What are the precautions for blood routine tests

Countless people have had routine blood tests in their lives. In fact, the physical examination we did at the hospital before starting work included a routine blood test. However, many times due to our good health, we did not pay much attention to the results of this test. If we look carefully at the test report of the routine blood test, we find that the four most basic test results are total white blood cell count, platelets, total red blood cell count and hemoglobin.

Routine blood tests are not only the main basis for diagnosing various blood diseases, but also can provide a lot of important information for the diagnosis and differentiation of other systemic diseases. It is one of the most commonly used and important basic contents in clinical medical tests. The most primitive means of routine blood test is manual microscopic examination through a microscope. With the development of basic medicine and the application of high science and technology, blood cell analyzers have become an important means of replacing microscopic examination for routine blood analysis, especially blood analyzers with classification.

Laboratory tests must fully consider the various factors that affect routine blood tests and strictly control them: in order to obtain accurate and reliable test results, high-quality specimens must be obtained. High-quality specimens are the first step to high-quality testing. Ensuring the complete morphology of each cell in the blood specimen is the most basic requirement for high-quality specimens used for routine blood tests. Blood is a red viscous suspension composed of two parts: blood cells and plasma. When performing blood cell counts, it is difficult to count blood directly. Whether it is microscopic examination or using a blood cell analyzer, the blood must be appropriately and accurately diluted before the blood cell count can be performed.

Here are some things to note about routine blood tests. I would like to remind you again here that you must pay attention to the results of routine blood tests. Often, many diseases can be detected through routine blood tests, and can even be clearly diagnosed. For example, some people suffer from thrombocytopenia, or have a purulent infection in the body. At this time, a routine blood test is of great diagnostic significance.
