Laboratory Testing

Blood tests are done as part of overall medical screening to ensure your safe participation in work activities.  Common blood tests that are performed for screening include:

  • Cholesterol
  • Blood count
  • Liver function
  • Kidney function
  • Electrolytes
  • Blood sugar  

Some additional tests that are specific to your work may be requested as well:

  • Blood Lead level, if you work around metals that contain lead
  • TB, if you are exposed to people or animals potentially infected with tuberculosis
  • Cholinesterase, if you handle pesticides

For accuracy, some blood tests require fasting for 8 hours prior to having blood drawn. Drinking water prior to blood testing is permitted.

Depending on your location and employer, you may have your blood drawn during your appointment by our certified phlebotomist, or, prior to your appointment at a Quest laboratory.
