Dear Mr. Jiang, the test results of your blood donation changed from alanine to ammonia.

The normal reference value of alanine aminotransferase is 0 ~ 40u/L, and when it exceeds 40u/L, it is called alanine aminotransferase elevation.

As long as 1% hepatocytes are destroyed, serum enzymes can be doubled. Therefore, alanine aminotransferase is recommended by the World Health Organization as the most sensitive detection index of liver function damage.

If the serum alanine aminotransferase (ALT) level exceeds the normal upper limit by 2-3 times and lasts for more than two weeks, it suggests that there may be hepatobiliary diseases, but the damage to the liver caused by alcoholism and chemical drug poisoning should be excluded. Contact with chemicals, such as carbon tetrachloride, some heavy metals, arsenic, etc. Can cause toxic hepatitis) and under physiological conditions, such as overwork and strenuous activity (lactic acid is produced and accumulated in the body, which makes the body relatively hypoxic and hypoglycemia, leading to increased membrane permeability of hepatocytes and elevated transaminase), transaminase may temporarily increase during menstruation.

The elevation of alanine aminotransferase should be comprehensively judged according to relevant examination, medical history and symptoms and signs. When alanine aminotransferase in patients with hepatitis B rises to more than 2 times the upper limit of normal value, antiviral treatment should be carried out. The higher the level of transaminase, the more active the immune function of patients and the better the effect of antiviral treatment. This is the best time for antiviral treatment of hepatitis B.

I suggest you go to the hospital for examination and seek professional advice according to your examination results.
