Standardizing Clinical Data for In Vitro Diagnostics

In vitro diagnostics (IVDs) play a critical role in 66% of clinical decisions in the U.S., yet clinical data submitted for regulatory approval of IVDs often lacks consistency and structure, leading to delays in the regulatory process. The Medical Device Innovation Consortium (MDIC) has released a new resource that addresses historical challenges, the current state, and proposed approaches for definitions and adoption of data standards for clinical diagnostics.

Developed by MDIC’s Data Standardization Working Group, in collaboration with regulators and industry representatives, this paper proposes tailored data standards for IVD clinical studies, leveraging existing CDISC frameworks to reduce regulatory review times and enable faster access to innovative diagnostics.

Whether you’re a regulator, diagnostics manufacturer, data standards expert, or clinical operations leader, this resource offers actionable insights on building an industry-supported pathway toward standardized, high-quality clinical data for diagnostics.

Why Standardize IVD Clinical Study Data?

The Problem:
Currently, there is no unified standard for submitting clinical data for in vitro diagnostics (IVDs). As a result, manufacturers often rely on custom or adapted data formats, leading to inconsistencies in how clinical evidence is collected, reported, and reviewed. These inconsistencies can cause delays in regulatory review, ultimately slowing the approval of life-saving diagnostic tests—delays that become particularly critical during public health emergencies like the COVID-19 pandemic.

The Opportunity:
By aligning with existing CDISC standards—such as CDASH, SDTM, and ADaM—adapted specifically for IVDs, the industry has an opportunity to streamline the submission process. This alignment would reduce time-to-approval by creating consistent, high-quality clinical evidence that is easier to interpret and review. In turn, it would enhance data quality, improve traceability, and increase reusability throughout the diagnostic test lifecycle.
