**5. Discussion**

In Turkey, accreditation studies about biomedical calibration are performed in 3 different types. Calibration laboratories, testing laboratories and inspection bodies. Normally, al‐ though the scope of their applications seems like they are nested, they are separated from each other with little detail. Inspections of radiography devices and clean rooms are per‐ formed by inspection bodies. Other medical devices except for pipettes, thermometers, hu‐ midity meters that must be measured in laboratory conditions, are tested by testing laboratories and they are accredited in according to the standard of ISO IEC 17025. In cali‐ bration laboratories, it is essential to ensure appropriate environmental conditions for meas‐ urements. Because of this, measurements that require special measuring environment are performed in calibration laboratories.

If the differences and details of accreditation studies about biomedical calibration measure‐ ments are known by the health organizations, to make the right choice in the selection of calibration laboratory, testing laboratory or inspection body is inevitable.
