Proper Labeling and Storing of Blood Specimens in Medical Laboratories in the United States

Summary

• Proper labeling and storing of blood specimens are crucial for accurate Test Results and patient safety.
• Phlebotomists play a key role in ensuring that blood samples are labeled correctly and stored appropriately.
• Following established protocols and guidelines is essential to maintain the integrity of blood specimens in a medical laboratory setting.

Introduction

Medical laboratories play a critical role in healthcare by providing diagnostic information to help Healthcare Providers make informed decisions about patient care. One of the most common tests performed in medical laboratories is the analysis of blood specimens. It is important that these blood samples are accurately labeled and stored correctly to ensure the reliability of Test Results and the safety of patients. In this article, we will discuss the proper procedures for labeling and storing blood specimens in a medical laboratory setting in the United States.

Proper Labeling Procedures

Properly labeling blood specimens is essential to ensure that they are accurately identified throughout the testing process. Failure to label blood samples correctly can result in misdiagnosis, incorrect treatment, and potentially serious harm to patients. The following are some key guidelines for proper labeling of blood specimens:

1. Patient Identification

1. Before drawing a blood sample, phlebotomists must verify the patient's identity using at least two unique identifiers, such as the patient's full name, date of birth, or medical record number.
2. The information on the patient's wristband should be compared to the information on the test requisition form to ensure accuracy.

2. Labeling Requirements

1. Each blood specimen tube must be labeled with the patient's full name, unique patient identifier, date of birth, date and time of collection, and the initials of the phlebotomist who collected the sample.
2. The labels must be placed on the tubes immediately after collection to prevent mix-ups.

3. Chain of Custody

1. For certain tests, such as forensic or legal cases, a chain of custody form must be completed and attached to the blood specimen to document its handling and storage.
2. Phlebotomists must follow specific procedures for handling and transporting these types of specimens to maintain their integrity.

Proper Storing Procedures

Once blood specimens have been collected and labeled correctly, they must be stored properly to maintain their integrity and ensure accurate Test Results. Improper storage of blood samples can lead to sample degradation, contamination, or loss. The following are some essential guidelines for proper storing of blood specimens:

1. Temperature Control

1. Blood specimens should be stored at the appropriate temperature to prevent degradation of the sample and ensure the accuracy of Test Results.
2. Refrigerated samples should be stored at 2-8 degrees Celsius, while frozen samples should be stored at -20 degrees Celsius or lower.

2. Security and Access Control

1. Access to stored blood specimens should be restricted to authorized personnel only to prevent tampering or contamination.
2. Specimen storage areas should be secure, with limited access and appropriate monitoring to ensure the safety and confidentiality of patient samples.

3. Proper Sealing and Labeling

1. Each stored blood specimen should be properly sealed and labeled with the patient's information to prevent mix-ups and ensure traceability.
2. Specimens should be organized in a systematic manner to facilitate easy retrieval and tracking when needed.

Conclusion

Proper labeling and storing of blood specimens are critical components of the laboratory testing process. Phlebotomists play a key role in ensuring that blood samples are collected, labeled, and stored correctly to maintain the integrity of the specimens and provide reliable Test Results. By following established protocols and guidelines for labeling and storing blood specimens in a medical laboratory setting in the United States, Healthcare Providers can be confident in the accuracy and reliability of the diagnostic information they receive.
