what is troponin t hs test?
390254
A troponin test measures the levels of troponin T or troponin I proteins in the blood. These proteins are released when the heart muscle has been damaged, such as occurs with a heart attack. The more damage there is to the heart, the greater the amount of troponin T and I there will be in the blood.

Cardiac troponin (cTn) is the primary biomarker for the diagnosis of myocardial necrosis in an acute coronary syndrome (ACS). cTn levels can also be elevated in many other conditions, including heart failure, with significant prognostic value.

The aPTT is one of several blood coagulation tests. It measures how long it takes your blood to form a clot. Normally, when one of your blood vessels is damaged, proteins in your blood called clotting factors come together in a certain order to form blood clots and quickly stop bleeding.

A partial thromboplastin time (PTT) test is a blood test that helps doctors assess your body's ability to form blood clots. Bleeding triggers a series of reactions known as the coagulation cascade.

T4 TESTS T4 is the main form of thyroid hormone circulating in the blood. A Total T4 measures the bound and free hormone and can change when binding proteins differ (see above). A Free T4 measures what is not bound and able to enter and affect the body tissues.

A thallium stress test is a nuclear imaging test that shows how well blood flows into your heart while you're exercising or at rest. This test is also called a cardiac or nuclear stress test.

The thyroid stimulating hormone (TSH) test measures the amount of TSH in the blood. The results convey how well the thyroid is functioning. Doctors can use TSH test results to diagnose thyroid disorders, such as hypothyroidism and hyperthyroidism.

A transthoracic echocardiogram (TTE) is the most common type of echocardiogram, which is a still or moving image of the internal parts of the heart using ultrasound.

T3 has 2 forms: bound and free. Bound T3 is attached to a protein and free T3 is not attached to anything. The free T-3 test measures only the amount of free T3. The total T3 test measures both free and bound T3 in your blood.

Cardiac troponin levels are normally so low they cannot be detected with most blood tests. Having normal troponin levels 12 hours after chest pain has started means a heart attack is unlikely. A normal value range may vary slightly among different laboratories.

The Mantoux Tuberculin Skin Test (TST) is the standard method for detecting latent tuberculosis and has been provided by pharmacists since at least 2006. In the largest published study of pharmacy-based TST involving 578 patients, the most common reason for obtaining the test were employment or school requirements.

Defining hs-CRP To illustrate the difference between CRP and hs-CRP, traditional testing measures CRP within the range of 10 to 1,000 mg/L, whereas hs-CRP values range from 0.5 to 10 mg/L. In simpler terms, hs-CRP measures trace amounts of CRP in the blood.

The Mantoux tuberculin skin test (TST) or the TB blood test can be used to test for M. tuberculosis infection. Additional tests are required to confirm TB disease. The Mantoux tuberculin skin test is performed by injecting a small amount of fluid called tuberculin into the skin in the lower part of the arm.

An exercise tolerance test (ETT) records the electrical activity of your heart whilst you exercise. It is most useful in patients who experience chest pain when they exert themselves. It is also used to detect whether heart rhythm abnormalities can be brought on by exercise.

Troponin levels may remain high for 1 to 2 weeks after a heart attack. Increased troponin levels may also be due to: Abnormally fast heartbeat. High blood pressure in lung arteries (pulmonary hypertension)

The Mantoux tuberculin skin test (TST) is the standard method of determining whether a person is infected with Mycobacterium tuberculosis. Reliable administration and reading of the TST requires standardization of procedures, training, supervision, and practice.
