A multi-stage method for diagnosing an immunologic food sensitivity or intolerance in a companion animal. Firstly a saliva or blood spot or other non-serum bodily fluid sample is collected. The screening the saliva or blood spot or other non-serum bodily fluid sample detects the presence of at least one of IgA or IgM antibody to a particular food ingredient or composition. An immunologic food sensitivity or intolerance based on the presence of the antibody is diagnosed. Secondly a blood sample is collected and serum from the sample is screened to detect the semi-quantitative or quantitative presence of at least one of an IgA, IgM or IgG antibody or immune complex to a particular food ingredient or composition. An immunologic food sensitivity or intolerance based on the presence of the antibody or immune complex is diagnosed. Thirdly, a biologically active nutrient in relation to the animal from a molecular dietary signature is determined. The molecular dietary signature for the animal is a variation of expression of a set of genes, proteins or metabolites which may differ for the genotype of each animal.
