Unraveling the Mystery Behind Why Is It Called a Red Top Tube
Have you ever had a blood test and seen the technician reach for a tube with a red cap? If so, you may have wondered why it is called a "Red Top Tube." In this article, we will explore the origins and significance of this common medical device.
What is a Red Top Tube?
A Red Top Tube is a type of blood collection tube used in medical settings to obtain blood samples for laboratory analysis. It is characterized by its red-colored cap, which helps to distinguish it from other types of tubes used for blood collection.
Origins of the Red Top Tube
The use of color-coded tubes for blood collection dates back to the mid-20th century when the Vacutainer system was introduced by the Becton Dickinson company. This system revolutionized blood collection by allowing for the collection of multiple samples in a single tube, reducing the need for multiple venipunctures.
Why is it Called "Red Top"?
The reason why the Red Top Tube is called as such is due to the color of its cap. The red color serves as an important indicator for both Healthcare Providers and laboratory technicians, signaling that the tube contains a specific type of additive that is necessary for certain types of laboratory tests.
Uses of Red Top Tube
The Red Top Tube is commonly used for the collection of serum samples, which are obtained by allowing blood to clot before centrifugation. Serum is the liquid portion of blood that remains after the clotting factors have been removed, making it ideal for a variety of laboratory tests.
Types of Tests Using Red Top Tube
- Basic metabolic panel
- Complete blood count
- Lipid panel
- Liver function tests
- Thyroid function tests
Importance of Proper Handling
It is important for Healthcare Providers to follow proper procedures when collecting blood samples in Red Top Tubes to ensure accurate and reliable Test Results. This includes proper labeling of tubes, correct order of draw, and appropriate handling and storage of samples.
Order of Draw
The order of draw refers to the sequence in which blood samples are collected when using multiple tubes for testing. This is important to prevent Cross-Contamination between different additives and ensure accurate Test Results.
- Yellow (SPS) Tube
- Light Blue (Citrate) Tube
- Red (No Additive) Tube
- Gold (SST) Tube
- Green (Heparin) Tube
- Lavender (EDTA) Tube
Proper Labeling
Each Red Top Tube should be properly labeled with the patient's name, date of birth, and medical record number to ensure traceability and prevent errors in sample identification. Additionally, the tube should be labeled with the date and time of collection.
Handling and Storage
After collection, Red Top Tubes should be gently inverted several times to ensure thorough mixing of the blood and the Clot Activator. The tubes should then be allowed to clot at room temperature for 30 minutes before centrifugation. After centrifugation, the serum should be separated from the clot and transferred to a separate tube for testing.
Conclusion
In conclusion, the Red Top Tube plays a crucial role in the collection and analysis of blood samples in medical settings. Its distinct red cap serves as a visual cue for Healthcare Providers and laboratory technicians, indicating the presence of a specific additive for laboratory testing. By following proper procedures for collection, handling, and storage of blood samples in Red Top Tubes, Healthcare Providers can ensure accurate and reliable Test Results for patient care.
