Disease With High Levels Creatinine Kinase
Damage to muscle: The correct term is creatine kinase (ck). Creatinine is something else. Useful to know: most "muscle" weakness is actually caused by nerve, not muscle, malfunction. True muscle weakess: myocytes (muscle cells) contain lots of the enzyme ck. Low levels are found in blood normally. Damage to myocyte cell membranes from a variety of causes causes leakage of ck into the blood. Recovery->normalization. ...Read more
I have a blood value for creatinine kinase of 298 u/l. Is that unhealthy or is it normal when doing workouts a few times a week?
Creatinine kinase: This is okay as long as you don't have severe pain. Ck is considered significant when the value is 10 times upper limit of normal. ...Read more
Yes: Creatine kinase is a muscle enzyme that is measured to assess heart damage (the mb isoenzyme form) or skeletal muscle damage (the mm isoenzyme). Creatinine is an endogenous peptide, present in everyone, that is cleared by the kidneys and is measured in clinical practice to estimate kidney function. ...Read more
Bun is 28, creatinine 1.16. Egfr 61. Healthy 35 yr old caucasian female. Only problem is benign fasciculations x1 year. Normal creat kinase. Why?
Stop worrying: I am going to assume that you feel well and are asking why your estimated GFR is lowish and your BUN a bit high. I like to eat protein and my BUN is always high. Are you athletic? When I was lifting daily my creatinine was 1.6-1.7; or a Motrin tablet or minimal kidney disease may be raising yours. I suggest repeat in a year and stop fretting over a number in the meantime. ...Read more
Hi I had a blood test done and my creatinine kinase was at 235grams/litre and albumin 54grams/litre. Nil heart ischema. Curious to other probabilit?
Collar bone pain, swelling. X-ray, CT scan nl. Labs for sed rate, cpk, creatinine kinase, CBC all nl. Pcp, pain dr stumped. Any ideas or suggestions?
Do you lift weights?: If you lift weights (benchpress), that might be the culprit. The muscles and ligaments that attach to the collarbone are shown in the diagram. If your pain is at one of these places, you likely have a strain from lifting. If you've fallen on your outstretched arm, the same thing can happen. Also, ask your doctor about osteonecrosis (dying bone due to lack of blood supply). Hope that helps! ...Read more
Generally not: Unless an acute presentation.Get a more detailed answer ›
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
Just being fit: The reference range is set on the assumption that you don't exercise. Fitness types routinely have values way up in the thousands. No need to limit your fun in the gym. ...Read more
Hi I'm 17 and I'm a competitive swimmer sprinter, I recently did a blood work and the creatine kinase level was 470 u/l is that considered high?
Ck: It isn't unusual for ck to be elevated after vigorous workouts. ...Read more
Being athletic: The reference range for creatine kinase is set based on the assumption that you do not exercise. In my series of medical students, all the men and the majority of the women who lead even moderately fitness-focused lifestyles have high creatine kinase -- often very high. If you're healthy and are working your muscles, be proud of yourself and keep doing what you're doing. ...Read more
Depends on cause:
CPK levels are elevated due to injury to the muscles, it gets elevated with myocardial injury during heart attack and injury to the sleletal muscles as well. So it depends how much damage to the muscles is and the cause of the damage and responce to treatment of the underlying condition
it can take from few days to several days. ...Read more
Professional endurance athlete, trains 8+ hrs/day with b12, creatine kinase out of range high normally and gets sick very easily. Recently had epidura?
Normal: Sounds like a bit much of overtraining. Ck is normally elevated if high exercisers, esp if arican american. You seem to be overdoing it and even if u r a personal trainer, u need a coach. Hrs, md www. Thepmc. Org. ...Read more
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 more
CPK: Ck is a polycomponent muscle enzyme. The ck mb is the muscle-brain part of ck total. That is why the lower value for mb. The lab normals would tell whether these are elevated or not. Elevations are usually from muscle damage and the mb is found in heart. ...Read more
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 more
I'm 25 yrs old. After lifting heavy my creatine kinase levels were 1800. When I don't exercise they're 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
