I recently got an invitation for a medical examination. This exam is mandated by national regulations concerning office health and safety, and is for all employees who perform a certain amount of computer monitor related work. It's my first medical examination connected to a job. The invitation mentions I'll be required to give an urine sample, which I understand is normal (although I personally think it's weird because I don't see what my urine has to do with computer monitor usage).
As I mentioned, it's my first medical examination since I graduated from high school and i'm not quite sure how to prepare or what to expect. Should I be careful with what I drink or eat that day to avoid skewing the urine sample results? I'm not a smoker, I don't drink alcohol or do drugs, so I don't think that'll be an issue.
