There are several cardiac markers that can be used for acute myocardial infarction (AMI) diagnosis, such as CK-MB, Myoglobin, Troponin I, CRP, FABP and IMA. Amid the acute infarct, the timeline of elevated level of cardiac markers in blood is as follows:
Myoglobin (1hr) → cTnI / cTnT (4hr) → CK-MB (4hr) → FABP (6hr) → CRP (14hr) → LD-1 (24hr).
The Firstep Cardiac Marker Test is a sandwich immunochromatographic assay, it detects cardiac markers in blood qualitatively for preliminary screening. This test should not be used as the sole criteria for the diagnosis of acute myocardial infarction, in suspected case further confirmation shall be made by physician.

Scope of application
Patients suspected of having Acute Myocardial Infarction.
Cardiac Troponin-I (cTnI) is a cardiac muscle protein, together with troponin T (TnT) forms complex in heart to play a fundamental role in the transmission of intracellular calcium signal actin-myosin interaction. The human cTnI has an additional amino acid residues on its N-terminal that are not exist on the skeletal forms thus making cTnI a specific marker for indicating cardiac infarction.
Cardiac Troponin-I Rapid Test is an immunochromatography based one step in vitro test. It is designed for qualitative determination of cardiac Troponin-I (cTnI) in human Whole Blood/Plasma/Serum specimens as an aid in the diagnosis of myocardial infarction.
