GHTF-proposed general classification system
| Class | Risk level | General device examples | IVD device examples |
|---|---|---|---|
| A | Low | Surgical retractors/tongue depressors | Clinical chemistry analyser/prepared selective culture media |
| B | Low-moderate | Hypodermic needles/suction equipment | Vitamin B12, Pregnancy self-testing, Anti-Nuclear antibody, urine test strips |
| C | Moderate-high | Lung ventilator/bone fixation plate | Blood glucose self-testing HLA typing, PSA screening, Rubella |
| D | High | Heart valves/implantable defibrillator | HIV blood donor screening, HIV blood diagnostic |

| Canada | Not in operation for medical devices | |
| Japan | Good laboratory practice | |
| New Zealand | Conformity assessment | CE marked products manufactured outside the EU |
| Switzerland | Conformity assessment | |
| Turkey | Conformity assessment | |
| USA | Quality system evaluations Product evaluations Post market vigilance reports | A modular agreement with some areas excluded |
Classification of medical devices in the USA
| Classification | Risk | Device type | Regulatory requirements |
|---|---|---|---|
| Class I | Low (present minimal potential for harm to the user). | Tongue depressors, arm sling, hand held surgical instrument examination gloves. | General controls. Not exempt – 510(k). |
| Class II | Low to medium (general controls alone are insufficient to assure safety and effectiveness). | X-ray systems, gas analysers, infusion pumps, surgical needles. | General controls with special controls. Not exempt – 510(k). |
| Class III | High (insufficient information exists to assure safety and effectiveness solely through general or special controls). | Replacement heart valves, silicon gel breast implants, pacemakers. | General controls with premarket approval (PMA). |
