kept for analysis [ 2 ]. Diet and drinking are major factors influencing a number of analyses.

    Preanalytical issues in the haemostasis laboratory guidance for the clinical laboratories

    For the Platelet Function Analyser PFAwhich replaces the bleeding time in many laboratories, the lower shear stress generated by manual aspiration of blood into the primary collection tube would prevent spurious hyper-activation of platelets, thus, preserving the integrity of their function for subsequent testing on PFA [ 82751 ].

    The overall fibrinolytic activity is impaired during pregnancy, but returns rapidly to normal following delivery.

    Antecedents of anemia, iron supplementation, hospitalization or blood transfusion can also guide the clinician [ 1112 ]. Contamination of coagulation assay tubes is possible if coagulation tubes are drawn following an additive tube like certain serum collection tubes containing clot activators [ 36 ]. Ten Cate.

    Freeze-thawing may produce phospholipid rich membrane microvesicles from platelet damage which may then mask the presence of a lupus anti-coagulant [ 89 ]. We are hearing a lot about multidisciplinary care and implementing this practically in patients who are older who have cancer.

    There are no data to support the need for a discard tube for specialized haemostasis assays [ 5 ]. To collect the bleeding history, in case of haemorrhagic diathesis or preoperative assessment of bleeding risk, and to obtain the resulting bleeding score BSstandardized and validated clinical tools are necessary [ 10 ]. A discard tube or a citrate tube if the sampling is difficult must be drawn when citrated plasma is obtained using butterfly systems or other IV catheter devices because the air volume contained in the tubing partially fills the vacuum tube, leading to insufficient filling of the tube with citrate.

    The pH of the anticoagulated plasma should be comprised between 7. Under-filling increases the dilution of the sample due to the volume of liquid anticoagulant, and may increase the clotting time due to the excess calcium-binding citrate present [ 4547 ].
