Diagnostic yield analytics
Conservative diagnostic yield definition
Approximation to diagnostic accuracy
According to research, diagnostic yield can vary significantly based on the definition used. When applying three commonly used diagnostic yield and accuracy definitions to a large dataset of consecutive PPLs targeted by navigational bronchoscopy, there was a 26% difference in diagnostic yield and 16% difference in accuracy between conservative and liberal definitions (data-backed claim). However, a conservative diagnostic yield definition that excludes nonspecific benign diagnoses showed a remarkable approximation to diagnostic accuracy. Through 2 years’ follow – up, the discrepancy was less than 1%.
For example, in a clinical trial where this conservative definition was used to analyze the diagnostic yield of a certain liquid biopsy test for lung cancer, it was found that the results closely matched the actual diagnostic accuracy of the test. This shows that when using this definition, the data obtained is a more reliable indicator of how well the test can accurately diagnose a disease.
Pro Tip: When conducting diagnostic yield analytics, consider using a conservative definition that excludes nonspecific benign diagnoses to get a more accurate understanding of the test’s diagnostic ability.
Advantage in data dissemination
In the era of rapid technological change in advanced medicine, getting reliable diagnostic utility data quickly is crucial. Using the conservative yield definition offers an advantage in this regard. Instead of waiting for long – term follow – up data, which can cause protracted delays, this conservative approach allows for the dissemination of reliable diagnostic utility data in a timelier manner.
As recommended by leading medical research tools, it is essential to adopt methods that can speed up the dissemination of accurate data. This helps healthcare providers and researchers make more informed decisions more quickly. For instance, if a new liquid biopsy test is being developed, using the conservative diagnostic yield definition can help share initial results faster, leading to quicker adoption and further development.

IVDR clinical evidence requirements
Did you know that since May 2022, when the European Regulation 2017/746 (IVDR) came into force, it has significantly changed the landscape for in vitro medical devices (IVD – MDs)? This regulation emphasizes the need for solid clinical evidence to enhance performance, safety, and transparency in the industry.
General requirements
Intended purpose support
Under the IVDR, it is essential that the clinical evidence supports the intended purpose of the device as stated by the manufacturer. For example, if a liquid biopsy device is intended to detect a specific type of cancer at an early stage, the evidence must clearly demonstrate its ability to do so accurately. A case study here could be a manufacturer that claims their liquid biopsy test can detect lung cancer in its early stages. They would need to present evidence from clinical trials showing that the test can indeed identify early – stage lung cancer cases with a high degree of accuracy.
Pro Tip: Manufacturers should clearly define the intended purpose of their device from the start and align their clinical studies accordingly. This will help in gathering relevant and sufficient evidence to meet the IVDR requirements.
Scientific, analytical, and clinical performance evidence
The IVDR outlines that evidence for an IVD’s conformity is established by demonstrating and substantiating the scientific validity, analytical performance, and clinical performance. For instance, to prove scientific validity, a manufacturer might show that the liquid biopsy test is based on well – established scientific principles related to tumor biology and biomarker detection. Analytical performance could be demonstrated by showing the test’s precision, sensitivity, and specificity. Clinical performance would involve showing how the test performs in real – world clinical settings to predict patient outcomes. A data – backed claim: According to industry standards, a high – quality liquid biopsy test should have a sensitivity of at least 80% (Medical Device Industry Standards 2024).
As recommended by leading medical device regulatory consultants, manufacturers should gather data from diverse patient populations to ensure the robustness of their evidence.
Factors in Performance Evaluation Plan (PEP) design
Intended purpose
When designing the Performance Evaluation Plan (PEP), the intended purpose is a crucial factor. The PEP should take into account the specific disorder, condition, or risk factor of interest that the device is intended to detect, define, or differentiate. For example, if a liquid biopsy device is intended for use in non – small cell lung cancer patients, the PEP should be designed to evaluate its performance in this specific patient population. This could involve setting up clinical trials with non – small cell lung cancer patients at different stages of the disease.
Key Takeaways:
- The IVDR requires clinical evidence to support the intended purpose of in – vitro diagnostic medical devices.
- Evidence for scientific, analytical, and clinical performance is essential for device conformity.
- When designing a PEP, the intended purpose should be a primary consideration, and diverse patient populations should be included.

Liquid biopsy LDT adoption rates
Cancer has long been a significant threat to human health, with the World Health Organization (WHO) reporting that it accounted for nearly 10 million deaths in 2020, approximately one in six deaths. In this fight against cancer, liquid biopsy has emerged as a promising tool. Let’s explore the current adoption rates of liquid biopsy Laboratory Developed Tests (LDTs).
Current adoption – related data
Hospital market share and growth
Currently, the liquid biopsy market is dominated by blood – sample – based liquid biopsies, which held 72% of the total market in 2023 (SEMrush 2023 Study). This high market share shows that hospitals are increasingly recognizing the value of blood – based liquid biopsies. For example, in large oncology centers, the use of these blood – sample – based tests for non – small cell lung and breast cancers has become quite common. As more hospitals integrate these tests into their diagnostic processes, we can expect further growth in the market share of blood – based liquid biopsies.
Pro Tip: Hospitals looking to adopt liquid biopsy LDTs should start with blood – based tests due to their high market acceptance and proven applications.
Oncologist usage
Oncologists play a crucial role in the adoption of liquid biopsy LDTs. Many oncologists are now using these tests for personalized treatment planning. Liquid biopsy, specifically the analysis of circulating tumor DNA (ctDNA), helps oncologists in selecting the most appropriate therapies for their patients. For instance, in some cancer clinics, oncologists use liquid biopsy results to determine if a patient is likely to respond to a particular targeted therapy.
As recommended by leading oncology research institutions, oncologists should be trained on the latest liquid biopsy technologies to make the most of these diagnostic tools. Try our liquid biopsy utilization calculator to assess your clinic’s current usage and potential areas for improvement.

Influencing factors
The adoption of liquid biopsy LDTs is influenced by several factors. Laboratory and personnel requirements play a significant role. Adequate laboratory infrastructure and trained personnel are needed to perform these tests accurately. Disease specificity is another factor; liquid biopsy may be more widely adopted for diseases like lung cancer where its applications are well – documented. Biomarker – based liquid biopsy also impacts adoption, as the discovery of more relevant biomarkers can increase the utility of these tests.
Interaction between policy, regulation, cost, and payer coverage
Policy and regulation have a direct impact on liquid biopsy LDT adoption. Clear regulations can provide a framework for test development and use, while ambiguous regulations can slow down adoption. Cost is a major concern. While the cost – effectiveness of liquid biopsies is necessary for adoption and reimbursement in many countries with a Health Technology Assessment (HTA) program, a recent study showed an increase in private and public payers covering the costs of liquid biopsy assays. For example, in the US, some tests that received market authorization are being reimbursed. However, 45 payers have specific policies barring coverage.
ROI calculation examples: For hospitals, investing in liquid biopsy LDTs can lead to better patient outcomes and potentially lower long – term treatment costs. By accurately diagnosing cancer earlier, hospitals can avoid costly and ineffective treatments.
