Summary
- Following the correct order of draw is crucial to ensure accurate laboratory Test Results.
- Mixing up the order of draw can lead to Cross-Contamination and inaccurate Test Results.
- Healthcare professionals must be trained to follow proper protocols for blood specimen collection.
The Importance of Following the Correct Order of Draw for Blood Specimens
When collecting blood specimens for medical laboratory testing in the United States, it is crucial for healthcare professionals to follow the correct order of draw. The order of draw refers to the sequence in which different blood collection tubes are filled during the blood collection process. This protocol is essential to ensure accurate and reliable Test Results, as mixing up the order of draw can lead to Cross-Contamination and inaccurate Test Results.
What is the Correct Order of Draw?
The standard order of draw for blood collection tubes is as follows:
- Yellow or SPS tubes (Sterile Blood Culture tubes)
- Light blue tubes (Sodium Citrate tubes for coagulation studies)
- Red tubes (No additive, or serum tubes for chemistry tests)
- Gold or tiger-top tubes (Serum separator tubes for chemistry tests)
- Light green tubes (Heparin tubes for plasma determinations)
- Dark green tubes (Heparin tubes with gel additives for chemistry tests)
- Lavender tubes (EDTA tubes for hematology tests)
- Gray tubes (Oxalate/fluoride tubes for glucose testing)
Why is it Important to Follow the Correct Order of Draw?
Following the correct order of draw is essential for several reasons:
- Prevents Cross-Contamination: Each blood collection tube is designed to contain specific additives to help preserve the integrity of the blood specimen. Mixing up the order of draw can lead to the contamination of one tube with additives from another, compromising the accuracy of Test Results.
- Ensures Accuracy of Test Results: Different blood collection tubes are used for specific laboratory tests, and following the correct order of draw ensures that each tube is filled with the appropriate amount of blood without any interference from previous tubes. This helps to avoid inaccurate Test Results that could impact patient care.
- Patient Safety: Accurate laboratory Test Results are critical for proper diagnosis and treatment of patients. By following the correct order of draw, healthcare professionals can help ensure the safety and well-being of their patients.
Training and Education for Healthcare Professionals
Healthcare professionals who are responsible for blood specimen collection must undergo proper training and education on the correct order of draw. This includes phlebotomists, nurses, and other medical staff who perform blood draws in clinical settings such as hospitals, home healthcare, and clinical labs.
It is essential for healthcare organizations to provide ongoing education and training to their staff to ensure compliance with best practices for blood collection. This includes reinforcing the importance of following the correct order of draw, proper techniques for Venipuncture, and the safe handling of blood specimens to prevent contamination.
Conclusion
Following the correct order of draw when collecting blood specimens for medical laboratory testing is a fundamental aspect of quality healthcare delivery. By adhering to the established protocols for blood collection, healthcare professionals can help ensure the accuracy and reliability of laboratory Test Results, which is essential for patient care and safety. Training and education on the correct order of draw are key components of a comprehensive quality assurance program in clinical settings across the United States.
