Red Top
Additive: None

Mode of Action: Blood clots, and the serum is seperated by centrifugation

Uses: Chemistries, Immunology and Serology, Blood Bank (crossmatch)
Gold Top
Additive: None

Mode of Action: Serum separator tube (SST) contains a gel at the bottom to separate blod from serum on centrifugation

Uses: Chemistries, Immunology and Serology
Light Green Top
Additive: Plasma Separating Tube (PST) with Lithium Heparin

Mode of Action: Anticoagulates with lithium heparin; lasma is separated with PST get at the bottom of the tube.

Uses: Chemistries
Purple Top
Additive: EDTA

Mode of Action: Forms calcium salts to remove calcium

Uses: Hematology (CBC) and Blood Bank (Crossmatch); requires FULL DRAW-invert 8 times to prevent clotting and platelet clumping.
Light Blue Top
Additive: Sodium Citrate

Mode of action: Forms calcium salts to remove calcium

Uses: Coagulation tests (protime and prothrombin time), FULL DRAW required.
Green Top
Additive: Sodium heparin or lithium heparin

Mode of Action: Inactivates thrombin and thromboplastin

Uses: For lithium level, use sodium heparin. For ammonia level, use sodium or lithium heparin.
Dark Blue Top
Additive: Sodium EDTA

Mode of Action: Tube is designed to contain no contaminating metals.

Uses: Trace element testing (zinc, copper, lead, mercury) and toxicology.
Light Gray Top
Additive: Sodium flouride and potassium oxalate

Mode of Action: Antiglycolytic agent preserves glucose up to 5 days

Uses: For lithium level, use sodium heparin. Glucoses require FULL DRAW (may cause hemolysis if short draw)
Yellow Top
Additive: ACD (acid-citrate-dextrose)

Mode of action: Complement inactivation.

Uses: HLA tissue typing, paternity testing, DNA studies
Yellow-Black Top
Additive: Broth mixture

Mode of action: Preserves viability of microorganisms.

Uses: Microbiology-aerobes, aneaerobes, fungi
Black Top
Additive: Sodium citrate (buffered)

Mode of action: Forms calcium salts to remove calcium

Uses: Westergren Sedimentation Rate; requires FULL DRAW
Orange Top
Additive: Thrombin

Mode of Action: Quickly clots blood

Uses: STAT serum chemistries
Light Brown Top
Additive Sodium heparin

Mode of Action: Inactivates thrombin and thromboplastin; Contains virtually no lead.

Uses: Serum Lead determination
Pink Top
Additive: Potassium EDTA

Mode of Action: Forms calcium salts

Uses: Molecular/viral load testing
