Albumin transaminase 90 U/L and albumin transaminase 50 U/L are not normal. The current normal values for both serum alanine aminotransferase and aliquot aminotransferase are 0 to 40 U/L. alanine aminotransferase 90 U/L and aliquot aminotransferase 50 U/L are not normal. This is the most commonly used broad serologic indicator of clinical response to liver function. The severity and possible causes of the condition are considered based on the ratio of alanine aminotransferase, glutamine aminotransferase, and glutamine aminotransferase/glutamine aminotransferase. Mild elevations of alanine aminotransferase and glutamine aminotransferase, with predominantly elevated glutamine aminotransferase, 50/90 < 1, are considered to be highly probable for acute hepatitis or chronic hepatitis in its mild form. If alanine aminotransferase, glutamic oxal transaminase test is abnormal, you need to consult a doctor in a timely manner to clarify the cause and then standardize the treatment, and remember not to blindly use drugs on your own, so as not to cause adverse effects on the body.
