This thread is over 4 years old but I just went to that lab's website and it looks like they're still doing them. @meme how did this work out for you? Our local feed store that does clinics wanted the same per sample. I just don't have time right now to start learning to do my own. Does anyone else have a lab they use? I'm in the southwest so something a little closer would be better.
It's not looking good. I guess I'll just collect my samples and give them a try. They've been in business this long so they must be doing something right.
