Laboratory-developed tests (LDTs) are a subset of in vitro diagnostic devices that are manufactured and used within a single laboratory. This review analyzes the current state and development prospects of LDTs based on metabolomics, comparing them with scientific metabolomics study. Legal aspects of LDT regulation in various regions are discussed, along with recommendations for further introducing metabolomic LDTs into practice.
Laboratory-developed tests (LDTs) are a subset of in vitro diagnostic devices, which the US Food and Drug Administration defines as tests that are manufactured by and used within a single laboratory. The review describes the emergence and history of LDTs. The current state and development prospects of LDTs based on metabolomics are analyzed. By comparing LDTs with the scientific metabolomics study of human bio samples, the characteristic features of metabolomic LDT are shown, revealing its essence, strengths, and limitations. The possibilities for further developments and scaling of metabolomic LDTs and their potential significance for healthcare are discussed. The legal aspects of LDT regulation in the United States, European Union, and Singapore, demonstrating different approaches to this issue, are also provided. Based on the data presented in the review, recommendations were made on the feasibility and ways of further introducing metabolomic LDTs into practice.
