Hi, I am looking to test for acetate, propionate, and butyrate. I am surprised by how hard it's been finding a lab that can test the three primary short-chain fatty acids. I would love your help in identifying a lab in the Oregon/Washington area that can handle the testing. The following labs have said they don't do that - Element, IEH, Biologic Resources, and Purity Laboratories. Eurofins in Wisconsin can do it but I would prefer a local lab if possible. Thank you!
