Medical device testing is the process of demonstrating that the device is reliably and safely perform in use. In new product development, extensive design validation testing is applied. This includes performance testing, toxicity and chemical analysis, and sometimes human factors or even clinical testing. Ongoing quality assurance testing is generally more limited. This usually include dimensional checks, some functional tests, and packaging verification. Various types of medical testing services are available there in the market such as inspection services, certification services among others.
