Muscle injury: CPK or creatinine phosphokinase, is an enzyme found in 3 "flavors"- isoforms- found in the brain, muscle and heart that is released when the respective organ is damaged. Normal upper limit of nl depends on the lab, but generally is 120mcg/l. Elevation may be caused by numerous perturbations: heart attack; seizures; muscle damage; heavy exercise; hyperthyroidism; hypothyroidism; brain injury etc. ...Read more
Creatine kinase is an enzyme found in muscles throughout the body. There are different subtypes of the enzyme, called isoforms, which predominate in different organs. For instance, the isoform in skeletal muscles is different from that which is most heavily found in the heart muscle. A blood tests detects levels of this in the body, for example if ...Read more
That's too long: It does down in 48-72 hours. If it's elevated after 3 weeks, there is on-going injury or you have a rare variant called "macro cpk" in which it is always elevated but normal (ie, not indicative of injury). The pattern and level are important. Slight elevations have no clinical significance. CPK iso-enzymes can help determine the source. Your doctor is the best one to make this evaluation. ...Read more
Muscle enzyme: CPK elevations are seen in muscle disease, acute cardiac events, muscle trauma (rhabdomyolysis) but also, in weight lifters, and marathon runners. So, can be rather serious or benign. Perhaps, a severe localized cramp could cause enough muscle trauma to raise the level modestly, but, if significantly up, need to test further and uncover the etiology. ...Read more
Cpk level 856. I did pt for 3 days rested 3 days and did 1 day of pt and the next day i had my levels checked. Could this be the reason they are high?
Of course: The reference range is set for people who do not exercise. When i've tested medical students, essentially everybody who exercises strenuously is above "normal", with values up to 5000 in one guy who'd just spent a weekend cutting and hauling lumber and 3000 in a guy who'd just done 450 lb squats for 45 minutes. Stop worrying about this. ...Read more
My CPK level on blood work was 93. Is that high or normal? Mb-cpk was 0.9. And troponin 1 was 0.01
My CPK level is 209 in the morning after Workout done for muscle training in the evening. Is it normal?
It isn't that high: well.... if it were all coming from the heart muscle that would be bad....otherwise, that isn't a very high number. Many people who have big muscles always have that level. I've looked at hundreds of articles on exercise physiology and while literally muscle damage is considered by many a stimulant for muscle growth, haven't seen CPK's as predictive of growth. Not bad; can't say if actually good ...Read more
CPK: Hi, Ck or CPK is found in striated muscle, heart tissue, and brain, damage to either can increase the level in blood, also thyroid imbalance could increase CK due to muscle damage, CK clearance from body decreases in kidney disease. Your level is mildly elevated which could be 2/2 exercise, trauma to muscle, accident. ...Read moreSee 1 more doctor answer
