Plain-English summary
A study found that a new blood test for cats, called VET-SAA, is better at detecting a protein linked to inflammation and disease than an older test, LZ-SAA. This is important for diagnosing common issues like chronic kidney disease, tumors, and gingivostomatitis (inflammation of the gums and mouth). The VET-SAA test can identify low levels of this protein in both healthy and sick cats, while the LZ-SAA test only shows high levels in sick cats. Switching to the VET-SAA test could help veterinarians make more accurate diagnoses in everyday practice.

Abstract
OBJECTIVE: Comparing the utility of the anti-human serum amyloid A (SAA)-specific monoclonal and polyclonal antibodies assays (LZ-SAA) with the pure monoclonal anti-human antibody assays (VET-SAA) during clinical practice in primary care hospital populations by measuring SAA measurement in healthy and diseased domestic cats. ANIMALS: 52 healthy and 185 diseased client-owned cats. METHODS: SAA concentration was measured using different LZ-SAA and VET-SAA measurements for healthy and various diseased cats. Sensitivity, specificity, and accuracy were calculated for each disease. RESULTS: VET-SAA has higher sensitivity than LZ-SAA for the most common diseases presenting to primary care veterinary hospitals, including chronic kidney disease, tumors, and gingivostomatitis. Our results reveal the capability of detecting low SAA concentrations in healthy and diseased cats using VET-SAA in contrast to LZ-SAA, which found elevations of SAA concentrations only in diseased cats. CLINICAL RELEVANCE: Our findings indicate that switching to the new VET-SAA instead of the conventional LZ-SAA will likely enhance the diagnostic performance in primary care veterinary hospitals.
