What is in a tiger top blood collection tube?

This tube is used for preparing EDTA plasma, whole blood, and bone marrow specimens. This tube is used for collecting serum or clotted whole blood specimens. Tiger-top tube (serum separator): Tube does not contain an anticoagulant but does contain a clot activator and serum separator gel.
  • What is a clot activator tube?

    A special coating on the internal wall of the tubes containing microscopic silica particles activates clotting. VACUETTE® Z Serum Sep Clot Activator tubes contain an inert separator gel on the base of the tube which, after centrifugation, forms a stable barrier between the serum and the blood clot.

What is in a tiger top tube?

Gold or red/gray tube, also known as a tiger tube that contains a clot activator. It is used to separate blood from the serum. Tubes with a red stopper are used to collect serum to test for routine donor screening or infectious disease. It contains a clot activator.
  • How do you separate plasma from blood?

    After collection of the whole blood, allow the blood to clot by leaving it undisturbed at room temperature. This usually takes 15–30 minutes. Remove the clot by centrifuging at 1,000–2,000 x g for 10 minutes in a refrigerated centrifuge. The resulting supernatant is designated serum.
