Abstract: A multi-stage method for diagnosing an immunologic food sensitivity or intolerance in a companion animal. Firstly a saliva or other non-serum bodily fluid sample is collected. The screening the saliva 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 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.

Abstract: Improved methods for the separation, isolation, enrichment, or detection of target molecules, such as nucleic acids and proteins, within dilute or heterogeneous samples, such as bodily fluids, excreta or tissue samples, are disclosed. The methods include repetitively and rapidly passing a sample across at least one region of a conduit in which at least one region includes a binding partner specific for the target molecule. In certain methods, at least one other region includes binding partners specific for non-target molecules. The sample may be passed over the binding partner in the same direction if the conduit is a loop or in an antiparallel direction (i.e., back and forth over the binding partner). In an embodiment, the sample is electrophoresed through or over an electrophoretic medium, in which at least one region includes a binding partner for the target molecule. The invention also provides apparatus and sample preparation systems adapted for use in the methods.

The MSP may be dispersed in a sample containing a target ligand such that the target ligand binds thereto. A driver is also provided to emit a varying magnetic field such that the MSP produces a resonance response detectable by a measurement device configured to receive and detect changes in the resonance response that are due to alterations of the binding element. The MLSD and assays find use in identifying and quantitating ligands as well as chemicals and environmental conditions in a sample or patient.
