Laboratory-Developed Tests (LDTs) offer patients the potential for preventing disease, obtaining early diagnoses, and receiving the most accurate and best course of treatment from their health care providers. Any regulatory process to oversee LDTs must appreciate the promise these tests hold without stifling innovation, while simultaneously ensuring patient safety and the accuracy, reliability, and reproducibility of LDTs. Two bills are before Congress to regulate LDTs: the VALID Act (FDA oversight) and the VITAL Act (CLIA oversight).
