- Proper procedures must be followed to ensure accurate Test Results and patient safety
Introduction
In the field of phlebotomy, proper identification and handling of blood tubes are critical components of the specimen collection process. Different colored tubes are used to collect blood samples for various laboratory tests, and it is essential for phlebotomists to understand the significance of each color tube and the procedures for handling them correctly. In this article, we will discuss the proper procedures for identifying and handling blood tubes of various colors for different laboratory tests in phlebotomy practice in the United States.
Importance of Proper Identification and Handling
Proper identification and handling of blood tubes are essential for several reasons:
- Accurate Test Results: Using the correct tube ensures that the blood sample is collected in the appropriate additive or anticoagulant, which is necessary for accurate Test Results.
- Patient safety: Mishandling blood tubes can lead to contamination of the sample or improper Test Results, putting the patient's safety at risk.
- Compliance with Regulations: Following proper procedures for identifying and handling blood tubes is a requirement to meet regulatory standards in healthcare facilities.
Common Blood Tubes and Their Colors
There are several different colored blood tubes used in phlebotomy practice, each representing a specific additive or Anticoagulant for various laboratory tests. The most common blood tubes and their colors include:
- Red: The red tube does not contain any additive or Anticoagulant and is used for collecting serum samples.
- Light Blue: The light blue tube contains Sodium Citrate and is used for coagulation tests, such as Prothrombin Time (PT) and Activated Partial Thromboplastin Time (aPTT).
- Green: The green tube contains Heparin and is used for collecting plasma samples for chemistry tests.
- Lavender: The lavender tube contains EDTA (ethylene diamine tetra-acetic acid) and is used for hematology tests, such as complete blood count (CBC).
- Gray: The gray tube contains Sodium Fluoride and Potassium Oxalate and is used for glucose testing.
Procedures for Identifying and Handling Blood Tubes
1. Verification of Patient Information
Before collecting a blood sample, it is essential to verify the patient's information, including their name, date of birth, and medical record number. This information should match the information on the blood tube label to avoid any errors in specimen identification.
2. Selecting the Correct Tube
Based on the type of test being ordered, the phlebotomist must select the appropriate colored tube for collecting the blood sample. Using the wrong tube can lead to inaccurate Test Results or Specimen Rejection.
3. Proper Order of Draw
When collecting multiple blood samples, phlebotomists must follow the proper order of draw to prevent Cross-Contamination between tubes. The recommended order of draw is as follows:
- Yellow (SPS) tube for Blood Culture
- Light Blue (Sodium Citrate) tube for coagulation tests
- Red (no additive) tube for serum tests
- Green (Heparin) tube for plasma tests
- Lavender (EDTA) tube for hematology tests
- Gray (Sodium Fluoride/Potassium Oxalate) tube for glucose testing
4. Labeling of Blood Tubes
After collecting the blood sample, the phlebotomist must label each tube with the patient's name, date of birth, and medical record number. It is crucial to label the tubes before leaving the patient's side to ensure proper identification of the specimens.
5. Handling and Transporting Blood Tubes
Once the blood tubes are labeled, they should be handled with care to prevent breakage or leakage of the specimens. The tubes should be stored in a secure container and transported to the laboratory following the facility's guidelines for specimen handling and transportation.
Conclusion
Proper identification and handling of blood tubes are essential aspects of phlebotomy practice in the United States. Understanding the significance of different colored tubes and following the proper procedures for collecting, labeling, and transporting blood samples are crucial for ensuring accurate Test Results and patient safety. By adhering to these guidelines, phlebotomists can contribute to the overall quality of patient care and the efficiency of laboratory testing processes.
