I used UBRL in January for pregnancy, CAE and Johnes tests. They were EXTREMELY helpful and I can't say enough good things about them. I was worried because I barely was able to get half a CC of blood from one of my goats and they worked with me to get the most out of the tiny sample. They told me to send in a picture of the blood tube so that I wouldn't waste money on shipping it if it was not good enough. It turned out it was OK and they were able to do all 3 tests on the lousy sample. I was so impressed with the people there and I would recommend them in a heartbeat.
