Why Participating in Proficiency Testing in the Laboratory is Important for Accurate Results
In the field of science and technology, it is essential to have accurate results to support research and evidence-based practice. Participating in proficiency testing, also known as PT, is one way to ensure that laboratory results are reliable and consistent. This blog article will explore the importance of participating in proficiency testing in the laboratory and how it can benefit quality assurance and patient care.
Introduction
Imagine that you need to get a lab test done to diagnose a particular health condition. You go to a laboratory, get your samples collected, and eagerly wait for the results. What if those results were inaccurate, and your diagnosis was wrong? Inaccurate results can have severe repercussions, so laboratories need to keep an eye on their quality assurance processes.
Proficiency testing checks the accuracy and precision of laboratory results, ensuring that they are reliable and trustworthy. It is a form of external quality control that measures the laboratory’s performance against other laboratories performing the same tests. Participation in PT programs is not mandatory, but it is essential for laboratories that want to demonstrate their competence and provide accurate results.

The Truth Behind Proficiency Testing
Proficiency testing is a tool used by laboratories worldwide to evaluate their performance by comparing their results with those of other laboratories. In these programs, participating laboratories receive a set of unknown samples that are analyzed alongside their regular workload, and the results are reported back to the provider of the PT program.
These programs are designed to mimic the real-world conditions of laboratories, ensuring that laboratories can produce unbiased and reliable results. Participating in PT programs identifies errors and informs the laboratory of its weaknesses, giving them the opportunity to make necessary adjustments.
Benefitting Quality Assurance and Patient Care
Proficiency testing is a robust process that has a significant impact on quality assurance, patient care, and public health. Participating in proficiency testing can improve the accuracy and reliability of laboratory results and reduce the risk of misdiagnosis or incorrect treatment.
PT programs also provide an opportunity for laboratory professionals to learn from other laboratories’ strengths and weaknesses, keeping up-to-date with new testing methods and improving methods for existing diagnostics.
Real-World Examples
The detrimental effects of inaccurate laboratory tests can have severe consequences. Suppose a medical laboratory incorrectly diagnoses diseases such as cancer, infectious diseases, or diabetes. In that case, patients can receive improper and potentially life-threatening treatments.
In 2010, the Centers for Disease Control and Prevention (CDC) found that over 80% of laboratories that tested for chlamydia in the United States participated in PT programs, with a 99.8% completion rate. However, as of 2016, only 57% of Gonorrhea testing laboratories participated in PT programs.
In the case of gonorrhea, non-participation in PT programs could lead to underdiagnosis or misdiagnosis, creating a public health concern. The latest statistics showed that gonorrhea rates in the US had reached an all-time high, highlighting the importance of accurate testing and participation in PT programs.
Conclusion
In conclusion, participating in proficiency testing in the laboratory is essential for accurate and reliable results, benefiting quality assurance and patient care. By identifying errors and informing the laboratory of its weaknesses, laboratories can improve their accuracy and precision, providing trustworthy laboratory results that support evidence-based practice. The use of PT programs is an effective way of benchmarking a lab’s performance against others worldwide, creating better quality laboratories, and ultimately improving patient outcomes.
