【SUMMARY】
Creatine Kinase MB (CK-MB) is an enzyme 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 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. CK-MB is one of the most important
cardiac markers and is widely recognized as the traditional marker for the
diagnosis of MI.
The CK-MB Rapid Test Cassette (Whole Blood/Serum/Plasma) is a simple test that
utilizes a combination of antibody coated particles and capture reagents to
qualitatively detect CK-MB in whole blood, serum or plasma. The minimum
detection level is 5 ng/mL CK-MB.
【DIRECTIONS
FOR USE】
Allow the test, specimen, buffer and/or controls to reach room
temperature (15-30°C) prior to testing.
1. Bring the pouch to room temperature before opening it. Remove the test
cassette from the sealed pouch and use it as soon as possible.
2. Place the cassette on a clean and level surface.
For Serum or Plasma specimen:
· Hold the dropper vertically and transfer 2 drops of serum or plasma
(approximately 50 µL) to the specimen area, then add 1 drop of buffer
(approximately 40 µL), and start the timer. See illustration below.
For Venipuncture Whole Blood specimen:
· Hold the dropper vertically and transfer 3 drops of whole blood
(approximately 75 µL) to the specimen area, then add 1 drop of buffer
(approximately 40 µL), and start the timer. See illustration below.
For Fingerstick Whole Blood specimen:
· To use a capillary tube: Fill the capillary tube and transfer approximately
75 µL of fingerstick whole blood specimen to the specimen area of test
cassette, then add 1 drop of buffer (approximately 40 µL) and start the timer.
See illustration below.
· To use hanging drops: Allow 3 hanging drops of fingerstick whole blood
specimen (approximately 75 µL) to fall into the specimen area of test cassette,
then add 1 drop of buffer (approximately 40 µL ) and start the timer. See
illustration below.
3. Wait for the colored line(s) to appear. Read results at 10 minutes. Do not interpret the result after 20 minutes.
