The most common explanation is that the doctor is giving himself leeway, and he is not telling you clearly that there is nothing wrong with your body, and that you are in a state of absolute normality.
Doctors do not dare to make a promise, the reason is very simple, because some of the disease at the present stage there is no way to find out, must have to wait until a medical science and technology advances in the years 20 years after the discovery of the possibility, and the doctor is now directly to you characterized as normal, in the next period of time in the next time, once your condition suddenly appeared, or the condition of the sudden deterioration of the disease, it is very likely that the doctor will be looking for trouble.
But the crux of the matter is that doctors are old and young, and they don't dare to take on such a big risk and problem, and one way or another there is such a phrase, no abnormality found.
Not found abnormal often have a time limit, this time limit, that is, is in the current stage of the state and did not find abnormal, but there is no one this abnormal or that you are now not normal, who knows, who does not know, we just follow the process to do things.
In accordance with the process to do things after you sign a letter to you stamp on it, the doctor only need to be responsible for this, for other things there is no need to be overly responsible for, if a doctor once to see a patient, you need to do 100% all-around care and care of him, simply can not take care of it, and if it really presents this state, the price of medical care will show an exponential increase.
In addition to the most important point is a carrot, you go to the hospital to check what you go to the hospital to do what there will be a fixed process, in this fixed process, who can not go to the left, who can not go to the right, you must go in the middle of the line.
And then go to the center of this line must ensure that absolutely can not happen any change and change, once something happens that is the responsibility of the doctor. In other words, the doctor to fill in these words, may people do not realize why to fill in these words, just the hospital regulations down, just the higher leadership has been required, must fill in these words, rather than that go to fill in the normal.
Of course, to a certain extent, fill in no abnormalities, than fill in the normal to be much better, after all, the current stage of not found abnormalities, can only show that you in the existing medical equipment under the detection of a number of okay, but if the medical technology to the previous 20 years 20 years, in case of checking out the other diseases, then at this time you let the doctor responsible for that, that is obviously not reasonable.
The doctor filled in this way is justifiable, there is no need to be too harsh.
