Since the blood test is no good, I will tell you directly if I suspect that I have an infectious disease. I estimate that the transaminase (ALT) should exceed the normal value.
This value mainly reflects the degree of liver cell damage. If you don't have a good rest, or your diet contains some irritating substances, it may cause an increase. Therefore, if ALT rises, you may wish to have a mild and light diet. You must not eat in the morning, pay attention to rest, and don't do strenuous exercise and overwork. If you continue to rise like this, you should be alert to whether you have liver disease.
