FDA Classification and Requirements for Approval
Under the 1976 Medical Device Amendments that established the FDA’s regulation of medical devices and tests, manufacturers are required to notify the agency of their intent to market a device. This allows the FDA to classify the device.
Class I Tests
These devices present minimal potential for harm to the user and are often simpler in design than either Class II or Class III devices.
Class II Tests
Class II devices and tests are ones for which the general controls have not been deemed sufficient to ensure safety and effectiveness; therefore, they are subject to special controls such as special labeling, mandatory performance standards, and post-market monitoring.
Class III Tests
This is the most stringent category. This class includes tests that have a new use or for which there is not enough information about their safety and effectiveness to protect the public with just general or even special controls and/or tests that are of substantial importance in preventing impairment of human health.
After FDA approval
In addition to FDA approval, all commercial tests must be evaluated by individual laboratories before they are put into use. A lab must demonstrate that it can perform the test with the same accuracy and precision as specified by the manufacturer of the test.
