Rubber stoppers are commonly used in blood collection tubes to seal the tubes after blood collection. The use of rubber stoppers has been a standard practice in phlebotomy for many years. However, there is ongoing debate in the medical community about whether rubber stoppers are necessary for blood collection.
### Pros of Rubber Stoppers.
1. **Preventing Contamination**: Rubber stoppers create a tight seal on blood collection tubes, preventing contamination of the blood sample.
2. **Maintaining Vacuum**: Some blood collection tubes require a vacuum to draw blood into the tube. Rubber stoppers help maintain the vacuum in these tubes, ensuring an accurate blood sample.
3. **Sealing**: Rubber stoppers provide a secure seal, reducing the risk of leakage during transportation and storage of blood samples.
### Cons of Rubber Stoppers.
1. **Potential Risk of Chemical Contamination**: Some rubber stoppers may contain chemicals that could leach into the blood sample, affecting test results.
2. **Difficulties in Opening**: Rubber stoppers can be challenging to remove, especially for patients with arthritis or other hand mobility issues.
3. **Cost**: The use of rubber stoppers adds to the overall cost of blood collection tubes, which may not be necessary for all types of blood tests.
### Conclusion.
While rubber stoppers have been a standard component of blood collection tubes for many years, their necessity is a topic of ongoing debate in the medical community. The pros of rubber stoppers include preventing contamination, maintaining vacuum, and providing a secure seal. However, the cons such as potential chemical contamination, difficulties in opening, and added costs should also be taken into consideration. Further research and discussions are needed to determine whether rubber stoppers are necessary for all blood collection procedures.
