Chapter 2918: 【2918】Exclusion method
Whether it is a disease or not, it is not the doctor who has the final say, but the medical evidence. A doctor's diagnosis is based on medical evidence. For this reason, every time the doctor sees this statement and expression of the patient, the doctor smiles bitterly.
It cannot be said that the doctor did not understand the patient's desire to cut the relationship with the disease early. Cao Yong discussed with the patient and said, "We need a blood test, head CT and MRI examination, and then further diagnosis."
"I've done the blood test. Doctor Xie said I went for the test, and the blood sugar is normal." The young man took out the same blood sugar test report as the previous aunt and handed it to the doctor for review.
The measured values are normal or abnormal, and ordinary people with a little culture can basically understand a little by themselves, because the inspection report is for the convenience of clinicians' reference, except that the normal value is printed next to the measured value. If the value is abnormal, the abnormality is directly marked on the inspection report.
What I want to emphasize here is that the understanding of ordinary people is not the same as that of doctors. The common people understand it based on the normal value as a reference. The blood test report is the same as the imaging report, and it is indicated that the clinician needs to make a comprehensive judgment based on the clinical symptoms of the patient.
is equivalent to saying that the normal value does not mean that the patient is definitely not sick, and the abnormal value does not mean that the patient is definitely sick.
After all, the changes of various components in human blood fluctuate greatly, and the measured values often only reflect the physical condition of the patient in a short period of time. This is the reason why doctors in the inpatient department often ask patients to draw blood for testing at every turn.
In the case of glucose tolerance test, you will find that whether it is an outpatient or inpatient department, the doctor will ask some patients to do more than one blood sugar test, and the time point of the two tests may be arranged every few days or weeks. At this point in the doctor's mind are some potential factors that may affect the test results.
fully shows that the doctor's thinking about a test result is multi-level and multi-faceted.
The young man who took out this blood sugar report thought he had ironclad evidence that he was not sick.
In the eyes of doctors, this is not a mountain of iron evidence that there is no disease, but it may be a mountain of iron evidence of other diseases. The clinical judgment of a disease requires an exclusion method. Your normal blood sugar paper is expected to become an exclusion method.
"The blood test I ordered again was not to check blood sugar, but to check other items."
"Is your blood sugar normal?"
"Your symptoms are not necessarily related to blood sugar."
The last sentence is the direction of the doctor's diagnosis.
The young man looked even more anxious when he heard this, and then stretched out his left hand to show the doctor: "It's not shaking anymore."
Several doctors looked over. The young man's left hand and left foot will not tremble again by himself. No more shaking. It won't be like this. The patient himself knows this best, how can he come to see a doctor if he is no longer shaking, how can he come and hang up the number of Dr. Xie persistently.
The young man slapped himself in the face, got angry with himself, grabbed the shaking left hand with his right hand, and tried to force his left hand to stop shaking.
Wei Shangquan, who was present, was the most anxious. He shouted to stop the patient and said:
"Hey, what are you doing with your hand? Don't grab it hard. If you grab it wrongly, it will break your bones."
The patient was taken aback by his words: "Can this break a bone?"
