Automatic biochemical analyzer is a test instrument often used in clinical practice. It can detect liver function, kidney function, myocardial enzyme spectrum, blood glucose, blood lipids, etc. and the household blood glucose meter is also an instrument to detect blood glucose. Some people often find that the blood glucose detected at home is different from that detected in the hospital. So, what is the difference between the household blood glucose meter and the hospital biochemical meter, and which detection method is more accurate?
As you can see, the blood glucose measurement in the hospital is usually done by taking venous blood for detection, and is automatically completed by using the full-automatic biochemical analyzer. Whether it is from the collection of blood samples or all links of the detection process, it is very little affected by human factors, so the accuracy is high. However, the diagnosis of diabetes can only be based on the results of the detection after the venous blood collection in the hospital. Although the results of blood glucose detection by the full-automatic biochemical analyzer are very accurate, the operation process is cumbersome, time-consuming, difficult to learn and master, and the price is too expensive. Generally, hospitals use it for batch detection.
The household blood glucose meter collects fingertip blood, that is, capillary whole blood. It has the advantages of small size, easy to carry, simple operation, less blood demand and easy to master. It can also be used by non-medical personnel. Due to the large number of operation details, it is greatly affected by human factors, which is easy to produce errors. Therefore, this method is only suitable for daily blood glucose monitoring, but not for the diagnosis of diabetes.
You may find that there is a certain gap between the test results of the home blood glucose meter and those of the hospital biochemical analyzer. This is a normal phenomenon. Don't worry too much, because the blood glucose of the body is affected by many factors, and the blood glucose values measured at different times are not comparable. As long as you pay attention to some problems that affect the test results, and use a qualified home blood glucose meter to measure the results according to the standard operation methods, Generally, the difference from the results detected by the automatic biochemical analyzer in the hospital will not exceed 0.5-1mmol / L.
The above is the difference between blood glucose meter and automatic biochemical meter, and which result is more accurate is introduced. Therefore, POCT blood glucose meter is often used to monitor daily blood glucose in the home of diabetes patients. In order to judge and analyze the condition of diabetes patients more accurately, the hospital will choose automatic biochemical analyzer for detection, so as to obtain more accurate detection results, especially when measuring low blood glucose value, it is more accurate to use automatic biochemical analyzer.
