Preventing Common Pre-Analytical Errors in Phlebotomy: Patient Identification, Specimen Collection, and Labeling Best Practices

Summary

• Improper patient identification
• Incorrect blood specimen collection
• Inadequate sample labeling

Introduction

Phlebotomists play a crucial role in the medical laboratory setting by collecting blood specimens for testing. However, errors can occur during the pre-analytical phase of the testing process, which can lead to inaccurate results and potential harm to patients. In this article, we will discuss some of the most common pre-analytical errors made by phlebotomists in the United States and how they can be prevented.

Improper Patient Identification

One of the most common pre-analytical errors made by phlebotomists is improper patient identification. Failing to accurately identify the patient before drawing blood can lead to serious consequences, such as misdiagnosis or incorrect treatment. Some of the common mistakes include:

1. Not asking the patient to confirm their name and date of birth
2. Not verifying the patient's identification bracelet
3. Ignoring Discrepancies in patient information

To prevent improper patient identification errors, phlebotomists should implement the following practices:

1. Always ask the patient to state their name and date of birth
2. Verify the patient's identification bracelet or other forms of identification
3. Double-check the patient's information in the electronic health record

Incorrect Blood Specimen Collection

Another common pre-analytical error made by phlebotomists is collecting blood specimens incorrectly. This can result in hemolysis, which is the breakdown of red blood cells and can lead to inaccurate Test Results. Some of the common causes of incorrect blood specimen collection include:

1. Using the wrong type of tube for the test being ordered
2. Not allowing the alcohol to dry before collecting the specimen
3. Using expired or damaged collection tubes

To prevent incorrect blood specimen collection errors, phlebotomists should adhere to the following guidelines:

1. Only use tubes that are recommended for the specific test being ordered
2. Give the alcohol enough time to dry before collecting the specimen
3. Check the expiration date and condition of collection tubes before use

Inadequate Sample Labeling

Improper sample labeling is another common pre-analytical error made by phlebotomists. Failing to label blood specimens correctly can lead to specimen mix-ups and erroneous Test Results. Some of the common mistakes include:

1. Not labeling the specimen at the bedside
2. Using the wrong label on the specimen tube
3. Illegible or incomplete labeling

To prevent inadequate sample labeling errors, phlebotomists should follow these recommendations:

1. Label the specimen at the patient's bedside immediately after collection
2. Double-check the label to ensure it matches the patient and the test being ordered
3. Use clear, legible handwriting when labeling the specimen

Conclusion

Pre-analytical errors made by phlebotomists can have serious consequences for patients and impact the quality of laboratory Test Results. By identifying the most common errors, such as improper patient identification, incorrect blood specimen collection, and inadequate sample labeling, phlebotomists can take steps to prevent these mistakes and ensure accurate Test Results. Implementing proper protocols and adhering to best practices can help to minimize pre-analytical errors and improve patient safety in the medical laboratory setting.
