Anti-Xa levels should be collected 4 hours post dose or anytime on continuous infusion. Specimens must be stored at room temperature and transported to the Lab ASAP. Maximum delay to testing laboratory must not exceed 1hr.
2 mL Vacuette tubes should not be used for antiXa assays. The increased air space in the tube causes increased activation of the platelets and their subsequent release of platelet factor 4 results in neutralisation of the heparin. This can lead to an underestimation of the anti Xa level.
Please ask the patient what anticoagulants they are on and the dose, record on request form. Another name for Orgaran is Danaparoid.
