Patients with liver injury need to undergo blood tests to check liver function, hemoglobin, coagulation function, and abdominal ultrasound or abdominal plain film. 1. For patients with liver injury, liver function tests will show elevated aminotransferases and bilirubin, and decreased albumin. 2. For patients with liver injury, check the blood routine to see if the hemoglobin decreases. If the liver injury is caused by trauma and rupture of liver, the hemoglobin will decrease. 3. If the liver injury is caused by trauma, it is necessary to check the abdominal ultrasound or abdominal plain film to see whether there is free gas under the diaphragm and whether the diaphragm is elevated, and if necessary, carry out abdominal puncture examination to confirm whether there is liver trauma. Liver injury patients need to go to the hospital in time, do not be careless, so as not to delay treatment.
