FDA to Regulate Clinical Lab Tests for the First Time

Lab Tests

Clinical lab tests are an integral part of medical diagnostics, playing a crucial role in informing treatment decisions. However, there has been growing concern over the accuracy and reliability of these tests. In response to these concerns, the U.S. Food and Drug Administration (FDA) recently announced its decision to regulate clinical lab tests for the first time. This move is aimed at ensuring the quality and efficacy of these vital diagnostic tools.

Previously, many Americans assumed that the FDA already had oversight of all medical tests. Surprisingly, this was not the case. However, FDA Commissioner Dr. Robert Califf believes it is high time to monitor the quality of high-tech tests used for cancer, heart disease, and other illnesses. He emphasized the increasing use of these tests in driving treatment decisions, adding that 70% of today’s medical decisions depend on laboratory test results, according to the Centers for Disease Control and Prevention.

This decision comes in light of the fact that a few corporations, such as Abbott Laboratories and Quest Diagnostics, dominate the market, developing and selling many lab tests. While some commonly used tests, like those for strep throat and COVID-19, are subject to pre-marketing FDA review, thousands of “laboratory developed tests” (LDTs) analyzed at high-tech labs evade FDA oversight. These tests are often sophisticated and used to identify cancers, sexually transmitted infections, and other conditions.

The science underlying these tests has evolved significantly since their inception decades ago. In the 1970s and 1980s, LDTs were lower risk, low volume, and used for specialized needs of local patient populations. However, changes in business practices and the ability to quickly ship patient specimens across the country have led to the wider use of LDTs. These tests now serve larger and more diverse populations, with large laboratories accepting specimens from across the country. They rely on high-tech instrumentation and software, are performed in large volumes, and have a significant impact on critical health care decisions.

Furthermore, some companies now directly market their tests to consumers, which raises concerns about the accuracy and reliability of these tests. Reports of problematic tests have increased. Inaccurate test results can have devastating consequences for patients, leading to unnecessary treatment or delayed or improper diagnosis, which can result in harm, including worsening illness or death. Instances of both over- and under-treatment for heart disease and incorrect diagnoses of conditions like autism and Alzheimer’s disease have been reported.

The FDA’s decision to regulate these tests is long overdue. The proposed changes were first introduced over a decade ago but, recently, the revelations surrounding the fraudulent blood tests made by Theranos, a Silicon Valley startup, have highlighted the urgency of this issue. Theranos founder and CEO Elizabeth Holmes was found guilty of misleading investors in the scheme.

To avoid undue disruption to the testing market, the FDA plans to phase in the new oversight gradually over the next few years. The agency believes that the net benefits of the regulations will outweigh the costs, including reducing healthcare costs associated with unsafe or ineffective tests and preventing therapeutic decisions based on false or misleading claims.

Notwithstanding the important role of LDTs in driving innovation, industry representatives have lobbied against FDA regulation, fearing that it might stifle progress in the field. To address these concerns, the FDA is welcoming comments on the proposals for the next 60 days.

In conclusion, the FDA’s decision to regulate clinical lab tests for the first time is a significant step towards ensuring the accuracy, reliability, and efficacy of these vital diagnostic tools. With the increasing use of high-tech tests in guiding treatment decisions, it is crucial to have proper oversight and regulation to safeguard public health. The FDA’s phased approach to implementation will allow for a smooth transition without disrupting the testing market. Although concerns about stifling innovation have been raised, it is essential to strike a balance between innovation and patient safety. Through this regulation, the FDA aims to enhance the quality and validity of clinical lab tests, ultimately improving patient outcomes and reducing healthcare costs associated with inaccurate or ineffective tests.
