Term Description

The "high sensitivity" troponin assays manufactured by different vendors have different analytical characteristics, including the limit of detection and 99% upper reference limit (URL). The quantitative results from different assays should not be compared to make clinical decisions, and reporting the quantitative result in isolation is not recommended. The troponin high sensitivity quantitative results should be reported with information about the assay and/or the interpretation, depending on the specific reporting method used in a given laboratory or hospital, that are included in the High sensitivity Troponin I LOINC 89577-1 and Troponin T LOINC 89576-3 panels.
1. The laboratory device 99th percentile upper reference limit LOINC 89581-3
2. The laboratory device coefficient of variation at 99th percentile URL LOINC 89580-5
3. The laboratory device detection limit LOINC 87706-8
4. Interpretation for troponin T LOINC 89575-5 and/or troponin I LOINC 89578-9

Part Description

LP14890-5   Troponin I.cardiac
Troponin I is a part of the troponin complex. It binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place. Because of it myosin cannot bind actin in relaxed muscle. When calcium binds to the Troponin C it causes conformational changes which lead to dislocation of troponin I and finally tropomyosin leaves the binding site for myosin on actin leading to contraction of muscle. The letter I is given due to its inhibitory character. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.
