Capacity of a Standard Venous Blood Collection Tube: Types, Handling, and Importance
Summary
- A standard venous blood collection tube can typically hold between 2 to 10 milliliters of blood.
- There are various types of venous blood collection tubes, each designed for different tests and volumes of blood needed.
- Proper handling and labeling of blood collection tubes are crucial to ensure accurate Test Results and patient safety.
- Lavender/EDTA tubes: These tubes are used for hematology tests, such as complete blood count (CBC) and Blood Smears. They typically hold between 2 to 5 milliliters of blood.
- Red/Clot Activator tubes: These tubes are used for chemistry tests, blood bank testing, and serology. They can hold between 5 to 10 milliliters of blood.
- Green/Heparin tubes: These tubes are used for plasma determinations, such as ammonia and STAT electrolytes. They typically hold between 2 to 6 milliliters of blood.
- Gray/Glucose tubes: These tubes are used for glucose testing and other chemistry tests. They can hold between 2 to 10 milliliters of blood.
- Yellow/SPS tubes: These tubes are used for microbiology and virology testing. They typically hold between 2 to 8 milliliters of blood.
- Correctly identify the patient before collecting blood to prevent errors in labeling and sample mix-up.
- Use the appropriate type and size of blood collection tube based on the volume of blood needed for the tests ordered.
- Fill the tube to the specified level to avoid underfilling or overfilling, which can affect the accuracy of Test Results.
- Label each tube with the patient's name, date of birth, medical record number, date and time of collection, and initials of the healthcare provider.
- Handle blood collection tubes with care to prevent breakage or leakage of blood, which can pose a risk to healthcare workers and patients.
