February is recognized as Heart Month, an important time to raise awareness about cardiovascular diseases, their risks, and the importance of early detection. Heart disease remains the leading cause of death globally, making timely and accurate diagnostics essential.
One of the most critical biomarkers for myocardial injury is cardiac troponin I (cTnI). The hscTnI Rapid Test Kit (FIA) by Vitrosens Biyoteknoloji offers a fast, accurate, and reliable method for detecting high-sensitivity cardiac troponin I (hscTnI) in serum, plasma, or whole blood.
Understanding Cardiac Troponin I (cTnI) and Its Importance
Troponins are regulatory proteins found in heart muscle cells, playing a crucial role in muscle contraction. The troponin complex consists of three subunits:
- Troponin I (cTnI)
- Troponin T (cTnT)
- Troponin C (cTnC)
When the heart muscle is damaged as in the case of acute myocardial infarction (AMI) or heart attack cTnI is released into the bloodstream.
hscTnI is highly specific to heart muscle injury, making it a crucial biomarker for detecting myocardial infarction. It becomes detectable in the blood within 4-6 hours of cardiac damage and remains elevated for 6-10 days, providing a longer diagnostic window for accurate assessment. Due to its high sensitivity and specificity, measuring hscTnI levels is considered the gold standard for diagnosing heart attacks and myocardial injury.
Why Choose the hscTnI Rapid Test Kit (FIA)?
The hscTnI Rapid Test Kit (FIA) is a fluorescence immunoassay (FIA) test designed for the quantitative detection of cTnI in serum, plasma, and whole blood samples.
Key Features & Benefits
- High Sensitivity & Specificity
- Fast Results – Provides accurate results within 15 minutes
- Easy-to-Use – Requires minimal training and no complex lab equipment
- Applicable for Whole Blood, Serum, and Plasma
- Reliable Storage – Stable at 2-30°C for 24 months
- Compatible with Vitrosens Immunofluorescence Analyzer
These features make the hscTnI Rapid Test Kit (FIA) an essential tool for early cardiac risk assessment in emergency rooms, clinics, and critical care units.
How Does the hscTnI Rapid Test Work?
The hscTnI Rapid Test Kit (FIA) utilizes a double antibody sandwich immunoassay combined with fluorescent immunochromatography for precise quantification of cTnI levels.
Step-by-Step Test Procedure
- Prepare the Sample – Collect serum, plasma, or whole blood.
- Mix with Reagent – Add 100 µL of the sample and 100 µL of sample diluent to the freeze-dried powder.
- Incubate & Mix – Pipette the mixture for 60 seconds for proper dissolution.
- Load the Test Cassette – Transfer 100 µL of the mixture into the sample well.
- Analyze – Insert the test cassette into the immunofluorescence analyzer and get esults in 15 minutes.
- Quick Test Mode – Manually let the test develop for 15 minutes before inserting it into the device.
Interpreting the Test Results
The hscTnI Rapid Test Kit (FIA) provides quantitative results for cardiac troponin I levels.
Reference Ranges:
Gender |
Normal Range (ng/mL) |
Elevated Levels (Risk of AMI) |
Male |
0 – 0.034 |
≥0.034 |
Female |
0 – 0.016 |
≥0.016 |
Clinical Significance:
- Elevated hscTnI levels suggest myocardial infarction risk
- Results should be used alongside clinical symptoms and ECG findings
Important Note:
hscTnI levels peak 12-16 hours after cardiac injury and can remain elevated for 6-10 days, making repeat testing essential for monitoring patient progress.
The Role of hscTnI Testing During Heart Month
February is Heart Month, a time dedicated to raising awareness about cardiovascular health. Given that 1 in 4 deaths is due to heart disease, early detection tools like the hscTnI Rapid Test Kit (FIA) are crucial for saving lives.
Why is early testing important?
- Helps detect silent heart attacks
- Allows timely intervention and treatment
- Assists in cardiac risk assessment for at-risk individuals
This Heart Month, healthcare professionals should prioritize rapid and reliable testing for heart disease prevention.
The hscTnI Rapid Test Kit (FIA) is an indispensable tool for detecting cardiac troponin I levels quickly and accurately. Whether used in emergency settings or routine cardiac screenings, this test plays a vital role in early myocardial infarction detection, ultimately improving patient outcomes.
