Last year at Potomac someone was selling a progesterone test kit (think it was a couple thousand dollars?) and it was one you could run the numbers at home instead of running it to a lab/hospital, etc….does anyone recall the company or what it was called?
I believe it was a few thousand dollars for just the machine. They sent me some comparative info on their results vs traditional lab results, which were good. If you breed often enough using progesterone, it could easily be worth the price as long as it is accurate. They did offer to test my bitch if I sent them samples my next breeding so I could compare to lab results.
