Each individual performs only those moderate complexity tests that are authorized by the laboratory director and require a degree of skill commensurate with the individual’s education, training or experience, and technical abilities.

What are examples of moderate complexity tests?
Moderately complex tests are usually those that are available on automated clinical laboratory equipment such as electrolyte profiles, chemistry profiles, complete blood count, urinalysis, urine drug screen, and automated immunoassays.
Why do we calibrate chemistry analyzers?
Proper calibration is the first step to producing reliable results and assuring good instrument performance. For this reason laboratories should always ensure proper calibration. It establishes a reference point that helps assist instruments to produce accurate testing results.
What is calibration in biochemistry analyzer?
Calibration is the process that links the analytical signal with the concentration of analyte present in serum, urine or other body fluid. Calibration uses a series of at least five calibrators containing known concentrations of an analyte.
What is moderate complexity CLIA?
PPM procedures are certain moderate complexity microscopy tests commonly performed by health care providers during patient office visits. The PPM subcategory includes a limited set of microscopic evaluations listed in the CLIA regulations that are performed on samples such as urine, skin scrapings and excretions.
What is moderate complexity?
Moderate complexity evaluations are warranted when the patient’s condition has changing characteristics and an evolving clinical presentation. [It’s been 8 weeks since the surgery] and the fracture isn’t healing as expected (i.e. delayed healing).” This can be considered a moderate complexity evaluation.
What are the four complexity levels of CLIA?
Fundamental Aspect of CLIA Regulations The four levels of test complexity are categorized as waived, provider-performed microscopy (PPM), moderate, and high. PPM is actually a special subset of moderately complex tests.
What are the 3 categories of tests under CLIA regulations?
Current Regulation: CLIA established three categories of tests: waived tests, moderate complexity tests, and high complexity tests.
What are 3 examples of CLIA waived tests?
As defined by CLIA, waived tests are “simple laboratory examinations and procedures that have an insignificant risk of an erroneous result.” Examples of waived tests include: dipstick urinalysis, fecal occult blood, urine pregnancy tests, and blood glucose monitoring. CMS maintains a complete list of waived tests.
What is the main purpose of calibration?
The goal of calibration is to minimise any measurement uncertainty by ensuring the accuracy of test equipment. Calibration quantifies and controls errors or uncertainties within measurement processes to an acceptable level.
What is the difference between calibrator and QC?
Calibrators give a reference point for the instrument to adjust to. Controls (QC) make sure the instrument is working properly. They are basically a fake patient sample with lab values we already know. If the results match what we expect- we know the instrument is giving accurate results.
What is the basic principle of calibration?
16 December 2020 Blog. Calibration Principles: Calibration is the activity of checking, by comparison with a standard, the accuracy of a measuring instrument of any type. It may also include adjustment of the instrument to bring it into alignment with the standard.
What is difference between calibration and validation?
Calibration ensures that instrument or measuring devices producing accurate results. Validation provides documented evidence that a process, equipment, method or system produces consistent results (in other words, it ensures that uniforms batches are produced).
What is the difference between standard and calibrator?
In summary: Standards are the ideal method for evaluating assay performance but are seldom a realistic option. Calibrators are a pragmatic solution that mimic a standard and allow reference points in comparing assay results to analyte levels in patient specimens.
When should biochemistry analyzer be calibrated?
WHEN TO CALIBRATE? Calibration should be carried out when there is a possibility that the reagents’ behaviour has changed and the results are not comparable to those that were available so far.
What are considered high complexity tests?
Tests with final scores >12 are categorized as high complexity.
Who can perform moderate complexity testing in California?
A person with a baccalaureate-level license in a specialty may perform waived or moderate complexity testing in any other specialty. (BPC § 1210).
What is high complexity?
High complexity means a test system, assay, or examination that is categorized under CLIA as a high com- plexity test.
What is considered moderate MDM?
To bill for moderate MDM, your documentation must achieve at least 2 of the 3 following criteria on the coding sheet: 1) 3 problem points or higher, 2) 3 data points or higher, and 3) moderate risk in the risk table.
What is considered low complexity?
Low Complexity Medical Decision-Making requires only slightly more intellectual energy than straightforward MDM. The acuity of care remains minimal. For example, this level of MDM is required for a level 3 office visit (99213) or a level 3 office consult (99243).
What is minimal complexity?
Minimal Complexity is the product of an architectural research project initially developed at The Bartlett, UCL, which focuses on both the form-finding and the fabrication of minimal surface structures.
Is histology moderate complexity testing?
Review of the CLIA categories of tests by complexity indicates that many tasks and tests performed in the histopathology laboratory are in fact of high complexity (CFR 42 §493.5, CFR 42 §493.17).
What is the difference between CLIA and CLIA waived?
Waived tests include test systems cleared by the FDA for home use and those tests approved for waiver under the CLIA criteria. Although CLIA requires that waived tests must be simple and have a low risk for erroneous results, this does not mean that waived tests are completely error-proof.
Can phlebotomist perform moderate complexity testing?
Yes, if the phlebotomists or other non testing personnel perform bleeding times, then they will require competency assessment as a bleeding time is a moderate complexity test.
Which CLIA complexity tests can a medical assistant always perform?
Medical assistants may perform all CLIA-waived tests and some moderately complex tests, depending on the certification of the laboratory or POL in which they are employed.
