Concentra is the Aldis of doctors offices. Only reason I ever go is if a job sends me there. I was sent there for a TB test a couple years back and was told I had TB.. I argued with the nurse and the Dr explaining that I have had a skin reaction to it before but no TB.. They continued to tell me I have it , told my job, and informed the state health center. Well I recently went to UW health and had the blood drawn test they now have and it's negative. Concentra and their fake play nurses and doctors need more training, if a patient tells you that they have some type of allergic reaction to the test before, that should be taken into consideration.
