Comments
Guide for use:
CODE 8888 if test for CK was not done for this hospital presentation.
Where possible, several CK measures should be recorded and their associated date and time. At a minimum, an initial, peak and late value should be recorded.
When only one CK level is recorded, this should be the peak level.
Comments:
Elevation of CK isoenzyme is an indication of damage to muscle.
There are three different CK isoenzyme sub-forms:
- CK-MM (skeletal muscle)
- CK-MB (cardiac muscle)
- CK-BB (brain tissue)
