Regulation
We’ve talked about the big-picture idea of Compliance, which is the “Rule book.” Now, let’s get into the specifics of how we prove we are following that rule book. This is the world of Regulation. Think of it as the scaffolding that holds up the entire structure of quality in the lab. It’s not just about having policies; it’s about the active, ongoing, and documented processes that prove those policies are alive and working every single day
These regulations can feel like a lot of paperwork and box-checking, but every single one is there for a reason, born from past errors and designed to prevent future ones. They are the mechanisms that ensure a patient’s sample is treated with the same high standard of care no matter who is working, what time of day it is, or what instrument is being used. Let’s break down the three most important pillars of regulation: Proficiency Testing, Competency Assessment, and Accreditation Standards
Proficiency Testing (PT): The Lab’s Report Card
Imagine you’re the best student in your class. You get 100% on every test the teacher gives you. That’s great, but how do you know if your teacher’s tests are too easy? How do you stack up against students in other schools? That’s what Proficiency Testing is for the laboratory. It’s our external, objective, and non-negotiable final exam
Several times a year, we enroll in a PT program (like those offered by CAP or AAB). This program sends us “blind” samples. We don’t know the expected results. We are required to treat these samples in the exact same manner as we would treat a patient specimen. We run them through our usual procedures, by the same technologists, on the same instruments. We then submit our results to the PT provider by a strict deadline
The provider then grades our performance. They compile the results from hundreds of other labs using the same method and instrument as us to determine the “target” value. Our result is then graded on how close it is to that peer-group target. A passing grade is typically required (e.g., 80% or 100% for certain analytes) for the lab to maintain its license to perform that test
Troubleshooting PT Failures
A PT failure is a five-alarm fire in the lab. It is a direct indication that something may be fundamentally wrong with our testing system. The process is immediate and serious:
- Halt Patient Testing (If Necessary) The first question is, “Could this problem be affecting our patients?” If we fail a glucose PT, we must stop and investigate our glucose testing process before reporting any more patient results
- Conduct a Root Cause Analysis This is a formal investigation. Was it a simple clerical error (e.g., a typo when submitting the result)? Was it a technical error (e.g., the instrument was out of calibration, a reagent was degrading)? Was it a methodologic issue (e.g., our specific method has an interference that others don’t)?
- Document Everything We must write up a formal Corrective Action report. This document details the failed result, the entire investigation process, the identified root cause, and the steps taken to fix the problem and prevent it from happening again. This documentation will be the first thing an inspector asks to see
Competency Assessment: The Driver’s Test
If PT is the test for the entire lab system, then Competency Assessment is the test for the individual operator. Just because a car is in perfect working order doesn’t mean the person behind the wheel knows how to drive it safely. CLIA mandates that the lab must ensure—and be able to prove—that every single person performing testing is competent to do so
This is a formal, documented process that must be completed for each employee for every test they perform. It happens upon initial hire (after training is complete), again at 6 months, and then annually thereafter. The annual competency assessment isn’t just a pop quiz; it must include, where applicable, a mix of six key elements:
- Direct Observation of the employee performing routine patient testing
- Monitoring the recording and reporting of test results (e.g., reviewing LIS entries)
- Reviewing intermediate test records, like QC, maintenance, and calibration logs
- Direct Observation of the employee performing instrument maintenance and function checks
- Assessment of Performance by testing previously analyzed (“blind”) samples or PT samples
- Assessment of Problem-Solving Skills by having the employee evaluate and troubleshoot a mock instrument flag or QC failure
Troubleshooting Competency Failures
A competency failure is not a punitive action; it’s an opportunity for improvement. It signals that there is a gap in an employee’s knowledge or skill. The response is straightforward: stop the employee from performing that specific test, provide targeted re-training, and then re-assess their competency. All of this—the failure, the re-training, and the successful re-assessment—must be documented in the employee’s file
Accreditation Standards: The Inspector’s Checklist
Accreditation is the process of having an external, independent agency (like CAP or The Joint Commission) come into your lab for an inspection to verify that you are complying with all applicable regulations. The “Accreditation Standards” are the literal checklists these inspectors use. For CAP, this is a book of thousands of detailed questions, each beginning with “Is there evidence that…?”
Think of it as the ultimate “open book test.” We have the checklist ahead of time. We know exactly what the standards are. The challenge is not knowing the rules, but being able to provide objective, documented evidence that we follow those rules every single day
Troubleshooting During an Inspection
Inspectors are not there to “get you.” They are peers and colleagues there to help you improve. When they find a potential deficiency (a failure to meet a standard), the troubleshooting process is collaborative:
- Provide Evidence: The first step is to make sure there isn’t a misunderstanding. If an inspector can’t find a temperature log, our job is to locate it for them
- Acknowledge and Explain: If a true deficiency is found (e.g., an un-dated reagent), the best approach is to acknowledge it, explain how it might have happened, and describe the system that is supposed to prevent it. This shows you understand the principles of quality
- Correct On-Site: If possible, fix the problem immediately. This demonstrates your commitment to compliance
- Formalize in a Plan of Correction: After the inspection, any identified deficiencies must be addressed in a formal Plan of Correction, as we discussed previously
Together, these three regulatory pillars—Proficiency Testing, Competency Assessment, and Accreditation Standards—form a powerful system of checks and balances that ensures the highest quality of laboratory services and, most importantly, protects the safety of every single patient we serve
Key Terms
- Regulation: The official rules and laws, such as CLIA, that govern the operation of a clinical laboratory to ensure quality and patient safety
- Proficiency Testing (PT): An external quality assessment where a laboratory analyzes blind, unknown samples from an approved provider to objectively evaluate the accuracy of its testing systems against its peers
- Competency Assessment: The required, documented process of evaluating and verifying that an individual employee has the skills and knowledge to properly perform their assigned testing duties, conducted annually
- Accreditation Standards: The detailed set of requirements, often in a checklist format, published by an accrediting body (e.g., CAP) that a laboratory must meet to become and remain accredited
- Corrective Action: The formal, documented process of investigating, resolving, and preventing the recurrence of a problem or error, such as a failed QC or PT result
- CLIA ’88 (Clinical Laboratory Improvement Amendments of 1988): The foundational U.S. federal law that establishes quality standards for all non-research laboratory testing performed on human specimens
- Standard Operating Procedure (SOP): A detailed, written document that provides step-by-step instructions on how to perform a specific task or test, serving as a primary source of evidence for consistent practice during inspections
