Combined CTnI Myo CK-MB Rapid Test For Outpatient Emergency Clinical
Combined CTnI Myo CK-MB Rapid Test For Outpatient Emergency Clinical
CTnI/MYO/CK-MB Overview
The isoenzyme troponin I/myoglobin/creatine kinase (cTnI/Myo/CK-MB) includes the following three indicators: The combined detection of troponin I (cTnI), myoglobin (Myo) and creatine kinase isoenzyme (CK-MB) is of great importance for the Early diagnosis of acute myocardial diseases such as AMI
American Society for Clinical Biochemistry ( NACB ) Practice Guide
Signs of myocardial necrosis should be detected in all patients with ACS
Troponin is a key marker in the diagnosis of myocardial infarction
Myoglobin binding specific markers of myocardial necrosis (eg, cTnI/CK-MB) may help clear or diagnose myocardial infarction more quickly.

CTnI/MYO/CK-MB Clinical Significance
- This is for the initial and strategic diagnosis of corneal syndrome risk
- Defining the area of myocardial infarction
- Different diagnosis of different causes of chest pain
- Beware of myocardial injury for a variety of reasons
- Evaluation of clinical evidence of some medical drugs
| Possibility of outcome | |||
| cTnI | CK-MB | MYO | Clinical possibility |
|
+ |
+ | + | Myocardial infarction / myocardial injury can basically be diagnosed and the time of onset is 12-24 hours. |
| + | + | - | It can basically be diagnosed as a myocardial infarction injury / myocardial infarction injury, and the detection time is more than one day that has passed during the myocardial identification window. |
| + | - | - | Myocardial damage occurs for a few days and should be rechecked in a few hours. |
| + | - | + | In patients with hepatic myocardial injury, symptoms may last for more than three days, and in patients with re-injury or necrotic areas due to blood clots. |
| - | + | + | In early myocardial ischemia, liver myocardial injury following monitoring of CTNI in 4-8 hours is recommended. |
|
- |
- | + | It is recommended to check CTNN in 4-8 hours. |
| The reserves can be caused by other diseases such as creative work, musculoskeletal injuries, and liver and kidney disease. | |||
| - | + | - | For minor myocardial injury, we recommend CT monitoring in 4-8 hours. |
| It may not be myocardial injury and the test time was through my window. | |||
|
- |
- | - | The possibility of ischemic myocardial injury is generally ruled out. When in doubt, it is recommended to check every two to four hours. |
