Muscle atrophy cannot be detected by liver tests, but can be determined by physical examination, blood tests, electromyography and many other tests. 1. Physical examination: Observe whether the patient has obvious muscle atrophy, whether there is pain and swelling on palpation, whether there is skin abnormality on visual examination, and whether there is any abnormality in movement. 2. Blood test: blood test can be used to determine whether there are symptoms of malnutrition; thyroid hormone test to clarify whether there are endocrine diseases; muscle enzyme test to clarify whether there is muscle destruction. 3. Electromyography: Concentric needle electrodes record various electrical activities of muscles in quiet state and in different degrees of random contraction. If there are 3 abnormal liver tests, you need to go to the hospital under the guidance of the doctor, combined with other tests to clarify the cause of the disease and carry out targeted treatment.
