A troponin test looks for a protein that’s unique to heart muscle. Damage to those cells, such as from a heart attack, is the sole cause of troponin in your blood.

Apr 17, 2025 · Troponin refers to three different proteins that help regulate the contractions of the heart and skeletal muscles. Normal troponin levels range from 0 to 0.04 nanograms per milliliter (ng/ml).

Nov 23, 2025 · High troponin levels in your blood can be a sign of heart damage and can help your provider identify cardiac issues such as heart attack. This marker helps diagnose heart health …

Troponin, or the troponin complex, is a complex of three regulatory proteins (troponin C, troponin I, and troponin T) that are integral to muscle contraction [2] in skeletal muscle and cardiac muscle, but not …

Sep 29, 2025 · Troponin is a protein that appears in the blood only when the heart muscle is damaged, as in a heart attack. There are other causes of elevated troponin, but a heart attack is the most …

Troponin is a protein that's found in the cells of your heart muscle. Normally, troponin levels in blood are so low that only the most sensitive types of tests can measure them. But if your heart muscle is …

Troponin is a protein found within the muscle cells of the heart. It is a complex of three subunits: troponin C, troponin I, and troponin T, all of which play a role in muscle contraction and relaxation.

Aug 15, 2025 · Cardiac troponin I and T are specific and sensitive biomarkers of myocardial injury. They are the preferred serologic tests for the evaluation of patients with suspected acute myocardial …

Inside each of these cells, you'll find a special protein called troponin. Its main job is to help your heart muscle contract and relax with every single beat, a tiny, critical switch for a life sustaining function.

Jul 15, 2025 · Troponin is a protein in heart muscle. A troponin test measures troponin in blood. High levels may indicate heart damage. Learn about uses, testing and results.
