Not a big deal, this kind of test results in the first, second, fifth, seventh slightly high and surface antigen positive or not have no correlation. For various reasons, I wanted to do a statistical comparison of surface antigen positive and non-positive liver function abnormalities. But the conditions were not good enough to do it. But after a cursory perception, I feel that there should be no correlation. You know, simply put, there should be no difference in liver function abnormalities between surface antigen positive people and surface antigen negative people. However, for the abnormally elevated ghrelin, there is a classification of 50 to 100 units, 100 to 200 units, and more than 300 units. The number of patients was not large enough for a large sample to be counted. However, the small sample statistics can also explain some of the problems, to see that the number of people belonging to the first class is high, due to health checkups. The target population of the physical examination is no symptoms of disease. And it is not possible for a person to continuously monitor ghrelin on a laboratory machine with blood vessels connected to it for 365 days. The frequency of blood draws for health checkups can be said to be evenly distributed over 365 days. Furthermore, the results of a particular test are equivalent to taking a static picture of a dynamic process. Therefore, counting the data in a year is equivalent to superimposing the static photos. From the big data, it is possible to indirectly analyze the duration of the abnormal alanine aminotransferase level. In other words, the statistical model can indirectly conclude that high ALT can return to normal without treatment. The recovery time for a small sample is up to two weeks. It can be assumed that if it takes longer than two weeks to recover, uncomfortable symptoms of the disease may appear. And the symptoms will certainly no longer run to the health checkup hospital for health checkup, but will run to the big tertiary hospital for disease checkup. This is a hypothesis that needs to be further proved as to why there are more symptomatic patients with high ghrelin than those who have health checkups in the big tertiary hospitals. Of course, the verification of the hypothesis requires conditions, the first is certainly the reagents and machines to be stable, the repeatability of the glutamine transaminase must be good, at least should not be repeatable difference will reach 20%, right. Otherwise, the assay method for GGT is very problematic, and the assay method that is problematic cannot be used as a "golden index" for measuring liver function at all.
