Determination of the 99th Percentile Upper Reference Limits (URLs) for the SpinChip High Sensitivity Cardiac Troponin I (SpinChip Hs-cTnI) Test
During a heart attack, the protein troponin I is released from the heart muscle into the bloodstream. Measurements of cardiac troponin in blood are used as an aid in the diagnosis of heart attack. Low levels of troponin are also present in the blood stream of healthy individuals and can be detected by high-sensitive troponin tests. The SpinChip hs-cTnI test is a new high-sensitive test for measuring the amount of cardiac troponin I in the bloodstream as an aid in the diagnosis of heart attack. The purpose of this study is to determine the upper reference limits (URLs) for the SpinChip hs-cTnI test in a healthy population.
