One-year in vitro stability of cardiac troponins and galectin-3 in different sample types

We assessed the long-term in vitro stability of cardiac troponins and galectin-3 under different storage conditions. We used high-sensitivity cardiac troponin I (hs-cTnI) and galectin-3 assays from Abbott and a high-sensitivity cardiac troponin T (hs-cTnT) assay from Roche. The analyte concentrations of 30 patients were measured in heparin-treated plasma, EDTA-treated plasma and serum samples after the following storage conditions: 1) samples...
