Citrate Samples: Samples should be double spun and separated and frozen within 6 hours of sample taking. If a delay is expected with transportation to the laboratory, samples must be transported as frozen.

Note: The Lupus Anticoagulation test is not appropriate when a patient is on anticoagulation therapy. Suggest testing when the patient is cleared of anticoagulation or, selecting the Taipan Snake Venom test for lupus anticoagulant assessment if the patient is on oral anticoagulation.
