| abstract |
The present invention provides methods and systems to accurately detect and measure levels of endogenous antibodies, for examples endogenous IgA, to particular antigens in a biological sample from a companion animal, which is useful to diagnose inflammatory conditions, including bowel disease (IBD), in companion animals, e.g., dogs or cats. Such methods and systems identify whether a sample from the patient is associated with an inflammatory condition, by using non-invasive means, thus conveniently providing information useful for guiding treatment decisions. |
