Blood Collection Tube

Cat NO.: AN-0075

Product Name: Blood Collection Tube

Certification: FDA

This product is used to safely and efficiently collect blood samples for medical testing and analysis.

Product Features

• Safe Collection: Provides a sterile environment to ensure that blood samples are not contaminated during collection, preventing cross-contamination.
• Stable Storage: Effectively stores blood samples, ensuring their stability during transport and storage, and preventing sample degradation.
• Prevention of Coagulation: Some blood collection containers contain anticoagulants to prevent blood from coagulating, ensuring the sample is suitable for blood analysis and testing.

Product Types

Red-Top Blood Collection Tube

Main Components

• Tube Material: PP, PET.
• Coagulant: The red-top tube generally does not contain any anticoagulant, hence it is also referred to as a "non-anticoagulant tube." It is used for blood samples that need to coagulate naturally.

Main Functions

• Blood Coagulation: Blood coagulates naturally in the red-top tube, separating into a clot and serum.
• Serum Testing: The serum is used for biochemical tests after coagulation.
• Serum Sample Tests: Commonly used for tests requiring serum, like liver and kidney function tests.

Purple-Top Blood Collection Tube (EDTA)

Main Components

• Tube Material: PP, PET.
• EDTA: A strong anticoagulant that prevents blood from clotting by binding calcium ions, which are essential for blood coagulation.

Main Functions

• Prevents Blood Coagulation: EDTA in the tube prevents blood from clotting, ensuring the preservation of blood cells for analysis.
• Used for Hematological Tests: Commonly used in complete blood count (CBC) tests, blood smears, and other tests requiring whole blood or plasma.
• Preserves Cell Morphology: EDTA helps preserve the shape and structure of blood cells for accurate analysis under a microscope.

 Gray-Top Blood Collection Tube (Sodium Fluoride)

Main Components

• Tube Material: PP, PET.
• Sodium Fluoride and Potassium Oxalate: Sodium fluoride acts as a glycolysis inhibitor to preserve glucose levels, while potassium oxalate serves as an anticoagulant.

Main Functions

• Prevents Glycolysis: Sodium fluoride inhibits glycolysis, preserving glucose in the blood sample.
• Prevents Coagulation: Potassium oxalate prevents blood clotting.
• Used for Glucose Testing: Commonly used for blood glucose testing, including fasting blood sugar (FBS) and glucose tolerance tests.

Yellow-Top Blood Collection Tube (Clot Activator/Serum Separator Gel)

Main Components

• Tube Material: PP, PET.
• Clot Activator: Typically includes silica gel or other chemical agents to promote rapid blood clotting.
• Serum Separator Gel: A gel that forms a barrier after coagulation, separating the serum from the blood clot.

Main Functions

• Promotes Blood Coagulation: The clot activator accelerates the coagulation process, allowing serum and blood clot separation.
• Serum Separation: After coagulation, the gel forms a layer that separates the serum from the clot for easy collection.
• Used for Serum Testing: Commonly used for tests requiring serum, such as hormone monitoring, drug testing, and immunological assays.

Blue-Top Blood Collection Tube (Sodium Citrate)

Main Components

• Tube Material: PP, PET.
• Sodium Citrate: An anticoagulant that prevents blood clotting by binding calcium ions, which are essential for the coagulation process.

Main Functions

• Prevents Blood Coagulation: Sodium citrate inhibits coagulation by binding calcium ions, maintaining the liquid state of the blood sample.
• Used for Coagulation Testing: The blue-top tube is commonly used for tests such as International Normalized Ratio (INR), Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and other clotting tests.
• For Monitoring Anticoagulation Therapy: It is also used for monitoring anticoagulation therapy or coagulation functions in patients undergoing treatments like dialysis.

Green-Top Blood Collection Tube (Heparin)

Main Components

• Tube Material: PP, PET.
• Heparin: An anticoagulant that prevents blood clotting by inhibiting thrombin and other clotting factors.

Main Functions

• Prevents Blood Coagulation: Heparin prevents blood clotting, making it suitable for tests that require an anticoagulated blood sample.
• Used for Blood Gas and Chemical Testing: The green-top tube is commonly used for blood gas analysis, electrolyte testing, enzyme assays, and drug monitoring.
• For Tests Requiring Whole Blood or Plasma: It is used when whole blood or plasma is needed for the analysis.
