Creatine Kinase Mb Normal Range U L
Ck levels are around 70 higher in healthy african americans compared to people of european descent.
Creatine kinase mb normal range u l. For females normal levels of creatine kinase range between 90 to 140 units per liter u l of blood. Creatine kinase ck is a dimer of two non identical subunits b m. Creatine kinase ck is an enzyme found primarily in the brain skeletal muscles and heart. Normal reference values for serum ck mb range from 3 to 5 percentage of total ck or 5 to 25 iu l.
The ck enzyme is a dimer composed of subunits derived from. A significant concentration of ck mb isoenzyme is found almost exclusively in the myocardium and the appearance of elevated ck mb levels in serum is highly specific and sensitive for myocardial cell wall injury. Creatine kinase is an enzyme found in the heart brain skeletal muscle and other tissues. Creatine kinase a healthy result should fall into the range 24 204 u l 0 41 3 47 µkat l or 24 00 204 00 iu l.
Background synopsis. Physiologically when muscle contracts atp is converted to adenosine diphosphate adp and ck catalyzes the rephosphorylation of adp to atp using creatine phosphate as the phosphorylation reservoir. Conditions that cause damage to any of these three areas produce an elevated level of ck. Normal ranges of creatine kinase are as follows.
The isoenzymes are ck mm ck bb and ck mb. For males normal levels of creatine kinase range between 38 to 174 units per liter u l of blood.
