Horse SAA

Jacobsen S, et al. Validation of an equine serum amyloid A assay with an unusually broad working range. BMC Vet Res 15, 462 (2019).   PubMed >

“The assay was unique in its ability to measure SAA concentrations with acceptable reliability over an extreme concentration range. This is relevant in the equine species, where SAA concentrations may reach very high concentrations” (Jacobsen et al. 2019)



Waugh EM, et al. Validation of an automated immunoturbidimetric assay for feline serum amyloid A. BMC Vet Res. 2022;18(1):359.   PubMed >

“The automated VET-SAA assay is a robust, precise, and accurate method for measurement of feline SAA which can clearly identify patients with inflammatory disease. It should be a valuable biomarker for use in feline medicine.” (Waugh et al. 2019)



Behling-Kelly E, et al. Acute phase protein response and changes in lipoprotein particle size in dogs with systemic inflammatory response syndrome. J Vet Intern Med. 2022;36(3):993-1004.    PubMed >

"The SAA assay met desired performance characteristics and was deemed reliable for clinical use in dogs. [...] The wider range of the new SAA assay as compared to its predecessors, higher concentrations of SAA found in dogs with sepsis" (Behling-Kelly et al. 2022)


Rabbit SAA

Lennox A, et al. Preliminary evaluation of an immunoturbidimetric assay and lateral flow device for the measurement of serum amyloid A in rabbits. Journal of Exotic Pet Medicine. 33 (2020) 54-56.  Science Direct >

“Reference laboratory testing for APPs allows for accurate measurement of SAA and CRP [...] Additional studies may show that APPs can have value in the diagnosis and prognosis of diseases in rabbits.” (Lennox et al. 2020)



Otsuka M, et al. Diagnostic utility of measuring serum amyloid A with a latex agglutination turbidimetric immunoassay in bovine mastitis: comparison with haptoglobin and alpha 1 acid glycoprotein. J Vet Med Sci. 83(2): 329–332, 2021.   J-Stage >

"Only the plasma SAA concentration in cows with clinical mastitis (44.90 mg/l; n=15) was significantly higher than that in those with subclinical mastitis (10.70 mg/l; n=16), enabling their diagnosis in contrast to other APPs. Thus, the SAA assay using a LATIA reagent is useful in assessing mastitis severity due to its higher sensitivity and specificity than other APP assays." (Otsuka et al. 2020)
