- Following the correct order can help healthcare professionals provide accurate Test Results and ensure patient safety
The Importance of Proper Blood Sample Collection
When it comes to laboratory testing, the accuracy and reliability of the results depend greatly on the quality of the blood sample collected during a phlebotomy procedure. Proper blood sample collection is crucial in ensuring that healthcare professionals are able to provide accurate diagnostic information to patients and their Healthcare Providers. One of the key aspects of blood sample collection is the order in which blood samples are drawn.
Why is the Order of Drawing Blood Samples Important?
The order in which blood samples are drawn during a phlebotomy procedure is critical for several reasons:
- Preventing Cross-Contamination: Drawing blood samples in the wrong order can result in contamination of the samples and inaccurate Test Results.
- Ensuring accurate Test Results: Some test tubes contain additives or anticoagulants that may interfere with the results of other tests if drawn out of order.
- Patient safety: Drawing blood samples in the correct order can help prevent the risk of adverse events such as hematoma formation or blood clots.
Recommended Order for Drawing Blood Samples
According to the Clinical and Laboratory Standards Institute (CLSI) guidelines, the recommended order for drawing blood samples during a phlebotomy procedure in a medical lab in the United States is as follows:
1. Tubes containing additives or anticoagulants:
These tubes are typically used to collect blood samples for tests that require special additives or anticoagulants to prevent blood clotting. Examples of these tubes include:
- Light Blue Top tubes (containing Sodium Citrate for coagulation studies)
- Green top tubes (containing Heparin for plasma determinations)
- Lavender Top tubes (containing EDTA for hematology and blood bank studies)
2. Serum tubes:
After collecting tubes with additives or anticoagulants, the next step is to collect serum tubes. These tubes are used for tests that require serum samples, such as chemistry panels and hormone tests. Serum tubes typically have a red or Gold Top and do not contain any additives or anticoagulants.
3. Tubes for coagulation studies:
The final step in the recommended order for drawing blood samples is to collect tubes for coagulation studies. These tubes are used for tests that assess a patient's blood-clotting ability and typically have a Light Blue Top (containing Sodium Citrate).
Conclusion
Following the recommended order for drawing blood samples during a phlebotomy procedure is essential for maintaining accuracy, preventing contamination, and ensuring patient safety. Healthcare professionals in the United States must adhere to these guidelines to provide reliable Test Results and high-quality care to their patients. By following the proper order of drawing blood samples, Healthcare Providers can contribute to better outcomes for patients and improved overall healthcare quality.
