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
Probably normal: Creatine kinase (CK), also known as creatine phosphokinase (CPK) is an enzyme made by muscle tissues, including the heart muscle. Doctors most often are concerned with high levels of CK, which may indicate muscle damage. "Normal range" varies by laboratory, but a level of 49 is probably within the normal range of most laboratories. ...Read more
Not much: You are probably not having a heart attack, some illness that seriously damages your muscles, and are also probably not in heavy athletic training or doing really hard manual work. We have a saying in pathology, "look at the person, not the numbers." hope all else is okay, thanks for writing. ...Read moreSee 1 more doctor answer
I'm 25 yrs old. After lifting heavy my creatine kinase levels were 1800. When i don't exercise theyre normal. Is this ck normal for young adults?
Good for you: From time to time, i've run ck's on classes of students. The bodybuilders, after lifting, can run as high as 3000. ...Read more
Here's accurate info: Somebody's kidding you or there is a misunderstanding. Creatine kinase is an enzyme found in the blood; the reference range was determined for couch potatoes, and in my series' of athletic medical students, a majority of healthy young people have "elevated levels" just from exercising. It's also high in a few illnesses your physician knows about, but not from "nerves". ...Read more
Yes and no: Creatine kinase is meaningful only if the number is way-high and there's reason to worry about rhabdomyolysis, heart attack, carrying muscular dystrophy, or a few others. Most folk who exercise heavily have creatine kinases above the "reference range", which is just the lab's number for most ordinary folks who aren't actually sick. Don't look at numbers; look at your health -- why not go run? ...Read more
I am a 41 yr old female.My serum creatine kinase level is 257.Is there anything to be worried about?
Probably not: 257 isn't very high (it goes into the thousands with muscle injury) and tens of thousands when it's especially serious. Different labs have different cut-offs but i assume 257 is a little high in your lab? Simple muscular work can raise it. If you had a heart problem or muscle injury from statins, you'd have symptoms - are you feeling ok? It's always better to treat patients, not lab numbers. ...Read more
Take it easy: Any muscle injury due to trauma will results in increase muscle enzyme called cpk. If there is severe crush injury or large area of muscle involved, that may cause high amount of CPK release into blood, which will then cause some acute damage to kidneys. Said that, you had "small injury to calf muscle". Therefore, the amount of CPK in blood should not give you any problems. Good luck ! ...Read moreSee 2 more doctor answers
