Houston Medical Testing gets three stars not because it has problems, but because it’s a place to get a drug test done… not exactly a five star experience. When you walk in, you’ll notice it’s clean and doesn’t smell… always a plus for me! There is a small window to check in. I had my drug test paperwork, they took it from me and I was told to sit down until they were ready for me. It was maybe 4 – 5 minutes later(if that) I was called and taken to a office in the back. He took my ID, I filled a little paperwork out and grabbed my cup. You are showed a small bathroom to do your business. Once done, you are good to go. The whole thing took about 8 – 10 minutes.
