Diagnostic Kits/USA Regulation Review
This section will detail the current state of Federal and State regulations required by government agencies for genetic tests. At present, the U.S. Food and Drug Administration ("FDA") and the Centers for Medicare & Medicaid Services ("CMS") regulate certain aspects of genetic testing. Although the vast majority of regulatory efforts are overseen by Federal Agencies, there are certain State-imposed standards for genetic tests that vary in scope by State.
Regulatory Agencies
Federal Agencies
The scope of FDA requirements, such as pre-market regulatory approvals, that apply to companies offering genetic tests depend almost entirely on the nature of the genetic test offered. In some cases, manufacturers must meet stringent requirements before marketing a genetic test, whereas in others, there are little or no substantive requirements.
CMS requires certain laboratory standards for all laboratories that conduct testing for patients in the United States. The requirements imposed by this agency are still somewhat dependent on the nature of testing conducted on the premises. For certain complex tests, including some genetic testing, laboratories must be approved by CMS and may require certain levels of supervision by highly trained individuals conducting the testing. However, for simpler tests, laboratories may perform testing without stringent oversight
State Agencies
Certain states have become increasingly involved in administering genetic testing oversight. In some cases, where states have implemented their own regulatory schemes for laboratories, laboratories located within an applicable state have become exempt from the requirements imposed by CMS. In other cases, laboratories located in a state which have state-mandated regulations that apply to laboratories must also meet CMS regulations.
New York and the state of Washington are two primary examples of where laboratories are exempt from CMS regulation. New York requires any laboratory which conducts testing to be evaluated and approved by license by the New York Department of Health before any testing can be conducted. Interestingly, these requirements also apply to laboratories that obtain specimens from patients residing within the state. Some commentators believe many laboratories avoid offering genetic testing services to New York residents.
California is an example of a state where laboratories must be both state and CMS regulations for clinical laboratory testing. Laboratories must obtain an approval license issued by the state before conducting direct-to-consumer genetic testing.
For all states that impose additional licensing or approval requirements for laboratory testing, companies manufacturing and marketing genetic tests will still be subject to any applicable FDA regulations.
Types of Genetic Tests and Testing "Services"
As previously noted, the scope of certain Federal Regulations that apply to manufacturers, marketers, and laboratories depends on the how a particular genetic test is categorized. This section will explain some of the pertinent differences of consumer genetic tests.
Most genetic tests, whether sold as a commericial testing "kit" to a laboratory or developed and an in-house "Laboratory Developed Test", utilize Analyte Specific Reagents (or "ASRs") to develop or conduct a test. ASRs are monoclonal antibodies
Genetic Testing "Kits"
Certain manufacturers of medical devices develop and sell genetic laboratory testing "kits" which include a set of test reagents and instructions for conducting a test. It's best to think of a kit as a commercial test that is manufactured and sold to several laboratories who will administer the test pursuant to the instruction within the kit.
Laboratory Developed Tests ("LDTs")
Some laboratories develop their own "in-house" genetic tests. These tests have become known as Laboratory Developed Tests (or "LDTs").
Laboratories who offer LDTs believe that LDTs are distinguishable from testing "kits" because they are not actual testing "devices", but rather testing proprietary testing "services" to be conducted only by the laboratory who developed the test. Laboratories base this distinction is based, in part, on the fact that LDTs are only used internally and are not sold to other entities. Additionally, the sale of an LDT is a sale of the necessary reagents used to develop the test. Instead, reagents are separately obtained by the laboratory from external entities.

FDA Regulations
The FDA's primary source of authority over genetic tests comes from the Food, Drug, and Cosmetic Act. This act allows[1] the FDA to regulate "medical devices" which are defined as "an instrument, apparatus, implement, machine, continuance, implant, in vitro agent, or similar or related articles, including any component, part or accessory" that is "intended for use in the diagnosis of disease or other conditions, or in the cure, mitigation, or treat or prevention of disease, in man or other animals."[2] Under this statutory authority, the FDA created and implemented a series of regulatory definitions, which further clarify what items and services are considered "medical devices," as well as a classification system which subject "medical devices" to various requirements.The FDA regulations further defined medical devices as "in vitro diagnostic products" which consistent of "those reagents, instruments, and systems, intended for use in the diagnosis of disease or other conditions."

Footnotes
- ↑ Congress approves and defines the scope of regulatory agencies by passing and enacting legislation. These laws are typically codified in the US Code. Once an agency has been created, the agency can create regulations, pursuant to its authority as defined in the U.S. Code enactment, to administer and enforce particular areas of law. Such regulations are typically codified into the Federal Registrar (sometimes referred to as the Code of Federal Regulations or "CFR"). For this reason, descriptions of regulatory provisions on this page typically include legal citations to both the CFR and US Code to describe the scope of regulatory capabilities of a particular agency, like the FDA.
