Creatine kinase (CK) is a blood test that measures the amount of the enzyme creatine kinase in your blood. CK is found in various muscles throughout the body, including the heart and skeletal muscles. High levels of CK can indicate muscle damage or stress.

The provider incises the shoulder joint to inspect the interior, drain any fluid, and or remove any debris due to recurrent dislocations or traumatic injury.

The CK test provides valuable information regarding muscle damage or stress, helping to diagnose and monitor conditions like heart attacks and muscular diseases. Results are typically available within a few hours to a day.

Generally, no special preparation is required for a CK test. However, patients may be advised to avoid strenuous exercise before the test to prevent artificially high CK levels. It's important to inform the healthcare provider about all medications, as some drugs can affect CK levels.

During the blood draw, patients might feel a slight pinch or sting when the needle is inserted. There might be mild discomfort or bruising at the site afterward. Most patients find the procedure quick and straightforward, with minimal pain or complications.

Alternative diagnostic tests might include Troponin tests (for heart conditions), Myoglobin blood tests, or imaging studies such as MRI or CT scans to visualize muscle damage. Each alternative has its pros and cons and may be chosen based on the specific situation.

A phlebotomist or a nurse usually performs the blood draw. The test is then analyzed by a medical laboratory technologist or clinical pathologist.

The CK test is used to diagnose conditions that cause muscle damage. This can include heart attacks, muscular dystrophy, rhabdomyolysis, and other diseases that affect muscle tissue. The goal is to detect and monitor muscle damage, informing appropriate treatment strategies.

Post-procedure care is minimal. Patients can usually resume normal activities immediately unless they experience dizziness or discomfort, in which case they should rest briefly. Keep the puncture site clean to prevent infection.

The CK test is indicated for patients experiencing symptoms like severe muscle pain, weakness, or muscle inflammation. It's also used when a heart attack is suspected, and in diagnosing conditions like rhabdomyolysis or muscular dystrophy.
