You need to call whatever lab company this is and determine if they is a CK or a CKMB test. They put cardiac enzyme in parentheses. Which If that’s you ckmb, true cardiac CK, you’re in trouble. Heart attack trouble.
If that’s simply a CK Aand this lab company sucks? Total CK is more manipulative.
Either way. That’s a big fuck up on whatever lab company this is. Enough for me to make sure not to use them every again.
