What is Phlebotomy Order of Draw?
Phlebotomy order of draw is the process of properly collecting and labelling blood samples from patients. It is important to follow a strict order when drawing blood to ensure the integrity and accuracy of the test results. Each type of blood draw must be collected in a specific order in order to prevent contamination. In the United States, the Clinical and Laboratory Standards Institute (CLSI) has created a universal protocol for drawing and collecting blood samples.
The order of draw is as follows: first, draw a tube containing a clot activator and gel separator (red-topped tube), then draw an EDTA tube (lavender-topped tube) followed by one or more serum tubes (gold-topped tubes). Next, draw a heparin tube (green-topped tube) followed by a tube containing a sodium citrate solution (light blue-topped tube). Finally, draw a tube containing a fluoride oxalate solution (gray-topped tube).
Why is the Order of Draw Important?
If the order of draw is not followed, the blood samples may be contaminated and the test results inaccurate. Contamination can occur when two or more different types of tubes are drawn in the wrong order. For example, if a serum tube is drawn before an EDTA tube, the EDTA anticoagulant can contaminate the serum, resulting in false test results. The order of draw also helps to prevent the cross-contamination of tubes.
What Are the Steps for a Proper Order of Draw?
It is important to follow the proper steps when collecting blood samples. Here are the steps for the order of draw:
1. Gather the necessary supplies: gloves, syringe, and tubes in the correct order.
2. Identify the patient and verify the order.
3. Prepare the patient for the blood draw.
