For parasites, we were doing everything manually, everything with the same methods, everything done by British Naval doctors in the 1800s. To think that we hadn't come very far in 200 years and as a community bemoaning how insensitive microscopy is, and all the flaws with it, and all the challenges. It just didn't make sense that we wouldn't try molecular. At ARUP, we embrace new technologies and try to modernize our tests and make them better. Once ordering physicians have used molecular for parasite screening, they become users. They are not going to go back to O&P. Unless it's a scenario where they think the patient has Schistosoma or hookworm, or something that isn't targeted, then they would supplement with O&P.
