cerebrospinal fluid alanine aminotransferase

Due to the influence of the blood-brain barrier, aminotransferases in cerebrospinal fluid and serum cannot communicate with each other, and diseases other than the central nervous system generally do not affect the aminotransferase of cerebrospinal fluid. Therefore, the determination of cerebrospinal fluid aminotransferase activity only reflects the lesions of the central nervous system. Central nervous system diseases are different from liver diseases, and AST has more diagnostic value than ALT. Basic Information Specialist classification: growth and development check classification: cerebrospinal fluid examination Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: normal. Normal value: Cerebrospinal fluid alanine aminotransferase: 0-20U Above normal: Increase brain metastases, cancerous neuralgia, cerebral or cerebellar degeneration, cerebral infarction, toxic encephalopathy, brain trauma, and nervous system inflammation. negative: Positive: Tips: Hepatotoxic drugs or drugs that cause biliary obstruction can cause an increase in enzyme activity. Normal value <20U. Clinical significance Increase brain metastases, cancerous neuralgia, cerebral or cerebellar degeneration, cerebral infarction, toxic encephalopathy, brain trauma, and nervous system inflammation. High results may be diseases: acute toxic encephalopathy in children, brain injury considerations Hepatotoxic drugs or drugs that cause biliary obstruction can cause an increase in enzyme activity. Inspection process Use the colorimetric method. Not suitable for the crowd 1. If there is obvious papilledema or cerebral palsy, contraindications are contraindicated. 2. Patients who are in shock, exhaustion or endangered state and local skin inflammation, and lesions in the posterior cranial fossa are contraindicated. Adverse reactions and risks If the patient has symptoms such as breathing, pulse, or abnormal color during puncture, stop the operation immediately and deal with it accordingly.
