Researched by: CompuCal Calibration Solutions
CompuCal analysed the FDA warning letters data of the last five years with the focus on calibration and maintenance issues. According to the results, 4.92% of the letters included calibration issues and 11.32% of them were related to maintenance issues.
In most of the cases, the calibration related issues could have been prevented if the companies had a compliant software solution set up.
Some important info on the research
- For this research we used data from the FDA warning letters database for the years between 2013-2017.
- In order to define which warning letters are related to calibration issues, we searched for warning letters that contained the word ‘calibration’. So, we haven’t counted any possible warning letters with calibration related issues that don’t contain the word ‘calibration’.
- Similarly, to define which warning letters include maintenance issues, we searched for warning letters that included the word ‘maintenance’. It is possible that there are more warning letters relating to maintenance that haven’t been included in the research because they don’t include the word ‘maintenance’ in their content.
3274 warning letters have been issued since 2013. In 2017, FDA issued less warning letters than in any other year between 2013-2017.
There is a decrease in warning letters that include calibration issues. In 2016 and 2017 only 3.66% and 3.51% of the warning letters included calibration issues, respectively.

• Life Sciences: pharmaceutical, medical manufacturer, dietary supplements, laboratories etc.
