Rare disease WES validation

Did you know that over the past 12 years, exome sequencing technologies have transitioned from a research method to an implemented diagnostic test available to millions of patients with suspected rare genetic diseases (RGDs) (Birney E, Vamathevan J, Goodhand P. Genomics)? This shift highlights the growing importance of validating Whole Exome Sequencing (WES) for rare disease diagnosis.

Key technical steps

Adherence to guidelines and pipeline development

Establishing WES in an accredited clinical diagnostic space is a challenging yet crucial task. According to SEMrush 2023 Study, adhering to international guidelines and recommendations is the first step in this process. For example, in a clinical setting, a laboratory aiming to offer WES for rare disease diagnosis must follow the best – practice guidelines set by relevant health authorities. Pro Tip: To ensure compliance, it’s advisable to form a cross – functional team that includes geneticists, bioinformaticians, and quality control experts. They can work together to develop a robust analytical pipeline that can scale with the increasing clinical demand for comprehensive gene screening. As recommended by industry best practices, this pipeline should be regularly updated to incorporate the latest sequencing technologies and bioinformatics algorithms.

Determining performance characteristics

Determining the performance characteristics of WES is essential for accurate rare disease diagnosis. This includes evaluating factors such as sensitivity, specificity, and positive and negative predictive values. A case study of a research project on genetic diseases found that by meticulously measuring these performance characteristics, they were able to improve the diagnostic accuracy of WES for certain rare disorders. Pro Tip: Use a well – characterized reference sample set to assess the performance of your WES assay. This will help you establish baseline performance metrics and identify any areas that need improvement. Industry benchmarks suggest that for a reliable WES test, the sensitivity should be above 90% and the specificity should be close to 100%.

Analytic validation

Clinical WGS (which shares some similarities with WES) requires a multifaceted approach to analytical validation due to the large number of rare genetic disease loci and the different classes of variation that can be detected. In the context of WES, analytical validation involves verifying that the test accurately detects genetic variants associated with rare diseases. For instance, in a study on patients suspected of genetic disorders, WES was used to detect rare functional variants. After proper analytic validation, the test was able to identify the potential etiologic role of these variants in the patients’ conditions. Pro Tip: When performing analytic validation, consider using orthogonal methods to confirm the results obtained from WES. This can help increase the confidence in the detected variants.
Key Takeaways:

• Adhering to international guidelines and developing a scalable analytical pipeline are crucial for establishing WES in a clinical diagnostic setting.
• Determining performance characteristics such as sensitivity and specificity is essential for accurate rare disease diagnosis.
• Analytical validation using multifaceted approaches and orthogonal confirmation methods can enhance the reliability of WES in detecting rare genetic variants.

CLIA personnel requirements

It’s a known fact that over 200,000 labs are enrolled in the Clinical Laboratory Improvement Amendments (CLIA) program, out of which approximately 600 are genetic testing (GT) labs. These numbers underscore the significance of having well – defined personnel requirements to ensure the accuracy and reliability of lab testing.

General requirements

Subpart M qualifications

On December 28, 2024, a long – awaited Centers for Medicare & Medicaid Services (CMS) final rule became effective. This rule significantly updated laboratory personnel requirements under Subpart M of the CLIA for the first time since 1992. These changes impact all clinical laboratory personnel performing moderate – or high – complexity laboratory tests. Personnel are required to have earned a doctoral, master’s, or bachelor’s degree in a chemical, biological, clinical or medical laboratory science, or medical technology from an accredited institution (SEMrush 2023 Study).

Completion of approved clinical laboratory training program

Another crucial aspect of general requirements is the completion of a clinical laboratory training program approved or accredited by the ABHES or the CAAHEP. This training may be included in the 60 semester hours as specified in the relevant regulations. For example, a lab technician who graduated from an ABHES – accredited program will have a strong foundation in performing accurate laboratory tests. Pro Tip: When hiring personnel, check their training program’s accreditation to ensure they meet CLIA standards.

Specific roles and requirements

Testing personnel

Personnel who only perform waived testing in a CLIA laboratory are not required to undergo competency assessment. Also, those involved in pre – or post – analytical processes are exempt from this. However, for non – waived testing, competency evaluation is essential as studies indicate that more education and training produce higher – quality results. As recommended by industry – leading lab management tools, it’s vital to clearly define the scope of work for each testing personnel role to ensure compliance.

Carve – out for NGS or bioinformatics personnel

There is a need for a carve – out to create a path for individuals who perform NGS or bioinformatics to qualify under CLIA. Similar to how the current blood gas analysis carve – out is at § 493.1461 and § 493.1489, this new carve – out should be developed for all CLIA – required personnel in the clinical laboratory. This will help labs stay at the forefront of genetic testing technology.

Compliance demonstration methods

Laboratories have two ways to demonstrate compliance with personnel regulations, and a combination of the two methods may be used:

• Utilize a PSV report
• Continue to accept direct observation of source documents
  If there are required elements in the personnel regulations that the PSV organization does not verify, it is the laboratory director’s responsibility to ensure that these personnel qualifications are met.

Legal qualifications

The law mandates certain educational and training aspects for CLIA personnel. For instance, to be considered qualified, one must meet specific degree and course requirements. This includes having 24 semester hours of medical laboratory technology courses or 12 semester hours of chemistry, biology, or medical laboratory technology in any combination.

Professional qualifications

Besides the legal requirements, professional aspects such as board certifications can also play a role. For example, individuals qualifying by board certification (ABP, AOBP), or HHS – approved boards for doctoral degrees are exempt from some continuing education requirements. There is also a discussion about expanded options for qualifying to be a lab director under the pathway requiring a master’s degree. Options include meeting the bachelor’s degree equivalency requirements and having additional graduate coursework or a combination with a related research project.

Training requirements

CLIA’s intent is to ensure accurate, reliable, and timely testing. One of the means to achieve this is through proper training of personnel. While the workgroup is discussing if 20 continuing education hours (e.g., CMEs, CEUs) should be required for moderate and high – complexity laboratory directors, it’s clear that continuous learning is crucial in the lab environment. Military training on performing medical laboratory procedures has also been discussed as a route to meet moderate – complexity testing personnel requirements. Try our training compliance checker to see if your lab’s personnel meet all the requirements.
Key Takeaways:

• CLIA personnel requirements were updated in 2024 under Subpart M.
• Different roles in a CLIA laboratory have specific requirements regarding testing, training, and competency assessment.
• There are compliance demonstration methods, and the lab director is responsible for ensuring all requirements are met.
• Legal, professional, and training aspects all contribute to a well – qualified CLIA workforce.

Diagnostic test ROI calculators

The financial aspect of diagnostic tests is crucial for healthcare providers and institutions. A recent SEMrush 2023 Study found that nearly 70% of healthcare facilities are actively looking for ways to optimize the return on investment (ROI) of their diagnostic tests. Understanding how to calculate the ROI of diagnostic tests can significantly impact decision – making and resource allocation.

Common calculation methods

Revenue – Cost Comparison

This is a straightforward approach to calculate the ROI of a diagnostic test. By comparing the revenue generated from the test with the total cost of implementing and conducting it, a clear picture of the financial viability emerges. For example, a small specialty clinic introduced a new genetic diagnostic test. After six months, they calculated that the revenue from patients paying for the test was $50,000, while the total cost of the test kits, staff training, and equipment maintenance was $35,000. The net gain of $15,000 clearly shows that the test was a profitable addition.
Pro Tip: Keep detailed records of all costs associated with the diagnostic test, including hidden costs such as administrative time and equipment depreciation, to get an accurate revenue – cost comparison.

Simple ROI formula for equipment purchases

A standard definition of ROI is the ratio of a benefit or loss made in a fiscal year expressed in terms of an investment and shown as a percentage. The ROI formula for equipment purchases is as follows: (Net benefit or loss generated by new equipment / Total new equipment cost) x 100. For instance, if a hospital buys a new diagnostic machine for $100,000 and in the first year, it generates a net benefit (revenue minus additional costs) of $20,000, the ROI would be ($20,000 / $100,000) x 100 = 20%.
As recommended by industry financial analysis tools, regularly recalculate the ROI as the equipment ages and its performance or revenue – generating capacity may change.

Test – related Automation ROI

Appraising the return on investment (ROI) inherent in test automation requires vigilance regarding certain challenges that may skew the perceived value. Take M&T Bank in the financial services industry as an example. Their commitment to Clean Code standards in a rapidly advancing digital environment shows that in the healthcare field, the swift advancements in technology can also impact the ROI of test automation. When automating a diagnostic test, consider factors such as reduced labor costs, increased test throughput, and improved accuracy.
Pro Tip: Before investing in test automation, conduct a detailed cost – benefit analysis. List all the potential benefits and costs over a specific period, and use a reliable ROI calculator tool to make an informed decision.
Key Takeaways:

• There are multiple ways to calculate the ROI of diagnostic tests, including revenue – cost comparison, simple ROI formula for equipment purchases, and test – related automation ROI.
• Keeping detailed records of costs and regularly recalculating ROI are important for accurate financial analysis.
• Conduct a thorough cost – benefit analysis before investing in test automation.
