Color-Coded Pediatric Blood Collection Tubes in Phlebotomy: Understanding the Key Colors
Summary
- Pediatric blood collection tubes are color-coded for easy identification and to ensure proper handling of samples in phlebotomy.
- The most commonly used color-coded pediatric blood collection tubes in the United States are lavender, green, light blue, and red.
- Understanding the color codes of pediatric blood collection tubes is crucial for healthcare professionals to collect and process blood samples accurately for pediatric patients.
Introduction
In the healthcare industry, accurate and reliable Blood Testing is crucial for diagnosing and treating various medical conditions. Blood collection tubes, also known as vacuum tubes or vacutainers, are commonly used to collect blood samples for testing. These tubes are color-coded to indicate the type of additive or Anticoagulant present in the tube, which helps in ensuring the accuracy of Test Results.
When it comes to pediatric patients, special consideration must be given to their unique needs and requirements during blood collection. Pediatric blood collection tubes are specifically designed to cater to the smaller blood volume and veins of children. In this article, we will discuss the specific color-coded pediatric blood collection tubes used in phlebotomy in the United States.
Color-Coded Pediatric Blood Collection Tubes
Lavender (Purple)
The lavender or purple-topped pediatric blood collection tube is commonly used for hematological tests, such as complete blood count (CBC) and blood typing. These tubes contain ethylenediaminetetraacetic acid (EDTA) as an anticoagulant, which helps prevent blood clotting by binding to calcium ions. EDTA also preserves the cellular components of the blood, making it suitable for a wide range of hematological tests.
Green
Green-topped pediatric blood collection tubes contain Heparin as an anticoagulant. Heparin inhibits the clotting process by activating antithrombin, an enzyme that inhibits thrombin formation. These tubes are commonly used for tests that require plasma, such as electrolyte tests, arterial blood gases, and ammonia levels. It is important to note that lithium Heparin tubes are preferred for pediatric patients to minimize the risk of Heparin-induced thrombocytopenia.
Light Blue
The light blue-topped pediatric blood collection tube contains Sodium Citrate as an anticoagulant. Sodium Citrate binds calcium ions in the blood, preventing coagulation by inhibiting the clotting cascade. These tubes are primarily used for coagulation studies, such as Prothrombin Time (PT), Activated Partial Thromboplastin Time (aPTT), and D-dimer tests. It is essential to maintain the correct blood-to-Anticoagulant ratio to ensure accurate Test Results.
Red
Red-topped pediatric blood collection tubes do not contain any Anticoagulant or additive. These tubes are used for tests that require serum, such as blood chemistry tests, liver function tests, and hormone levels. After blood collection, the tube is allowed to clot, and the serum is separated from the clotted cells by centrifugation. It is crucial to allow the blood sample to clot fully before centrifugation to avoid hemolysis and ensure accurate Test Results.
Conclusion
Color-coded pediatric blood collection tubes play a crucial role in ensuring accurate and reliable Blood Testing for pediatric patients. Healthcare professionals must be familiar with the different colors of blood collection tubes and their corresponding additives to collect and process blood samples correctly. By understanding the specific color codes of pediatric blood collection tubes, Healthcare Providers can improve the quality of care provided to pediatric patients and contribute to better treatment outcomes.
