CSF glutamine

The free ammonia produced by deamination in the amino acid metabolism of brain tissue can synthesize glutamine by the action of glutamine synthetase to eliminate the toxic effect of ammonia on the central nervous system. Ammonia in cerebrospinal fluid is about 1/3 of arterial blood. People who need to be tested: people with impaired liver function, difficulty breathing, chest pain, vomiting, and convulsions. Basic Information Specialist classification: examination classification: cerebrospinal fluid examination Applicable gender: whether it is fasting: Analysis results: Below normal: No relevant information. Normal value: Cerebrospinal fluid glutamine: 0.41-1.10mmol/L Above normal: When the glutamine in the cerebrospinal fluid rises, it can also reflect the increase of ammonia in the brain, and can be used to diagnose hepatic encephalopathy; it can be found in advanced cirrhosis and hepatic coma, up to 3.4mmol/L; hemorrhagic meningitis, septic encephalopathy and respiratory failure Mild increase in secondary encephalopathy. negative: Positive: Tips: Stop eating all the drugs that can affect the test results. Normal value 0.41 to 1.10 mmol/L. Clinical significance Abnormal result When the glutamine in the cerebrospinal fluid rises, it can also reflect the increase of ammonia in the brain and can be used to diagnose hepatic encephalopathy. Found in advanced cirrhosis, hepatic coma, up to 3.4mmol / L. Hemorrhagic meningitis, sepsis encephalopathy, and respiratory failure have a slight increase in secondary encephalopathy. People who need to be tested People with impaired liver function, difficulty breathing, chest pain, vomiting, and convulsions. High results may be diseases: hepatic encephalopathy, cirrhosis Before testing: Stop eating all the drugs that can affect the test results. At the time of testing: Subjects should follow the doctor's instructions. Inspection process Part of the cerebrospinal fluid was taken and the content of glutamine was detected chemically. 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.
