Improving Accuracy in Medical Laboratory Testing: Common Errors and Solutions

Summary

• Incorrect patient identification
• Inadequate specimen collection
• Improper handling and storage of specimens

Introduction

Medical laboratories play a crucial role in the healthcare system by providing accurate and timely diagnostic information to help healthcare professionals make informed decisions about patient care. Phlebotomy, the process of drawing blood for testing, is a critical step in the laboratory testing process. However, errors in the phlebotomy process or laboratory procedures can lead to tests needing to be repeated or canceled, which can delay patient care and increase Healthcare Costs. In this blog post, we will discuss some of the common errors or factors that can lead to tests being repeated or canceled in a medical laboratory setting in the United States.

Patient Identification Errors

One of the most common reasons for tests to be repeated or canceled in a medical laboratory setting is incorrect patient identification. When a specimen is collected from the wrong patient or the sample is mislabeled, there is a risk of inaccurate results being reported. This can have serious consequences for patient care, leading to incorrect diagnoses and inappropriate treatment decisions. Some factors that can contribute to patient identification errors include:

Factors Contributing to Patient Identification Errors

1. Failure to properly verify the patient's identity using two unique identifiers (e.g., name and date of birth)
2. Inadequate training of phlebotomists or other healthcare staff on proper patient identification procedures
3. High patient volumes and time pressures, leading to rushed or distracted staff

Inadequate Specimen Collection

Another common factor that can lead to tests needing to be repeated or canceled is inadequate specimen collection. If the blood sample is not drawn correctly or the specimen is contaminated during collection, the Test Results may be inaccurate. Improper technique or equipment can also lead to hemolysis (the rupture of red blood cells) or other issues that can compromise the quality of the specimen. Some possible reasons for inadequate specimen collection include:

Potential Causes of Inadequate Specimen Collection

1. Inexperienced or poorly trained phlebotomists
2. Failure to follow proper Venipuncture procedures
3. Use of expired or faulty collection tubes or equipment

Improper Handling and Storage of Specimens

After a specimen is collected, it must be handled and stored properly to ensure the integrity of the sample and the accuracy of the Test Results. Improper handling and storage of specimens can lead to sample degradation or contamination, necessitating repeat testing. Factors that can contribute to errors in specimen handling and storage include:

Potential Issues with Specimen Handling and Storage

1. Failure to label specimens correctly or incompletely
2. Exposure of specimens to extreme temperatures or light
3. Failure to transport specimens to the laboratory in a timely manner

Conclusion

Ensuring the accuracy and reliability of laboratory Test Results is essential for providing high-quality patient care. By addressing common errors in patient identification, specimen collection, and specimen handling and storage, medical laboratories can reduce the need for tests to be repeated or canceled. Proper training of healthcare staff, implementation of Quality Control measures, and adherence to standardized procedures can help prevent errors and improve the efficiency of laboratory testing processes.
