Introduction
Phlebotomy is a crucial aspect of healthcare that involves drawing blood for various tests and procedures. In order to collect blood efficiently and safely, different types of tubes and needles are used in urgent care clinics. Understanding the most common types of tubes used in phlebotomy can help healthcare professionals provide high-quality care to their patients.
Evacuated tubes
Evacuated tubes are the most commonly used tubes in phlebotomy. These tubes come in various sizes and colors, each indicating a different additive inside the tube. Some of the most common colors and additives include:
- Red - Contains no additive and is used for serum chemistry tests.
- Blue - Contains Sodium Citrate and is used for coagulation studies.
- Green - Contains Heparin and is used for plasma determinations.
- Lavender - Contains EDTA and is used for whole blood hematology tests.
Syringe-based tubes
In certain situations, syringe-based tubes may be used instead of evacuated tubes. These tubes are attached to a syringe, allowing for manual control over the amount of blood collected. Syringe-based tubes are commonly used in cases where only a small amount of blood is needed, such as for pediatric patients or for specialized tests that require a specific volume of blood.
Butterfly needles
Butterfly needles, also known as winged infusion sets, are commonly used in phlebotomy for patients with Difficult Veins. These needles feature a small butterfly-shaped plastic piece that helps stabilize the needle during blood collection. Butterfly needles are ideal for patients with fragile or rolling veins, as they provide better control and reduced risk of vein collapse.
Conclusion
Understanding the different types of tubes used in phlebotomy is essential for healthcare professionals working in urgent care clinics. By knowing when and how to use evacuated tubes, syringe-based tubes, and butterfly needles, phlebotomists can ensure efficient and safe blood collection for their patients.
