Troponin T (high sensitivity)
A heart muscle protein; the other standard assay for heart muscle injury.
What it is
High-sensitivity troponin T serves the same purpose as troponin I on different laboratory platforms. The two are not interchangeable numerically.
Why it matters
Interpreted urgently and in context, like troponin I: unexpected elevation with symptoms is an emergency-care question.

How it affects the body
Part of heart muscle's contractile machinery, normally absent from blood in more than trace amounts.
For athletes
As with troponin I, extreme endurance work can cause small transient rises - still never a number to self-interpret.
