Quality control is an essential component of any pathology laboratory. It involves the use of quality control materials to monitor the accuracy and precision of laboratory tests. Quality control materials are samples of known composition that are used to detect any errors in laboratory testing processes. Lyophilised quality controls are a type of quality control material that offers several benefits over other types of quality controls. In this article, we will explore the benefits of using lyophilised quality controls in pathology laboratories.
Stability and Longevity
Lyophilised quality controls are highly stable and have a long shelf-life. They are freeze-dried to remove moisture, which makes them resistant to degradation over time. This stability and longevity mean that lyophilised quality controls can be stored at room temperature for extended periods of time without the need for refrigeration or special storage conditions. This makes them convenient and cost-effective for use in pathology laboratories. In contrast, other types of quality control materials such as liquid-based controls require refrigeration and have a shorter shelf-life.
Consistency
Lyophilised quality controls are highly consistent from lot-to-lot. This means that the results obtained from different batches of quality controls are highly reproducible, providing assurance that the laboratory tests are consistent over time. This consistency is crucial in pathology laboratories as it ensures that the laboratory tests are accurate and precise. In contrast, other types of quality control materials may show variability between different batches, which can lead to inaccurate test results.
Accuracy and Precision
Lyophilised quality controls provide accurate and precise measurements of laboratory test performance. This is because the samples are well-characterised, and their values are known. This enables the laboratory to detect and correct any systematic errors that may be present in their testing processes. Furthermore, the stability and consistency of lyophilised quality controls ensure that the results obtained from these materials are reliable and consistent over time. This accuracy and precision are essential in pathology laboratories as they help to ensure that patients receive accurate diagnoses and treatment.
Versatility
Lyophilised quality controls are available for a wide range of laboratory tests, including hematology, chemistry, immunology, and microbiology. This versatility enables pathology laboratories to use a single supplier for all of their quality control needs. In contrast, other types of quality control materials may not be available for all laboratory tests, which can lead to the use of multiple suppliers and increased costs.
Ease of Use
Lyophilised quality controls are easy to use and require minimal preparation. The samples can be reconstituted quickly and easily with a specified amount of distilled water or buffer solution, making them ideal for high-throughput testing environments. In contrast, other types of quality control materials may require more extensive preparation or have a more complex usage procedure, which can lead to errors and reduced efficiency in the laboratory.
Conclusion
In conclusion, lyophilised quality controls offer several benefits over other types of quality controls in pathology laboratories. They provide stable, consistent, accurate, and precise measurements of laboratory test performance and are versatile and easy to use. By using lyophilised quality controls, pathology laboratories can ensure that their test results are reliable and consistent over time, improving patient care and outcomes. The benefits of lyophilised quality controls make them a crucial component of quality control in pathology laboratories.
