Question | Uses | Additive | Mode Of Action |
---|---|---|---|
Light Gray | Glucoses, requires full draw (may cause hemolysis if short draw) | Sodium flouride and potassium oxalate. | Antiglycolytic agent preserves glucose up to 5 days. |
Gold | Chemistries, Immunology and Serology | NONE | Serum separator tube (SST) contains a gel at the bottom to separate blood from serum on centrifugation |
Green | For lithium level, use sodium heparin for ammonia level, use sodium or lithium heparin and HPV testing. | Sodium heparin or lithium heparin | Inactivates thrombin and thromboplastin |
Light Brown | Serum lead determination | Sodium heparin | Inactivates thrombin and thromboplastin; contains virtually no lead |
Light Blue | Coagulation tests (protime and prothrombin time), full draw required | Sodium citrate | Forms calcium salts to remove calcium |
Pink | Molecular/viral load testing | Potassium EDTA | Forms calcium salts |
Red | Chemistries, Immunology and Serology, Blood Bank (Crossmatch) | NONE | Blood clots, and the serum is separated by centrifugation |
Yellow | HLA tissue typing, paternity testing, DNA studies | ACD (acid-citrate-dextrose) | Complement inactivation |
Black | Westergren Sedimentation Rate; requires full draw | Sodium citrate (buffered) | Forms calcium salts to remove calcium |
Orange | STAT serum chemistries | Thrombin | Quickly clots blood |
Dark Blue | Trace element testing (zinc, copper, lead, mercury) and toxicology | EDTA- | Tube is designed to contain no contaminating metals |
Purple | Hematology (CBC) and Blood Bank (Crossmatch); requires full draw - invert 8 times to prevent clotting and platelet clumping | EDTA | Forms calcium salts to remove calcium |
Light Green | Chemistries. | Plasma Separating Tubes(PST) with Lithium heparin. | Anticoagulates with lithium heparin; Plasma is seperated with PST gel at the bottom of the tube. |
Yellow Black | Microbiology - aerobes, anaerobes, fungi. | Broth mixture. | Preserves viability of microorgnanisms. |
