Cardiac Markers Combo Rapid Test Troponin I Myoglobin CKMB 3 in 1 Cassette Combo
INTENDED USE
The Cardiac Markers Combo Rapid Test Cassette (Whole Blood/Serum/Plasma) is a rapid visual immunoassay for the qualitative presumptive detection of human Myoglobin, CK-MB and cardiac Troponin I in whole blood, serum or plasma. This kit is intended for use as an aid in the diagnosis of myocardial infarction (MI).
INTRODUCTION
Myoglobin (MYO), Creatine Kinase MB (CK-MB) and cardiac Troponin I (cTnI) are proteins released into the bloodstream after cardiac injury. Myoglobin is a heme-protein normally found in skeletal and cardiac muscle with a molecular weight of 17.8 kDa. It constitutes about 2 percent of total muscle protein and is responsible for transporting oxygen within muscle cells. When muscle cells are damaged, Myoglobin is released into the blood rapidly due to its relatively small size. The level of Myoglobin increases measurably above baseline within 2-4 hours post-infarct, peaking at 9-12 hours, and returning to baseline within 24-36 hours. CK-MB is an enzyme also present in the cardiac muscle, with a molecular weight of 87.0 kDa. Creatine Kinase is a dimeric molecule formed from two subunits designated as “M” and “B”, which combine to form three different isoenzymes, CK-MM, CK-BB and CK MB. CK MB is the isoenzyme of Creatine Kinase most involved in the metabolism of cardiac muscle tissue. The release of CK-MB into the blood following an MI can be detected within 3-8 hours after the onset of symptoms. It peaks within 9 to 30 hours, and returns to baseline levels within 48 to 72 hours. Cardiac Troponin I is a protein found in cardiac muscle, with a molecular weight of 22.5 kDa. Troponin I is part of a three subunit complex comprised of Troponin T and Troponin C. Along with tropomyosin, this structural complex forms the main component that regulates the calcium sensitive ATPase activity of actomyosin in striated skeletal and cardiac muscle. After cardiac injury occurs, Troponin I is released into the blood 4-6 hours after the onset of pain. The release pattern of Troponin I is similar to CK-MB, but while CK-MB levels return to normal after 72 hours, Troponin I remains elevated for 6-10 days, thus providing for a longer window of detection for cardiac injury.

MAIN CONTENTS
• One pouch containing a reaction test Cassette with desiccant.
• Disposable pipettes.
• Buffer.
• Instructions for use.
STORAGE AND STABILITY
• Store at 39~ 86 º F (4 ~ 30 º C) in the sealed pouch for 18 months.
PRECAUTIONS
• For in vitro diagnostic use only.
• Do not use after expiration date.
• The test Cassette should remain in the sealed pouch until use.
• The used test Cassette should be discarded according to local regulations.
DIRECTION OF USE
Bring tests, specimens, buffer and/or controls to room temperature (15-30°C) before use.
- Remove the test from its sealed pouch and use it as soon as possible. For best results, the assay should be performed within one hour.
- Place the test device on a clean and level surface.
For Serum or Plasma specimens: Hold the dropper vertically and transfer 2 drops of serum or plasma (approximately 50 mL) to the specimen well (S) of the test device, then start the timer. See illustration below.
Hold the strip by the end, where the product name is printed. To avoid contamination, do not touch the strip membrane.
OR
Transfer 3 drops of whole blood specimen (approximately 75 µL) to the specimen well of the device with the provided disposable pipette, then add 1 drop of buffer and start the timer.
OR
Allow 3 hanging drops of fingerstick whole blood specimen to fall into the center of the specimen well (S) on the device, then add 1 drop of buffer and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result area.
As the test begins to work, color will migrate across the membrane.
- Wait for the colored band(s) to appear. The result should be read at 10 minutes. Do not interpret the result after 20 minutes.
INTERPRETATION
