Cardiac enzymes are proteins that are released into your bloodstream when your heart is damaged or stressed.
Therefore, they provide valuable insights into your heart health. Particularly in detecting damage to the heart muscle as well as monitoring the effectiveness of heart treatments.
Troponin is a protein found in heart muscle cells that is released during a heart injury.
Troponin is one of the most commonly tested cardiac proteins in London. It is highly specific and sensitive for diagnosing heart attacks, as elevated levels can indicate even minor cardiac damage.
At our City Walk-In Clinics, we make testing simple and stress-free. You can enjoy same-day appointments and complete price transparency with no hidden costs, designed to make your experience as smooth and convenient as possible.

A cardiac enzyme test is a standard blood test. We will collect a blood sample, typically from a vein in your arm. The process usually only takes only a few minutes. Your enzyme levels may be tested more than once over several hours. Just be prepared to return for additional tests if necessary.
You can resume normal activities immediately unless advised otherwise by your doctor. Results may take a few hours to a day. Your doctor will review the levels of cardiac enzymes and interpret their significance based on your symptoms and other tests.
