hscTnT
High-sensitivity cardiac troponin T (hs-cTnT) is a laboratory biomarker assay that measures troponin T with enhanced sensitivity and precision. The hs-cTnT test can detect very low concentrations of-troponin T in most people, enabling earlier identification of myocardial injury compared with earlier troponin assays. The 99th percentile upper reference limit commonly used for hs-cTnT is about 14 ng/L, though exact values can vary by assay lot and manufacturer.
In clinical practice, hs-cTnT is a key tool in the evaluation of patients with suspected acute coronary
Interpretation of hs-cTnT results requires clinical context. Values above the 99th percentile indicate myocardial injury but
Limitations include potential nonischemic true positives, preanalytical and analytical variability, and assay-specific characteristics.
