Is there an at home way to test pigs for Swine Flu?

No, as of now there are no commercial kits available to test for Swine Flu at home. The current method of identifying influenza in swine by diagnostic laboratory testing is by using PCR or ELISA, both of which require expensive equipment or expensive reagent in addition to an operator with biochemistry background and education. Pigs are most often diagnosed with influenza based on their symptomology, the same as are humans.
