Overview
Troponin I is the only troponin isotope present in the myocardium and is not expressed during any developmental stage in skeletal muscle. Troponin I is released into the bloodstream within hours of the onset of symptoms of myocardial infarction or ischemic damage. It can be detected at 3 to 6 hours following onset of chest pain, with peak concentrations at 12 to 16 hours, and remains elevated for 5 to 9 days. A troponin value above the upper reference limit (99th percentile) value is not always indicative of myocardial infarction. Other conditions resulting in myocardial cell damage can contribute to elevated cardiac troponin I levels. These conditions include, but are not limited to, myocarditis, cardiac surgery, angina, unstable angina, congestive heart failure, and noncardiac-related causes, such as, renal failure and pulmonary embolism.

What is the Cost of Troponin I
The Price of a Troponin I Test is Rs. 1100. However, cost of the Test may fluctuate depending on following factors:
-
Other tests advised along with Troponin I Test
-
Offers or discounts
-
Empanelment of the patient
What is the Purpose of the Troponin I ?
Troponin Testing is most often used to determine whether a patient's symptoms are connected to a cardiac condition. Troponin is not normally present in the blood. Appearance of even minute levels of troponin in the blood may suggest some degree of myocardial damage. Troponin testing is often used to detect acute coronary syndrome, which describes several conditions that reduce blood flow to the heart, including:
Troponin Testing is suggested for the assessment of individuals after heart-related surgery. In order to identify any damage or harm to the heart, troponin levels can be evaluated both before and after the procedure.
When is the Troponin I Recommended ?
Troponin I Test is advised if you are suffering from following symptoms:
-
Chest pain radiating to your arms, shoulders, neck, teeth, or jaw
-
Squeezing or heavy pressure on the chest
-
Sudden fatigue
-
Weakness
-
Heartburn

-
Sweating
-
Shortness of breath
-
Feeling faint
-
Lightheadedness
-
Heart palpitations
-
Irregular heartbeat
-
Anxiety
-
Feelings of impending doom
Preparation for Troponin I
-
Unless otherwise directed by your doctor, there is no need for you to make any special preparations before the Troponin I Test.
-
Other blood tests can be carried out in addition to this test. If your doctor advises you to have multiple tests at once, they may ask you to fast for a specific period of time prior to a blood test.
-
Drink adequate water before sample collection.
-
Follow the preparatory instructions as guided by your doctor.
