What specific type of testing does the FDA's Class 1 encompass?

The FDA’s Class 1 designation pertains to devices that are considered low-risk and are subject to the least regulatory control. These devices typically do not support or sustain human life, and the risks associated with them are minimal. Pregnancy tests fall into this category as they are designed for at-home use to provide information about a person's reproductive health without any invasive procedures or significant risk to the user.

In contrast, medical imaging devices, life-saving devices, and implantable devices are classified as Class 2 or Class 3 due to their increased complexity and higher potential risks. Class 2 devices often require special controls to ensure safety and effectiveness, while Class 3 devices necessitate the most rigorous regulatory oversight because they are meant to sustain or support life or present a potential unreasonable risk of illness or injury. Thus, pregnancy tests are appropriately classified as Class 1 devices due to their low-risk nature, straightforward functionality, and minimal regulatory requirements.
