Ck Lab Values. Creatine n phosphotransferase ec 2 7 3 2 in serum has been observed in a variety of clinical conditions subnormal activity may be found as a consequence of diminished efflux of the muscle enzyme into serum from reduced physical activity caused by illness or advanced age or may result from reduced muscle mass accompanying muscle wasting or. Ck mm is 7 to 12 times increased than the normal value. If someone had a stent placed or especially a cabg their troponin will be expected be elevated from the irritation within the heart. The three isoenzymes are ck mb cardiac ck mm skeletal and ck bb brain.
Subnormal activity of creatine kinase ck atp. Those who have rhabdomyolysis may have ck levels that are 100 times normal levels and occasionally even higher. A small amount of ck in the blood is normal. Depending on the type and level of ck found it can mean you have damage or disease of the skeletal muscles heart or brain. If it has been 48 hrs an elevated ck mb could indicate further myocardial injury. Several different factors contribute to high creatine kinase levels such as alcohol consumption strenuous exercise and or prescribed medications.
Subnormal activity of creatine kinase ck atp.
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. The three isoenzymes are ck mb cardiac ck mm skeletal and ck bb brain. Those who have rhabdomyolysis may have ck levels that are 100 times normal levels and occasionally even higher. Low creatine kinase levels causes of low creatine kinase levels 1 low muscle mass. Return to normal within 48 hours. Creatine kinase levels can be significantly reduced in autoimmune diseases such as.
