Vacuum Blood Collection Tubes: Colors and Uses
Vacuum blood collection tubes play a crucial role in medical testing and are widely used in hospitals, blood stations, testing institutions, and disease control centers. They come in various types, differentiated by the function and color of their caps, each serving a specific purpose. Here’s a detailed breakdown of the 9 most common types:
-
Ordinary Serum Tubes (Red Cap)
These tubes are used for serum collection in routine blood tests. -
Fast Serum Tubes (Orange-Red Cap)
Designed for faster coagulation, these tubes accelerate the testing process. -
Inert Separation Gel Coagulation Tubes (Golden Yellow Cap)
These tubes contain a gel that helps separate serum from blood cells during testing. -
EDTA Anticoagulation Tubes (Purple Cap)
Commonly used in hematology tests, EDTA prevents blood clotting. -
Sodium Citrate Coagulation Test Tubes (Light Blue Cap)
These tubes are used for coagulation tests, helping monitor blood clotting disorders. -
Heparin Anticoagulation Tubes (Green Cap)
Ideal for tests that require plasma, these tubes prevent clotting with heparin. -
Plasma Separation Tubes (Light Green Cap)
Similar to the green cap, these tubes aid in plasma separation during testing. -
Potassium Oxalate/Sodium Fluoride Tubes (Gray Cap)
These tubes are typically used in glucose testing, as they inhibit glycolysis. -
Sodium Citrate Erythrocyte Sedimentation Test Tubes (Black Cap)
These are specialized tubes used for erythrocyte sedimentation rate (ESR) tests.
Each type of vacuum blood collection tube is designed for specific medical testing needs, ensuring accuracy and efficiency in blood sample handling.
