If CK-MB is elevated and the ratio of CK-MB to total CK (relative index) is more than 2.5-3, then it is likely that the heart was damaged. A high CK with a relative index below this value suggests that skeletal muscles were damaged. (For more, see Common Questions #3.) ...
After the first urine specimens, representing concentrated and acidified visible components (such as blood cells, epithelial cells, tubular) easy to observe the relative concentration. Random urine that is a random urine specimens convenient, but by diet, ...
We compared the predictive properties of an initial absolute creatine kinase-MB (CK-MB) to creatine kinase-MB relative index (CK-MB RI) for detecting acute myocardial infarction (AMI), acute coronary syndromes (ACS), and serious cardiac events (SCE). Consecutive patients > 24 years of age ...
(due to skeletal muscle injury), the measurement of CK-MB as a percentage of total CK has been used to calculate relative index. A CK-MB to CK ratio of > 6% is reported to be specific for myocardial injury, whereas a ratio of < 6% is consistent with skeletal muscle damage or non-...
The measurements of CK, myoglobin (threshold of 90 μg/l), CK-MB (threshold of 7 ng/ml and 3 relative index 30 °C) modulated by an algorithm, were efficient to rule out acute myocardial infarction (AMI). Their specificity was too low to confirm the diagnosis. Our findings were in ...
