The US FDA's proposed rule on laboratory-developed tests: Impacts on clinical laboratory testing.

OBJECTIVES

To solicit quantifiable feedback from clinical laboratorians on the U.S. Food and Drug Administration (FDA) proposed rule to regulate laboratory-developed tests (LDTs) as medical devices.

DESIGN AND METHODS

A ten-item questionnaire was developed and submitted to clinical laboratory customers of ARUP Laboratories, a national nonprofit clinical laboratory of the University of Utah Department of Pathology.

RESULTS

Of 503 clinical laboratory respondents, only 41 (8 %) support the FDA's proposed rule. 67 % of respondents work in laboratories that perform LDTs and were therefore asked additional questions regarding the proposed rule. 84 % of these respondents believe that the proposed rule will negatively impact their laboratories, while only 3 % believe that they have the financial resources to pay for FDA user fees. 61 % of respondents anticipate removing tests from their laboratory menus if the proposed rule is enacted, while an additional 33 % indicated that they do not yet know. Only 11 % of respondents believe that they would pursue FDA submissions for all of their existing LDTs if the final rule is enacted. The vast majority of respondents (>80 %) were either 'extremely concerned' or 'very concerned' about the impact of the proposed rule on patient access to essential testing, financial and personnel resources to comply, innovation, the FDA's ability to implement the rule, and send-out costs and test prices.

CONCLUSIONS

The majority of clinical laboratorians surveyed do not support the FDA's proposed rule on LDTs and report having insufficient resources to comply with the rule if it is enacted.
