Why do they shake blood samples?

Shaking the vials ensures that the chemicals are well mixed with the sample. We shake some samples to mix it with the solution in the bottom of the tube, generally an anticoagulant to prevent it from clotting. If the sample isn’t being mixed with anything we invert it gently to prevent clotting.

After the needle is inserted, a small amount of blood will be collected into a test tube or vial.
