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.See 1 more doctor answer
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.See 1 more doctor answer
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.
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.
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?
Muscle source: A problem with your skeletal muscles (e.g., myositis) could be the cause of those findings. More specific tests are required.
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!
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".
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.
Muscle breakdown: Ck is a byproduct of muscle breakdown usually occurring from muscle injury or sometimes from certain supplements.
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.See 1 more doctor answer
