And Design, Validate and Implement Laboratory-Developed Tests (LDT’s)
Laboratory-Developed Tests (LDTs) have garnered significant attention in recent years over questions relating to FDA oversight, clinical and analytical validity, and compliance with certain medical device regulations. Though having similar usage as an FDA-approved IVD test, an LDT is created and validated for use by a single clinical laboratory. LDTs continue to be important in the advancement of personalized medicine which has highlighted the importance of accuracy, clinical and analytical validity. To this end, regulatory authorities are increasingly requesting such studies under the more stringent CLIA regulations. At ResearchDx, we design and perform analytical and clinical validations for custom assays through our PacificDx clinical laboratory. Our CAP/CLIA certified lab, PacificDx offers state-of-the-art facilities and expertise to meet your immediate clinical and pre-clinical needs for high-quality clinical and biopharmaceutical testing services.
Fit For Purpose Development
What Level of Validation Do I require
Research Assays:
Research grade tests are usually utilized in universities or “biomarker discovery” settings. There are no specific recommendations for Research level validation. Still, at ResearchDx, all validations include an assessment of accuracy, precision, detection limits and reporatble range sufficient to demonstrate the assay is suitable for the intended use.
GLP Validation:
The objective of assay validation is to demonstrate the assay is suitable for the intended use. The regulations do not outline the requirements for validation. Still, at a minimum, a GLP validation will include documentation of accuracy, precision, and limits of detection, plus any additional studies required to demonstrate “Fit for purpose”. GLP-level assays where the data is intended for FDA submission will require additional studies.
CLIA Assay Validation:
CLIA assays are typically utilized in a routine clinical setting or for clinical studies where the testing has the potential to impact patient care. CLIA clearly defines analytical validation requirements regarding accuracy, repeatability, reproducibility, detection and quantitation limits, reportable range, and interfering substances. CLIA accrediting agencies (Including CAP and A2LA) have specific requirements that may require additional studies.
ISO-13485 Assay validation:
ISO 13485:2016 specifies the requirements for a medical device manufacturer’s quality management system (QMS). The standard outlines the QMS requirements to prove that the manufacturer can produce safe and effective medical devices that meet user needs and comply with all applicable regulations.
510(k) and PMA Validated Medical Devices:
The purpose of a 510k submission is to provide the FDA with documented evidence proving that your medical device is substantially equivalent to a predicate device, which has already been approved for marketing by the FDA. Requirements for an FDA submission include A Documented Design Controls process, including intended use, indications for use, design inputs, design verification, and anlaytical validation studies. Clinical studies may be required for some, but not all 510(k) submissions.
A PMA is more in-depth than a 510k – it proves that a new device is safe and effective for the end user. It typically requires clinical trials with human participants and analytical validation studies. The standards here are much higher than for 510k submissions, and the FDA has just 180 days to accept or reject the application.
