Preferred Specimen
1 - 4.5 mL completely filled glass Sodium (Na) Citrated (light blue top) tubes.
Instructions
Light blue top tube, completely filled. Avoid hemolysis, gently invert 10 times. Specimen must remain at room temperature and do NOT centrifuge. Care must be taken that sample if free flowing, ie not a difficult draw due to the potential to clump the platelets. If the platelets have clumped, the test will be cancelled. Testing must be completed within 4 hours of collection and dispatch should be called with draw time to allow arrangement of timely transportation.
