CK-BB details
Description
CK-BB is one of three tissue-specific forms (isoenzymes) of creatine kinase, an enzyme involved in energy production, and this particular form is found predominantly in brain tissue, with smaller amounts in the lungs, GI tract, and other organs. It's the least commonly used of the CK isoenzymes clinically, since brain-related conditions are now typically evaluated with more specific and useful tests (like imaging or specific brain injury markers) rather than CK-BB levels, which aren't very sensitive or specific for brain injury on their own. Historically it was studied as a possible marker after significant brain trauma or stroke, but this isn't standard clinical practice today.

Creatine Kinase Isoenzymes
$48.99
The Creatine Kinase Isoenzymes test is used to confirm or rule out the diagnosis of acute myocardial infarction, assess its severity, and monitor the patient's condition.
- CK-BB A form (isoenzyme) of creatine kinase found mainly in brain tissue. Less commonly used clinically than the heart- and muscle-specific forms.
- CK-MB A form of creatine kinase found mainly in heart muscle. Historically used to help detect heart muscle damage, such as a heart attack.
- CK-MM A form of creatine kinase found mainly in skeletal muscle. Elevated levels typically reflect muscle injury or strenuous exercise rather than heart damage.
- Creatine Kinase An enzyme found in muscle, heart, and brain tissue. Elevated levels typically indicate muscle damage, from injury, intense exercise, or certain medical conditions.
- Macro CK Type 1 A less common, larger form of creatine kinase bound to an antibody. Usually a benign finding rather than a sign of tissue damage, but can cause a persistently elevated CK result.
- Macro CK Type 2 A less common, larger form of creatine kinase, typically seen in people who are critically ill; unlike Type 1, it can reflect a more serious underlying condition.
Creatine Kinase Isoenzymes (CK Isoenzymes) with Total CK
$28.49
This test measures creatine kinase (CK), an enzyme found primarily in striated muscle and heart tissue, and may be useful in assessing muscle damage. Total CK and fractions of CK isoenzymes are reported. CK is a dimeric enzyme composed of either 2 B subunits (CK-BB), 2 M subunits (CK-MM), or an M and a B subunit (CK-MB). CK-MM is the primary isoenzyme found in the skeletal muscle and heart tissue. CK-BB is mainly found in the brain and smooth muscle of gastrointestinal tract and urinary bladder. CK-MB is mainly found in the heart with a small amount in skeletal muscle [1].
