Detecting the macro forms of creatine kinase (CK)


Identifying the source of a CK elevation

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Test IDReporting NameAvailable SeparatelyAlways Performed
CKCreatine Kinase (CK), SYesYes
CKERCK Isoenzyme Elec, Specimen OnlyNoYes

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

CKECK Isoenzyme Electrophoresis, SNoNo

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

Testing begins with total creatine kinase analysis (CK). If the total CK activity is below 100 U/L, testing is complete.


If total CK activity is 100 U/L or greater, then isoenzyme electrophoresis (CKE) will be performed at an additional charge.

Method Name A short description of the method used to perform the test

CK: Photometric, Creatine Phosphate + ADP

CKE: Electrophoresis, Densitometry

NY State Available Indicates the status of NY State approval and if the test is orderable for NY State clients.


Reporting Name Lists a shorter or abbreviated version of the Published Name for a test
