We have used Lab Corp before with satisfactory results but today was a bummer. I expect the technicians to be proficent in what they do because they do it all day. However, the technician started with my left arm and made a very painful stab and after awhile pulled out the needle and but on the cotton etc. Then she started swabbing my arm again and I asked if she needed two specimens and she said the first was unsuccessful. I ask her to loosen the tape on the first try because it was hurting. She took it off. I gave her my other arm and I guess she was successful but it hurts,too. I expect them to be better than that. read more
