Even if the lipid test sheet is made by a large tertiary hospital, sometimes it will be inaccurate, and some are even "wrong" and have errors! Everyone may not have thought of this, right? Today Dr. Zhang will come to tell you that there is a kind of test list that is particularly easy to deceive everyone, and even doctors have been deceived. Let me take a look at the following test sheet:
A deceptive test sheet
Let's look at the two key lipid test indicators in this test list, one is triglycerides, the specific value is 9.28mmol/l, and the other is low-density lipoprotein cholesterol, the specific value is 1.34mmol/l. Many people may say, "Oh, triglycerides are really high, but LDL is very low." This is a good and a bad thing. ”
In fact, to tell everyone, this blood lipid test result may be a "wrong" and an illusion. This patient has high triglycerides, which is no problem, and the test is accurate. However, LDL cholesterol is low, which may be fake and not real. So, why is that? This also starts from the two types of methods for measuring blood lipids in Chinese laboratories at this stage.
At this stage, there are two methods for blood lipid testing in major hospitals in China. In layman's terms, it can be divided into two categories: specific measurement methods and formula calculation methods. The first method is that every indicator is measured, which is easy to understand, that is, every blood lipid index is tested in the laboratory, which is the same as everyone thinks. The formula calculation method measures one part of the blood lipid test and then uses the formula to calculate the other part. For example, the triglyceride is measured first, and the LDL cholesterol is calculated according to the formula according to the specific value of the triglyceride.
These two methods have one to calculate, both have certain defects, such as the above mentioned situation, when the triglycerides are significantly elevated, LDL, whether measured, or calculated, will be distorted, can not reflect the real situation. To be more specific, the triglycerides are too high, and the value of LDL is likely to be relatively low after being measured. And this low is not real, it is an illusion. Why is this happening? Let's give you an analogy, if you compare the human body to a container, then triglycerides are large balls, and low-density lipoproteins are small balls. When there are many large balls, whether it is measurement or calculation, it is difficult to make the small ball clear. Simple understanding, this is the truth. So, how should this situation be faced?
There are many big balls, and small balls are not easy to find
In reality, clinically, in the face of this situation, it is generally necessary to effectively treat elevated triglycerides under the guidance of professional doctors, and first lower abnormally elevated triglycerides as soon as possible. After the triglycerides are lowered, the blood lipids are reviewed, and the reduced triglycerides can no longer interfere too much with LDL, and the real situation of LDL can be clearly seen. In the face of whether the real LDL needs further treatment, it needs to be analyzed under the guidance of a professional doctor.
