So how can we know if the liver is inflamed? If you pass the five tests of B-ultrasound and liver function, you can know whether the liver function is normal.

It seems that the test is complete, but the HBV DNA is a little high, but your liver is not inflamed. Hospitals are places where patients are concentrated and where experts are concentrated. Hepatitis B virus was found in patients with hepatitis, so it was concluded that hepatitis B virus caused hepatitis. There seems to be nothing wrong with the above logic, and people also like to listen to experts. Then, for example, it is easier for you to understand that the above logic is seriously problematic.

If there is a theft somewhere, the police will certainly investigate the scene. If "fingerprints" are found in the process of exploration, it will be of great help to solve the case. This is easy to understand. But if the above process is reversed, that is to say, there is no theft at all, but the police have nothing to do, just find a so-called "scene" and arrest all the owners of the fingerprints in the station for "hospitalization", then the problem will be big. Use this logic to analyze the above conclusion that hepatitis B virus causes hepatitis. Can you see the logical error?

Because the hospital is a place where patients are concentrated, that is to say, when people feel sick-when they feel uncomfortable, they will go to the hospital to seek the help of doctors. This is equivalent to a case. However, if a health examiner-who has no discomfort at all, just wants to ask a doctor to "tell fortune" for possible diseases in the future, it is equivalent to finding the "fingerprint" of hepatitis B virus when the doctor detects that the DNA of hepatitis B virus is on the high side and two pairs of semi-surface antigens are positive. I don't need to say it in the future.

Hepatitis B virus will not directly damage the liver, but its own immune system. For example, if people catch a cold, they will have a stuffy nose and some will have a fever. This is the immune system removing pathogens and repairing damaged parts. But this does not mean that people will catch a cold as soon as they have pathogens in their nasal cavity. It can be said that because of continuous breathing, there are many germs in everyone's nasal cavity, so everyone is a carrier of germs, but it is wrong to say that everyone is a cold patient. Generally speaking, people tend to see a doctor only when they are sick and have a cold. But no one who is uncomfortable will go to the hospital and ask the doctor to test how high the DNA of the pathogen in the nose is. It is a very interesting question what the doctor will say about a pathogen with very high DNA content in nasal mucus, but the doctor does not have a cold. Lenovo's current doctor-patient relationship, but there are many such topics.

Because doctors are not omniscient "God" experts, at present, "fortune telling" about what diseases they will get in the future can only be regarded as science fiction. At present, in view of the abnormal test results, the above problems will occur. Therefore, we can't ignore the examiner's own symptoms, but only rely on laboratory tests and test results to diagnose "diseases". Judging from your examination results, you are only a hepatitis B virus carrier, a healthy person, and have no uncomfortable performance.
