I had mine done at a Tufts area hospital / lab several years ago. I don't recall the exact name - I think it was around 10-15 min away from Ball Square. They had several rooms with beds - bare minimum of stuff, not all that comfortable. The lab technicians seemed competent and were friendly. The doctor at the same place that I went to see a few weeks later to discuss the results - different story. He basically told me I was wasting his time because the tests did not show anything and I didn't need them at all. (If I knew the results in advance, sure, why would I bother doing the test? Sadly for me, I didn't.)
