This was fact checked by our expert Medical Review Board for accuracy and objectivity. about our editorial policy and review process. To detect and monitor muscle damage; to help diagnose conditions associated with muscle damage; for heart attack detection, this test has been largely replaced by troponin T and I — markers more specific to cardiac tissue; however, it may sometimes be used to help detect a second or subsequent heart attack see Common Questions 4.

Most test sent directly to you in days. However, you are currently at Lab Tests Online. Lab Tests Online is an award-winning patient education website offering information on laboratory tests. The content on the site, which has been reviewed by laboratory scientists and other medical professionals, provides general explanations of what might mean for each test listed on the site, such as what a high or low value might suggest to your healthcare practitioner about your health or medical condition.
The reference ranges for your tests can be found on your laboratory report. They are typically found to the right of your. If you do not have your lab report, consult your healthcare provider or the laboratory that performed the test s to obtain the reference range. Laboratory test are not meaningful by themselves. Their meaning comes from comparison to reference ranges. Reference ranges are the values expected for a healthy person. By comparing your test with reference values, you and your healthcare provider can see if any of your test fall outside the range of expected values.
Values that are outside expected ranges can provide clues to help identify possible conditions or diseases. While accuracy of laboratory testing has ificantly evolved over the past few decades, some lab-to-lab variability can occur due to differences in testing equipment, chemical reagents, and techniques. This is a reason why so few reference ranges are provided on this site.
Creatine kinase CK is an enzyme found in the heart, brain, skeletal muscle, and other tissues. Increased amounts of CK are released into the blood when there is muscle damage. This test measures the amount of creatine kinase in the blood. The small amount of CK that is normally in the blood comes primarily from skeletal muscles. For example, strenuous exercise and inflammation of muscles, called myositis, can increase CK as can muscle diseases myopathies such as muscular dystrophy. Rhabdomyolysis, an extreme breakdown of skeletal muscle tissue, is associated with ificantly elevated levels of CK.
A creatine kinase CK test may be used to detect inflammation of muscles myositis or muscle damage due to muscle disorders myopathies such as muscular dystrophy or to help diagnose rhabdomyolysis if a person has s and symptoms. CK may be ordered along with other blood chemistry tests such as electrolytesBUN or creatinine to evaluate kidney function. A urine myoglobin may also be ordered. A person may have muscle injury with few or nonspecific symptoms, such as weakness, fever, and nausea, that may also be seen with a variety of other conditions.
A healthcare practitioner may use a CK test to help detect muscle damage in these cases, especially if someone is taking a drug such as a statinusing ethanol or cocaine, or has been exposed to a known toxin that has been linked with potential muscle damage. In those who have experienced physical trauma, a CK test may sometimes be used to evaluate and monitor muscle damage. A series of CK tests may be used to monitor muscle damage to see if it resolves or continues. If a CK is elevated and the location of the muscle damage is unclear, then a healthcare practitioner may order CK isoenzymes or a CK-MB as follow-up tests, to distinguish between the three types isoenzymes of CK: CK-MB found primarily in heart muscleCK-MM found primarily in skeletal muscleand CK-BB found primarily in the brain; when present in the blood, it is primarily from smooth muscles, including those in intestines, uterus or placenta.
The CK test was once one of the primary tests ordered to help diagnose a heart attackbut in the U. However, the CK test may sometimes be used to help detect a second heart attack that occurs shortly after the first. For more, see Common Questions 4. A CK test may be ordered when muscle damage is suspected and at regular intervals to monitor for continued damage. It may be ordered when a muscle disease myopathy such as muscular dystrophy is suspected or when someone has experienced physical trauma, such as crushing injuries or extensive burns.
The test may be ordered when a person has symptoms associated with muscle injury such as:. Testing may be ordered when a person has nonspecific symptoms, especially when taking a drug or after an exposure to a substance that has been linked with potential muscle damage.
A high CK, or a rise in levels in subsequent samples, generally indicates that there has been some recent muscle damage but will not indicate its location or cause. Serial test that peak and then begin to drop indicate that new muscle damage has diminished, while increasing and persistent elevations suggest continued damage.
Increased CK levels may be seen in some muscular disorders myopathieswhich have a wide variety of causes. People may have CK levels that are ificantly to greatly increased, depending upon the severity of muscle damage. Those who have rhabdomyolysis may have CK levels that are times normal levels and occasionally even higher.
Normal CK levels may indicate that there has not been muscle damage or that it occurred several days prior to testing. Moderately increased CK levels may be seen following strenuous exercise such as in weight lifting, contact sports, or long exercise sessions. A low CK I need someone to take care of my ck may be seen in early pregnancy. Rhabdomyolysis is the rapid breakdown of muscle tissue. This condition can be caused by serious physical, chemical, or biological injury to muscles. Examples of causes include:. Complications can result from the rapid release of cell contents into the blood.
This has been known to cause damage to kidneys acute kidney injury, AKI and disseminated intravascular coagulation DIC. Once diagnosed and depending on the extent of injury, a person with rhabdomyolysis may be treated with intravenous fluids and other supportive care as well as procedures used to protect organs e. Muscle pain and weakness are common symptoms that are seen with many temporary conditions.
General, routine CK testing is usually not required. CK levels are a reflection of muscle damage. Temporary increases are seen with strenuous exercise but are not typically a concern unless severe or combined with extreme heat or humidity. You should not, however, stop taking a medication without first consulting with your healthcare provider. Increases in CK that are due to an underlying disease, such as uncontrolled diabetes or hypothyroidismmay resolve by controlling the condition.
A series of CK tests may be used to monitor heart damage to see if it resolves or continues. The heart damage that occurs during a heart attack can cause increased CK levels within a few hours. Levels peak within 12 to 24 hours and then return to normal within 2 to 4 days. If additional damage occurs or it is ongoing, such as during a second or subsequent heart attack, then CK levels may stay elevated.
Sometimes, the CK test may be ordered when a heart attack is suspected and a troponin test is not available. In this case, when CK is elevated, a CK-MB test may be used as a follow-up test to determine whether the increase is due to heart damage or skeletal muscle damage. Chest pain and increased CK levels plus elevated CK-MB indicate that it is likely that a person has recently had a heart attack. It provides a common language to unambiguously identify things you can measure or observe that enables the exchange and aggregation of clinical for care delivery, outcomes management, and research.
