Determining the upper limits for a new heart attack test

Determination of the 99th Percentile Upper Reference Limits (URLs) for the SpinChip High Sensitivity Cardiac Troponin I (SpinChip Hs-cTnI) Test

SpinChip Diagnostics ASA · NCT06463275

This study is testing a new quick blood test for heart attacks to see what normal troponin levels are in healthy people aged 18 to 80.

What this trial studies

This observational study aims to establish the upper reference limits (URLs) for the SpinChip high-sensitivity cardiac troponin I (hs-cTnI) test in a healthy population. The SpinChip hs-cTnI test is designed to measure troponin I levels in the bloodstream, which are critical for diagnosing acute myocardial infarction (AMI). By analyzing blood samples close to the patient, results can be obtained within 10 minutes, significantly faster than traditional laboratory methods. The study will involve healthy participants aged 18-80 who meet specific eligibility criteria, ensuring accurate reference values for this new diagnostic tool.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy individuals aged 18-80 with no known cardiovascular diseases.

Not a fit: Patients with existing cardiovascular conditions or those on treatments for hypertension or diabetes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to faster and more accurate diagnoses of heart attacks, improving patient outcomes.

How similar studies have performed: Other studies have successfully established reference limits for similar high-sensitivity troponin tests, indicating a promising approach.
