Procedures For Using Capillary Blood Collection Tubes.

Capillary blood collection tubes are an essential tool in the medical field, allowing healthcare professionals to safely and effectively collect blood samples from patients. Using these tubes correctly is crucial to ensure accurate test results and patient comfort. In this article, we will discuss the procedures for using capillary blood collection tubes, including preparation, collection, and storage.

Preparation

Before using capillary blood collection tubes, it is important to gather all the necessary supplies and ensure that everything is clean and sterile. Here are the steps you should follow to prepare for blood collection:

1. Gather the following supplies:
   - Capillary blood collection tubes
   - Alcohol swabs
   - Lancet device
   - Cotton balls
   - Bandages
2. Wash your hands thoroughly with soap and water.
3. Put on gloves to protect yourself and the patient from contamination.
4. Check the expiration date of the capillary blood collection tubes to ensure they are still valid for use.
5. Label the tubes with the patient's name, date of birth, and any other relevant information as required by your facility.

Collection

Once you have prepared all the necessary supplies and have properly sterilized the collection site, you can begin the blood collection process. Follow these steps to collect a capillary blood sample:

1. Select an appropriate site for blood collection. Common sites include the fingertip, earlobe, or heel of an infant.
2. Clean the collection site with an alcohol swab and allow it to air dry.
3. Use the lancet device to puncture the skin and create a small incision for blood collection.
4. Gently squeeze the area around the incision to encourage blood flow into the collection tube.
5. Fill the capillary blood collection tube to the required volume indicated on the tube.
6. Once the tube is filled, remove it from the collection site and immediately cap it to prevent contamination.
7. Apply pressure to the collection site with a cotton ball to stop any bleeding.
8. Dispose of any used supplies in a biohazard waste container.

Storage

After collecting the blood sample, it is important to properly store the capillary blood collection tube to ensure accurate test results. Follow these guidelines for storing capillary blood samples:

1. Place the capped collection tube in a biohazard bag or container for transport to the laboratory.
2. Store the tube at the appropriate temperature based on the tests being performed. Some tests may require refrigeration while others can be stored at room temperature.
3. Transport the samples to the laboratory as soon as possible to prevent degradation of the sample.
4. Ensure that the samples are properly labeled with the patient's information to prevent any errors in testing.

Conclusion

Using capillary blood collection tubes correctly is essential for obtaining accurate test results and ensuring patient comfort during the blood collection process. By following the proper procedures for preparation, collection, and storage, healthcare professionals can perform capillary blood collection with confidence and efficiency. Remember to always follow the guidelines set by your facility and consult with a supervisor if you have any questions or concerns about using capillary blood collection tubes.
