What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Order vs observation: Both
Method: High sensitivity

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

Troponin T.cardiac [Mass/volume] in Serum or Plasma by High sensitivity method

Troponin T.cardiac

The "high sensitivity" troponin assays manufactured by different vendors have different analytical characteristics, including the limit of detection and 99% upper reference limit. 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 [LOINC89577-1] and Troponin T [LOINC: 89576-3] panels. 1. The laboratory device 99th percentile upper reference limit (URL) [LOINC: 89581-3] 2. The laboratory device coefficient of variation at 99th percentile URL [LOINC: 89580-5] 3.

Interpretation for troponin T [LOINC: 89575-5] and/or troponin I [LOINC: 89578-9] [PMID: 25204966] This term is based on, but not restricted to, Roche's Troponin T high sensitivity test.
