Heparin Blood Collection Tubes have a green top and contain spray-dried lithium,sodium or ammonium heparin on the inner walls and are used in clinical chemistry,immunology and serology.The anticoagulant heparin activates antithrombin,which blocks the clotting cascade and thus produces a whole blood/plasma sample.
Rapid Serum Tubes contain a proprietary thrombin-based medical clotting agent and a polymer gel for serum separation. They are used for serum determinations in chemistry.
They contain a special gel that separates blood cells from serum,as well as particles to cause blood to clot quickly.The blood sample can then be centrifuged,allowing the clear serum to be removed for testing.
This tube contains potassium oxalate as an anticoagulant and sodium fluoride as a preservative – used to preserve glucose in whole blood and for some special chemistry tests.
K2 K3 EDTA,used for general hematology test,not suitable for coagulation test and platelet function test.
The red cap is called ordinary serum tube, and the blood collection vessel does not contain any additives. It is used for routine serum biochemistry, blood bank and serological related tests.
Adding heparin lithium anticoagulant into the inert separation hose can achieve the purpose of rapid plasma separation. It is the best choice for electrolyte detection. It can also be used for routine plasma biochemical determination and emergency plasma biochemical detection such as ICU.
Red blood cell fragility test, blood gas analysis, hematocrit test, erythrocyte sedimentation rate and general energy biochemical determination.
The erythrocyte sedimentation tube is used for the determination of erythrocyte sedimentation rate, containing 3.2% sodium citrate solution for anticoagulation, and the ratio of anticoagulant to blood is 1:4. Slender erythrocyte sedimentation tube (glass) with erythrocyte sedimentation rack or automatic erythrocyte sedimentation instrument, 75mm plastic tube with Wilhelminian erythrocyte sedimentation tube for detection.
EDTA K2 & K3 Lavender-top Blood Collection Tube: Its additive is EDTA K2 & K3. Used for blood routine tests, stable blood collection and whole blood test.
Blood Glucose Tube
Its aditive contains EDTA-2Na or Sodium Flororide , which is used for blood glucose test
