Creatine Kinase Mb Normal Range U L

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 mb normal range u l. Ck levels are around 70 higher in healthy african americans compared to people of european descent. The upper normal limit for men is anywhere from 200 to 395 u l 3 4 6 8 ukat l and for women it s up to 207 u l 3 52 ukat l 3 4 5. 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. 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. The isoenzymes are ck mm ck bb and ck mb. Normal ranges of creatine kinase are as follows. Creatine kinase is an enzyme found in the heart brain skeletal muscle and other tissues.

For females normal levels of creatine kinase range between 90 to 140 units per liter u l of blood. 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. Creatine kinase mb enzopak last update 04 2014 single step method reagent kit for quantitative estimation of creatine kinase mb activity in serum. For males normal levels of creatine kinase range between 38 to 174 units per liter u l of blood.

Creatine kinase ck is an enzyme that catalyzes the reversible phosphorylation of creatine cr by adenosine triphosphate atp. Background synopsis.
