What is the correct method to mix blood in tubes containing anticoagulants?

When blood is collected into tubes with anticoagulants, the additive must be evenly distributed to prevent clotting and ensure accurate test results. The proper method is to gently invert the tube the number of times specified by the manufacturer. This gentle inversion mixes the blood with the anticoagulant without causing damage to the cells. Vigorous shaking can cause hemolysis and other damage, which can alter test results. Rolling the tube between the palms isn’t the standard technique for these tubes, and not mixing at all leaves the additive unmixed, risking clotting or improper sample performance. Always follow the tube’s instructions for the exact inversion count.
