Key result
The Erenna Immunoassay System provided highly sensitive measurement of cTnI (<1 ng/L) across species, demonstrating strong correlation with the Beckman Access assay (R2=0.99).
Why the study?
Does the Erenna immunoassay system provide sensitive and precise measurement of cardiac troponin-I across multiple species?

Does the Erenna immunoassay system provide sensitive and precise measurement of cardiac troponin-I across multiple species?
Effect estimate: R2= 0.99
The Erenna immunoassay system enables ultrasensitive, cross-species measurement of cardiac troponin-I, allowing detection of small changes from normal baseline concentrations in preclinical models.
Schultze et al. (2008) conducted an observational in Cardiotoxicity biomarker measurement. Erenna Immunoassay System vs. Beckman Access cTnI was evaluated on cTnI assay sensitivity and correlation (R2= 0.99). The Erenna Immunoassay System provided highly sensitive measurement of cTnI (<1 ng/L) across species, demonstrating strong correlation with the Beckman Access assay (R2=0.99).
