Maybe many people have the experience of going to the hospital. After arriving at the hospital, the doctor takes a cursory look at the symptoms and consults about the disease, and then writes a bunch of lists for the patient to go for tests.
If you are going to be admitted to the hospital for treatment, blood draws, ECGs, CTs, all of these are essential items, and you can't run away from them. Many people may think that this is not reasonable.
In the past, some doctors might see a patient with just three fingers and press a button to reach a conclusion. But nowadays, doctors have to go through a series of diagnostics before coming to a conclusion.
When you ask a doctor a question during your first visit, he or she may not even answer it positively, and will just tell you: wait until after the examination.
We think the doctor is putting it off, but it's not. Because nowadays the medical level is much higher than before, and there are more advanced medical equipments. Through the diagnosis of these medical equipments, we can have a more accurate answer to the patient's condition.
If you are still following the old ways, you can just diagnose and prescribe medicines. Then there is a high risk of misdiagnosis, and the possibility that some major problems may not be diagnosed.
Some people's illnesses are already very serious, and if they don't have these tests done in time, there may be no way to undo them. Like some cancers are actually a nodule or a small tumor in the early stages, which can still be treated in time.
But if the doctor is just, just relying on his own experience, then these conditions may not be detected.
So a blood draw, an EKG, a ct, these are just basic tests, but they can rule out a lot of problems, they can help the doctor rule out a lot of possibilities. It's like an annual physical, done just in case.
But if you don't do it, it's too late to regret it when there's a real problem.
