All Tubes
Our standard available selection of tubes is below. Please note: we can collect into researcher provided tubes as well.
GREEN TOP (HEPARIN), 10ML
Contains 143 USP Units of Sodium Heparin. Heparin inhibits thrombin to prevent clotting.
Used for chemistry and selective hematology determinations. This anticoagulant is best for prevention of hemolysis and for osmotic fragility tests.
YELLOW TOP (ACDA-LIQUID), 8.5ML
Contains 1.50 mL of anticoagulant Acid Citrate Dextrose Solution (A). ACD-A contains nutrients to help maintain the whole blood for several weeks.
Used primarily for specific immunohematology and histocompatibility procedures requiring preservation of whole blood.
PURPLE (LAVENDER) TOP (K2 EDTA, SPRAY-COATED PLASTIC), 4ML
Contains 0.050 mL of 15% buffered solution or the calculated equivalent of 7.5 mg EDTA (K 3). EDTA or ethylenediamineteteracetic acid chelates calcium to prevent clotting.
Used primarily for hematology and specific chemistry procedures requiring plasma or whole blood. EDTA whole blood samples are superior for flow cytometry studies because the formation of artifacts is prevented, even after prolonged standing.
PURPLE (LAVENDER) TOP (K2 EDTA, SPRAY-COATED PLASTIC), 6ML
Contains 0.07 mL of 15% buffered solution or the calculated equivalent of 10.5 mg EDTA (K 3). EDTA or ethylenediamineteteracetic acid chelates calcium to prevent clotting.
Used primarily for hematology and specific chemistry procedures requiring plasma or whole blood. EDTA whole blood samples are superior for flow cytometry studies because the formation of artifacts is prevented, even after prolonged standing.
RED TOP (CLOT), 6ML
There is no additive or anticoagulant added to this tube.
Used for specific procedures requiring serum.
