The cause of high white blood cells and high alanine aminotransferase may be viral infection. There are more etiologic factors that cause high white blood cells and high alanine aminotransferase, such as acute viral hepatitis, chronic hepatitis, active cirrhosis, hepatocellular carcinoma, and heart failure. Albuminous aminotransferase (ALT) is mainly found in various cells. In the acute stage of viral hepatitis and toxic hepatocellular necrosis, ALT is released into the blood. The amount of aminotransferase in the liver is about 100 times higher than the amount in the blood.ALT is an important indicator for the diagnosis of viral hepatitis and toxic hepatitis. Elevated white blood cells are seen in various cellular infections, inflammation, and severe burns. When both are elevated at the same time, it may indicate a viral infection. If there is any abnormality in the above biochemical indexes, it is necessary to consult a doctor as soon as possible and clarify the cause of the disease under the guidance of a professional physician to avoid delaying the condition.
