Key result
The Axsym and Immuno 1 cardiac troponin I assays demonstrated excellent correlation (r = 0.997) and no significant interference from hemoglobin, bilirubin, triglycerides, or rheumatoid factor.
Observational
Effect estimate: r = 0.997
Both Axsym and Immuno 1 cardiac troponin I assays demonstrate excellent correlation and analytical performance, though absolute values differ between the assays.
No takes yet. Share an insight, caveat, or question.
Supports lab flexibility with either assay; leaves open assay-specific thresholds due to differing absolute values.
Spiegeleer et al. (1999) conducted an observational in Healthy, renal failure, and muscle trauma. Axsym cardiac troponin I assay vs. Immuno 1 cardiac troponin I assay was evaluated on Correlation between the two methods (r = 0.997). The Axsym and Immuno 1 cardiac troponin I assays demonstrated excellent correlation (r = 0.997) and no significant interference from hemoglobin, bilirubin, triglycerides, or rheumatoid factor.
