76399-5Troponin I.cardiac [Presence] in Serum, Plasma or Blood by Rapid immunoassayActive

Term Description

This term was created for, but not limited in use to, the LifeSign MI Troponin I test kit, employing solid-phase chromatographic immunoassay technology that produces results in a little over 15 minutes. The qualitative nature of this assay does not provide information about change, either the rise or fall, in the concentration of cTnI with a single testing.

Part Descriptions

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.

LP14890-5   Troponin I.cardiac
The troponin test is used to help diagnose a heart attack, to detect and evaluate mild to severe heart injury, and to distinguish chest pain that may be due to other causes. Troponin values can remain high for 1–2 weeks after a heart attack. The test is not affected by damage to other muscles, so injections, accidents, and drugs that can damage muscle do not affect troponin levels. Troponin may rise following strenuous exercise, although in the absence of signs and symptoms of heart disease, it is usually of no medical significance.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
Order vs. Observation
Both
