In summary, renal injury with high serum CPK values becomes a true concern when levels of CPK reach 5,000 IU/L and the patient has serious co-morbid disease such as volume depletion, sepsis or acidosis. Otherwise, values of up to 20,000 IU/L may be tolerated without untoward event.
- Continuing fluid as long as the CK is >5,000 U/L amounts to treating a lab abnormality, rather than a true disease.
- CK has a half-life of 36 hours. Thus, if the CK is markedly elevated, it will remain above 5,000 U/L for days – long after myoglobin is gone.( 28235546)

What are the limitations of standard reference ranges for serum CK levels?
The actual distribution of serum CK levels in a healthy population is markedly skewed toward higher values and is nongaussian. 1–3 A 97.5% normal threshold is associated with a much lower false-positive rate and is recommended by the European Federation of Neurological Societies (now the European Academy of Neurology). 4 This group also recommends pursuing further …

What is elevated CK?
But elevated CK sometimes is an incidental finding in a patient without muscle-related symptoms or with only minimal nonspecific muscle symptoms (eg, cramps, spasms, fatigue) that do not significantly interfere with activities of daily living. This condition is sometimes referred to as “asymptomatic hyper-CK-emia.”.
What causes elevated CK levels?
A patient with truly elevated levels should be evaluated for a variety of nonneuromuscular causes, including endocrine disorders, metabolic disturbances, drug effects, and malignancy.
What is macro CK type 1?
Macro CK type 1 is more common and is found in up to 1.2% of the general population: complexes are composed of CK and immunoglobulin and are associated with autoimmune diseases.9,15Macro CK type 2 complexes consist of CK and an undetermined protein and are associated with malignancies.
Can statins cause CK elevation?
Drugs commonly elevate CK. Prescription drugs and supplements are an important and common cause of CK elevation, so it is important to carefully review medications the patient is taking. Statinscan cause myalgia, muscle weakness, and rhabdomyolysis.
Can creatine kinase be reduced?
Creatine kinase levels can be significantly reduced in autoimmune diseases, such as lupus and rheumatoid arthritis [ 86, 87, 88, 89 ]. The more inflammation there is, the lower creatine kinase levels can get.
Is creatine kinase good for your heart?
Studies suggest that the more creatine kinase a person has within the normal range, the better their heart and muscles can function . In a study of 442 people, people with low creatine kinase levels were 73% more likely to faint [ 91 ].
What does creatine kinase do?
Creatine kinase is an important enzyme needed for energy production and muscle function. Athletes have more of this enzyme in their blood, but so do obese and overweight people. High levels can tell us if there is muscle, heart, or brain damage. Keep reading to learn more about this enzyme, what it means if your levels are high or low, ...
What causes creatine kinase to increase?
Creatine kinase will increase with muscle, heart, or brain damage – these can be caused by an underlying disease or disorder, including: Muscle injuries, physical trauma, and burns [ 20, 21, 22, 23, 24]
What does elevated creatine kinase mean?
Elevated creatine kinase can be a sign of serious tissue damage or an underlying disease or disorder. The most important thing is to work with your doctor to find out what’s causing your elevated creatine kinase and to treat any underlying condition!
Does exercise increase creatine kinase?
Studies suggest that after strenuous exercise, an increase in creatine kinase (muscle damage) can be attenuated by consuming enough carbs, protein, and antioxidants [ 82 ]. A small study with 14 men showed that sports massage 2 hours after exercise decrease CK levels [ 83 ].
Where is creatine kinase found?
Higher amounts of this enzyme are found in tissues that use a lot of energy, such as the muscles (including the heart) and the brain [ 1 ]. Creatine kinase will leak into the blood when these tissues are damaged.
What is CK test?
A CK test is most often used to diagnose and monitor muscular injuries and diseases. These diseases include: Muscular dystrophy, a rare inherited disease that causes weakness, breakdown, and loss of function of skeletal muscles. It mostly occurs in males. Rhabdomyolis, a rapid breakdown of muscle tissue.
What is CK in blood test?
This test measures the amount of creatine kinase (CK) in the blood. CK is a type of protein, known as an enzyme. It is mostly found in your skeletal muscles and heart, with lesser amounts in the brain. Skeletal muscles are the muscles attached to your skeleton. They work with your bones to help you move and give your body power and strength.
Where is CK found?
CK is a type of protein, known as an enzyme. It is mostly found in your skeletal muscles and heart , with lesser amounts in the brain. Skeletal muscles are the muscles attached to your skeleton. They work with your bones to help you move and give your body power and strength. Heart muscles pump blood in and out of the heart.
What does CK mean in blood?
There are three types of CK enzymes: A small amount of CK in the blood is normal. Higher amounts can mean a health problem. Depending on the type and level of CK found, it can mean you have damage or disease of the skeletal muscles, heart, or brain. Other names: CK, total CK, creatine phosphokinase, CPK.
How long does it take for CK to peak?
Balance problems. Numbness or tingling. You may also need this test if you had a muscle injury or stroke. CK levels may not peak until up to two days after certain injuries, so you may need to be tested a few times.
What are the muscles that help you move?
Skeletal muscles are the muscles attached to your skeleton. They work with your bones to help you move and give your body power and strength. Heart muscles pump blood in and out of the heart. There are three types of CK enzymes: A small amount of CK in the blood is normal. Higher amounts can mean a health problem.
How long does CK last?
CK levels usually peak within ~24-48 hours and then gradually decline. CK has a half-life of ~36 hours, whereas myoglobin has a half-life of ~2-4 hours ( 28235546). Serial CK values may be useful in some situations: Initial CK level is moderately elevated and there is a high index of suspicion for rhabdomyolysis.
How long does it take for CK to peak?
CK levels usually peak within ~24-48 hours and then gradually decline. CK has a half-life of ~36 hours, whereas myoglobin has a half-life of ~2-4 hours ( 28235546). Initial CK level is moderately elevated and there is a high index of suspicion for rhabdomyolysis. The initial CK level is 1,000-5,000 U/L.
What is rhabdomyolysis?
Rhabdomyolysis is a riddle wrapped in a mystery inside an enigma. The definition of rhabdomyolysis is debatable, specifically regarding which level of creatinine kinase (if any) predicts renal injury. There are precisely zero RCTs showing benefit of any treatment for rhabdomyolysis.
Does rhabdomyolysis increase creatinine?
Most studies of rhabdomyolysis have used creatinine levels to determine whether there is “renal failure.”. However, rhabdomyolysis may itself cause release of creatinine from myocytes and thereby directly increase the creatinine levels!
Can creatinine kinase be used to diagnose rhabdomyolysis?
Aside from creatinine kinase levels, three lab patterns may suggest rhabdomyolysis. None of these patterns are 100% sensitive , so they cannot be relied upon to diagnose rhabdomyolysis. However, if you happen to come across them, further investigation is warranted.
Is brownish urine a sign of rhabdomyolysis?
True signs of rhabdomyolysis:#N#Brownish urine (“tea-colored”) is generally described as being reported in 5-10% of cases ( 30630682) . However, this finding might be more noticeable among patients with foley catheters, in whom urine color is clinically apparent.
What are the symptoms of rhabdomyolysis?
Overall in the literature, symptoms of rhabdomyolysis are uncommon: ( 30617905) Muscle pain (23% of patients), swelling, or cramping. Muscle weakness (12% of patients). Muscle swelling. Symptoms are usually absent in critically ill patients (e.g., due to sedation or altered sensorium).
