The Correct Order of Draw Steps for Phlebotomy Procedures in the United States
Summary
- The correct order of draw is essential for phlebotomy procedures.
- Following the correct order helps prevent sample contamination and ensure accurate Test Results.
- Understanding the order of draw steps is crucial for healthcare professionals in the United States.
Introduction
Phlebotomy is a crucial aspect of healthcare, especially in clinical labs and hospitals in the United States. It involves drawing blood from patients for various tests and procedures. One of the key factors in performing successful phlebotomy procedures is following the correct order of draw steps. In this blog post, we will discuss the proper order of draw for phlebotomy procedures in a medical lab in the United States.
Why is the Correct Order of Draw Important?
The correct order of draw is essential for several reasons:
- Preventing sample contamination: Following the proper order of draw helps prevent contamination of blood samples. If blood samples are drawn out of order, there is a risk of additives from one tube contaminating the sample in the next tube.
- Ensuring accurate Test Results: Drawing blood in the correct order ensures that the samples are collected in the right tubes with the appropriate additives. This helps ensure accurate Test Results and prevents misdiagnoses.
- Complying with industry standards: Following the correct order of draw is in line with industry standards and best practices in phlebotomy. It is crucial for patient safety and quality healthcare delivery.
The Correct Order of Draw Steps
There is a specific sequence that phlebotomists must follow when drawing blood from patients. The correct order of draw steps for phlebotomy procedures in a medical lab in the United States is as follows:
Step 1: Yellow (Sterile) Tube
The first tube to draw is the yellow sterile tube, used for microbiological studies.
Step 2: Light Blue Tube
The second tube should be the light blue tube, used for coagulation studies.
Step 3: Red Tube
Next, draw the red tube for various serology tests, chemistry tests, and blood bank studies.
Step 4: Tiger (Gold/Red Speckled) Tube
After the red tube, the tiger or gold/red speckled tube should be drawn for chemistry tests, including serum separator tubes (SST).
Step 5: Light Green Tube
Following the tiger tube, draw the light green tube for chemistry tests that require plasma, such as electrolytes and ammonia.
Step 6: Dark Green Tube
The dark green tube should be drawn next for STAT chemistry tests that require plasma separation, such as ammonia and lactate.
Step 7: Lavender Tube
The lavender tube comes next for Hematology tests, such as complete blood count (CBC) and Erythrocyte Sedimentation Rate (ESR).
Step 8: Gray Tube
Lastly, draw the gray tube for glucose testing, especially if the patient has fasted.
Conclusion
Understanding and following the correct order of draw in phlebotomy procedures is crucial for healthcare professionals in clinical labs and hospitals in the United States. By adhering to the proper sequence, phlebotomists can prevent sample contamination, ensure accurate Test Results, and comply with industry standards. It is essential to prioritize patient safety and quality healthcare delivery by following the prescribed order of draw steps.
