phosphocreatine kinase

Phosphocreatine kinase is a test for the activity of phosphocreatine kinase in the blood. Phosphocreatine kinase is mainly found in skeletal muscle and myocardium, and is also present in brain tissue. It is an enzyme involved in energy metabolism in the body. It is mainly used clinically to diagnose myocardial infarction. Laboratory Description: Creatine Phosphokinase (CPK), mainly found in skeletal muscle and myocardium, is also present in brain tissue and is an enzyme involved in energy metabolism in the body. It is mainly used clinically to diagnose myocardial infarction. In 2-4 hours after onset of myocardial infarction, the activity of this enzyme in the blood begins to rise. Basic Information Specialist classification: cardiovascular examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Generally should be normal. Normal value: Inorganic phosphorus method: 0-200U/dL Above normal: Common in progressive muscular dystrophy, polymyositis and muscle damage. negative: Positive: Tips: Do not smoke, drink alcohol, eat less high cholesterol food, take venous blood for 12 hours on an empty stomach. Normal value Inorganic phosphorus method 0-200U/dL. Colorimetry: men are between 0.55 and 7.5 U/dL and women are between 1.45 and 4.0 U/dL. Clinical significance Abnormal result 1. It has higher specificity than the aspartate aminotransferase and lactate dehydrogenase, but the duration is short, and it returns to normal after 2-4 days, which may be the phenomenon after myocardial infarction. 2, viral myocarditis, CPK can also be elevated, has a reference value for diagnosis and prognosis. 3. CPK can also be elevated during progressive muscular dystrophy, polymyositis, and muscle damage. 4, severe angina, pericarditis, atrial fibrillation, cerebrovascular accident, meningitis and heart surgery, etc., CPK can be seen elevated. People who need to be checked Middle-aged and elderly, heart disease and patients. High results may be diseases: congenital myotonia syndrome, angina pectoris, pericarditis, pediatric myocarditis, blunt closed heart injury Taboo before the test: Do not smoke, drink alcohol, eat less high cholesterol food, take venous blood for 12 hours on an empty stomach, do not exercise vigorously before taking blood. Inspection process Enzyme coupling method: Each laboratory can be programmed according to the automatic analyzer model and manual of this room. The main parameters are: 340nm wavelength, 37°C, sample to reagent volume ratio is 1:50, delay time 60s, reaction time 60s, power law. Not suitable for the crowd 1. Patients who have taken thyroid hormones, steroid hormones, etc., may affect the results of the examination and prohibit patients who have recently taken the drug history. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye.
