Blood Collection Tubes

How do red tiger top, or gold serum separator tubes work, and what coagulant or anticoagulant is typically found in them?

• They contain a gel that separates serum from blood cells; they typically contain dry silica particles to promote clotting.

• They contain gel to hemolyze any red cells, and EDTA as an anticoagulant to prevent clotting.

• They contain gel to separate serum from blood cells, and heparin as an anticoagulant to prevent clotting.

What is the primary function of a light blue-top blood collection tube, and what type of coagulant or anticoagulant is present in it?

• To separate plasma from blood cells; no coagulant or anticoagulant is present.

• To promote coagulation for clot formation; it contains EDTA.

• To allow intact plasma collection; it contains sodium citrate.

Which clinical laboratory department is most likely to utilize red-top tubes for specimen processing?

• Hematology

• Chemistry

• Microbiology

Can you explain the purpose of using a lavender-top blood collection tube, and what anticoagulant is typically found in this type of tube?

• To prevent clotting; it contains EDTA as an anticoagulant.

• To promote coagulation; it contains heparin as a coagulant.

• To separate plasma; it is typically coagulant-free.

In which department of the clinical laboratory is the lavender-top tube most commonly used?

• Microbiology

• Hematology

• Hemostasis/Coagulation

How does a green-top blood collection tube function, and what type of anticoagulant is typically found in it?

• It promotes clotting; it contains no additive.

• It separates plasma from blood cells; it is typically coagulant-free.

• It preserves plasma; it contains heparin as an anticoagulant.
