- Control materials are used to monitor the performance of laboratory tests and to verify the accuracy of Test Results, so it is essential that phlebotomists handle them properly.
- Following the guidelines for handling and storing control materials helps to maintain the quality of laboratory testing and contributes to the overall effectiveness of patient care.
Introduction
Medical laboratory testing plays a crucial role in the diagnosis and treatment of patients. Phlebotomists are an essential part of the laboratory team, as they are responsible for collecting blood samples from patients for analysis. In order to ensure the accuracy and reliability of Test Results, phlebotomists must follow strict guidelines when handling and storing control materials in medical labs.
What are Control Materials?
Control materials are samples of known substances that are used to monitor the performance of laboratory tests and to verify the accuracy of Test Results. These materials are essential for ensuring the quality and reliability of laboratory testing. Control materials are typically made up of human blood or serum that has been spiked with specific analytes at known concentrations.
Types of Control Materials
- Positive Control: Contains the analyte at a known concentration above the reference interval.
- Negative Control: Contains no detectable amount of the analyte.
- Normal Control: Contains the analyte at a concentration within the reference interval.
Guidelines for Handling Control Materials
Phlebotomists must follow specific guidelines when handling control materials to ensure their accuracy and reliability. These guidelines help to prevent contamination and ensure that the control materials are not compromised in any way. Some common guidelines for handling control materials include:
Proper Labeling
Control materials should be properly labeled with the name of the analyte, concentration, expiration date, and any other relevant information. This helps to ensure that the control materials are used correctly and that they are not confused with other samples.
Storage Requirements
Control materials should be stored according to the manufacturer's instructions. Some control materials need to be stored at specific temperatures or protected from light to maintain their stability. It is important to follow these storage requirements to ensure the accuracy of Test Results.
Quality Control
Phlebotomists should perform regular Quality Control checks on the control materials to verify their accuracy. This may involve running control samples along with patient samples to ensure that the Test Results fall within an acceptable range. If the control results are outside of the expected range, it may indicate a problem with the testing process.
Handling and Transport
Control materials should be handled and transported with care to prevent contamination. Phlebotomists should use proper technique when pipetting control materials and ensure that they are not exposed to any potential sources of contamination. Additionally, control materials should be transported in a secure manner to prevent breakage or leakage.
Importance of Following Guidelines
Following the guidelines for handling and storing control materials is essential for maintaining the quality of laboratory testing. By following these guidelines, phlebotomists can ensure the accuracy and reliability of Test Results, which is crucial for effective patient care. Proper handling and storage of control materials also help to prevent errors and ensure that laboratory testing meets regulatory standards.
Conclusion
Phlebotomists in the United States play a critical role in the accurate and reliable performance of medical laboratory testing. By following strict guidelines for handling and storing control materials, phlebotomists can contribute to the overall quality of laboratory testing and ensure the effectiveness of patient care. It is essential that phlebotomists are aware of and adhere to these guidelines to maintain the integrity and reliability of Test Results.
