Introduction
Phlebotomy is a crucial aspect of healthcare that involves the collection of blood samples for diagnostic testing. Proper phlebotomy procedures are essential to ensure accurate Test Results and prevent complications for patients. One key aspect of phlebotomy is understanding the correct order of draw for blood collection tubes. The correct order of draw helps prevent Cross-Contamination of blood samples and ensures the integrity of the specimens. In this article, we will discuss the correct order of draw for blood collection tubes in phlebotomy procedures in the United States, highlighting the importance of following this protocol in home healthcare, clinical labs, and hospitals.
The Importance of the Correct Order of Draw
Following the correct order of draw for blood collection tubes is essential in phlebotomy procedures for several reasons:
- Prevents Cross-Contamination: Using the correct order of draw helps prevent contamination of blood samples with additives from other tubes, which can lead to inaccurate Test Results.
- Ensures accurate Test Results: Proper order of draw ensures that the blood samples are collected in tubes with the appropriate additives to preserve the integrity of the specimens for accurate Test Results.
- Promotes patient safety: Following the correct order of draw reduces the risk of complications and ensures the well-being of patients by minimizing errors in blood sample collection.
Correct Order of Draw for Blood Collection Tubes
When collecting blood samples for laboratory testing, phlebotomists must follow a specific order of draw for blood collection tubes. The correct order of draw helps maintain the quality and accuracy of the specimens. In the United States, the standard order of draw for blood collection tubes is as follows:
1. Blood Culture tubes
Blood Culture tubes are used to detect the presence of microorganisms in the bloodstream. Collecting Blood Culture tubes first helps prevent contamination of the samples with additives from other tubes.
2. Coagulation tubes (Light Blue Top)
Coagulation tubes containing Sodium Citrate are used for coagulation studies. Collecting coagulation tubes after Blood Culture tubes helps ensure accurate Test Results for coagulation studies.
3. Serum tubes without additives (Red Top)
Serum tubes without additives are used for various tests, including chemistry and serology. Collecting serum tubes without additives helps prevent interference from clot activators or anticoagulants in other tubes.
4. Serum tubes with Clot Activator (Gold Top)
Serum tubes with Clot Activator are used for chemistry tests that require serum samples. Collecting serum tubes with Clot Activator after serum tubes without additives helps ensure the proper clotting of the blood samples.
5. Heparin tubes (green top)
Heparin tubes containing lithium or sodium Heparin are used for chemistry tests that require plasma samples. Collecting Heparin tubes after serum tubes helps prevent interference with coagulation studies.
6. EDTA tubes (purple top)
EDTA tubes containing ethylenediaminetetraacetic acid are used for hematology and blood bank testing. Collecting EDTA tubes last helps prevent interference with other tests and ensures accurate results for hematology testing.
Conclusion
Understanding the correct order of draw for blood collection tubes in phlebotomy procedures is essential for maintaining the quality and accuracy of laboratory Test Results. Following the proper order of draw helps prevent Cross-Contamination of blood samples, ensures accurate Test Results, and promotes patient safety. By adhering to the standard order of draw for blood collection tubes in the United States, phlebotomists can contribute to the delivery of high-quality healthcare in home healthcare settings, clinical labs, and hospitals.
