Preventing Inaccurate Test Results Due to Hemolysis: Immediate Action and Techniques for Phlebotomists

Summary

• Immediate action should be taken to prevent inaccurate Test Results if a blood sample is hemolyzed during the phlebotomy process.
• The phlebotomist should notify the laboratory within a timely manner to determine if the sample is still viable for testing.
• Proper training and techniques can help reduce the likelihood of hemolysis during blood collection.

Hemolysis during Phlebotomy

Hemolysis is a common occurrence during the phlebotomy process, where red blood cells break open and release their contents into the plasma or serum. This can be caused by various factors, including improper handling of the blood sample, rough handling of the vein during collection, or use of a smaller needle size than necessary. When a blood sample is hemolyzed, it can lead to inaccurate Test Results, potentially impacting patient care and treatment decisions.

Immediate Action

When a blood sample is hemolyzed during the phlebotomy process, immediate action should be taken to prevent inaccurate Test Results. Here are some steps that should be taken:

1. Stop the blood draw: If hemolysis is observed during the blood collection process, the phlebotomist should stop the draw immediately to prevent further contamination of the sample.
2. Notify the patient: Inform the patient that the sample was hemolyzed and that a new sample may need to be collected for accurate testing.
3. Label the sample: Clearly label the hemolyzed sample to alert the laboratory technicians of the potential issue.
4. Notify the laboratory: Contact the laboratory within a timely manner to inform them of the hemolyzed sample and determine if the sample is still viable for testing.

Preventing Hemolysis

While hemolysis cannot always be completely prevented, there are steps that phlebotomists can take to reduce the likelihood of hemolysis during blood collection:

1. Use the appropriate needle size: Using a needle that is too small can cause hemolysis due to increased shear stress on the red blood cells. Choose the appropriate needle size based on the size of the patient's vein.
2. Handle the blood sample gently: Avoid shaking or agitating the blood sample during collection and transport, as this can cause hemolysis. Handle the sample with care to prevent damage to the red blood cells.
3. Proper training: Ensure that phlebotomists are properly trained in blood collection techniques to minimize the risk of hemolysis. Proper technique can help reduce the likelihood of hemolysis and ensure accurate Test Results.
4. Inspect the sample: Before sending the sample to the laboratory, inspect it for signs of hemolysis, such as a pink or red color in the plasma or serum. If hemolysis is suspected, follow the steps outlined above to prevent inaccurate Test Results.

Conclusion

In conclusion, hemolysis during the phlebotomy process can lead to inaccurate Test Results and impact patient care. In the event of hemolysis, immediate action should be taken to prevent further contamination of the sample and to ensure accurate testing. Proper training and techniques can help reduce the likelihood of hemolysis during blood collection, ultimately improving the quality of patient care in medical labs across the United States.
