Is CK and CPK the same lab test?

Creatine Kinase (also known as CK, or Creatine Phosphokinase [CPK]) is an important diagnostic blood test for myopathies. CK is a type of protein called an enzyme that is especially active in skeletal muscle, heart tissue, and the brain.

What is the difference between CK and CPK?

Creatine kinase (CK), also known as creatine phosphokinase (CPK) or phosphocreatine kinase, is an enzyme (EC 2.7. 3.2) expressed by various tissues and cell types. This CK enzyme reaction is reversible and thus ATP can be generated from PCr and ADP.

What is CK M?

Creatine kinase-MB (CK-MB) is a form of an enzyme found primarily in heart muscle cells. This test measures CK-MB in the blood. CK-MB is one of three forms (isoenzymes) of the enzyme creatine kinase (CK). These isoenzymes include: CK-MM (found in skeletal muscles and the heart)

What does CK-BB stand for?

Creatine kinase
Definition. Creatine kinase is an enzyme consisting of three major isoenzymes, CK-BB (brain), CK-MB (heart), and CK-MM (skeletal muscle).

What are the different types of creatine kinase?

Types of Creatine Kinase: The enzyme creatine kinase (CK) is found to predominantly exist as two subunits, namely, B-brain type and M-muscle type. This leads to the formation of three isoenzymes- CK-MM, CK-MB and CK-BB. Different chromosomes are found to hold the genes for these subunits; the M subunit on 19q13 while the B subunit is on 14q32.

What is a creatine kinase ( CK ) test?

What is a creatine kinase (CK) test? This test measures the amount of creatine kinase (CK) in the blood. CK is a type of protein, known as an enzyme. It is mostly found in your skeletal muscles and heart, with lesser amounts in the brain. Skeletal muscles are the muscles attached to your skeleton. They work with your bones to help you move

What do B and M stand for in creatine kinase?

The B and M stand respectively for “brain” and “muscle.” Three isoenzymes of creatine kinase are recognized, CK-MM, CK-BB and CK-MB; these are formed from the basic B and M type of creatine kinase. In addition, a third category, mitochondrial creatine kinase, has at least two subcategories.

What is the normal range of serum creatine kinase?

It performs this function in all kinds of muscles, not just the skeletal muscles responsible for voluntary motion, but also the smooth muscles that power the digestive system and the heart muscle. It also provides the basic energy source for the brain. The normal range of serum creatine kinase is between 10 and 120 micrograms per liter of blood.
