“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).

“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)

“Hepatic SAA2 and SAA4 mRNA abundance significantly increased from 4 hr after administration, and remained significantly higher than those pre-values up to 12 and 24 hr, respectively. [...] The major isotype was SAA2 in liver tissue, and it is indicating systemic inflammation in cattle.” (Otsuka et al. 2020)

"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)
