How to check if there is anemia in blood test?

In fact, there are quite a lot of people suffering from anemia in our lives, especially women, because they have menstruation for a few days every month, so they are particularly prone to anemia. The symptoms of anemia may not be obvious at the beginning, but when it reaches a certain degree, the patient will have symptoms such as pale complexion and general fatigue. If it is not examined and treated in time, once severe anemia occurs, it may bring serious adverse consequences. Therefore, when abnormalities are found, a routine blood test should be performed in time to confirm whether anemia has occurred. So, how does a routine blood test determine whether there is anemia? Next, the expert will introduce it to us.

Several arrows often appear in the blood routine report, such as hemoglobin concentration of 125 (reference value: 110-150), mean corpuscular hemoglobin concentration of 310g/L (reference value: 320-360), and mean platelet volume of 13.9fl (reference value: 7.0-11.0). In addition to the items mentioned above, there are also the coefficient of variation of red blood cell distribution width, mean corpuscular volume, etc. So how can we use the blood test report to determine whether we have anemia or what disease we have?

How to analyze the results of routine blood tests to determine whether there is anemia?

First look at the HGB value: Most people have no problem analyzing the results of routine blood tests. The main thing is to see whether anemia exists, and the hemoglobin concentration (HGB) value is the main data for determining whether anemia exists. The normal reference values ​​of hemoglobin for various populations are as follows: normal adult women: 110-150g/L, men: 120-160g/L, newborns: 170-200g/L, children: 110-160g/L. Generally, an adult with hemoglobin <110g/L is considered anemic. Clinically, a level below 110g/L is considered mild anemia. A level below 90 g/L is moderate anemia, and a level below 70 g/L is severe anemia.

How to determine whether you have anemia: If the hemoglobin concentration (HGB) is lower than 110g/L at the same time, it can basically be determined as iron deficiency anemia. Iron deficiency anemia is what we usually call anemia. It is most common in women, pregnant women, children, and the elderly. You don't need to worry too much about iron deficiency anemia. Generally, by taking iron supplements such as Iron Edge tablets, hemoglobin will increase significantly after one month, and hemoglobin concentration will return to normal after two months, and anemia can be improved and corrected. Another data that can be used as a reference to see if you have anemia is the total red blood cell count (RBC). The main function of red blood cells is to transport oxygen. If the number of red blood cells in the blood is measured to be lower than normal, it may mean anemia.

The third is to look at the total number of platelets. The main function of platelets is to stop bleeding. Thrombocytopenia leads to poor coagulation function. Patients are prone to bleeding or bleeding is difficult to stop. It can manifest as skin, mucous membrane bleeding, nose bleeding, gum bleeding, etc. In severe cases, hemoptysis, hematemesis, and even cerebral hemorrhage may occur. Many systemic diseases, tumors, blood diseases, etc. can cause thrombocytopenia.

Fourth, look at the total white blood cell count, which includes lymphocytes and neutrophils. The increase or decrease in the total white blood cell count is mainly affected by the number of neutrophils, and changes in the number of lymphocytes can also cause changes in the total white blood cell count. Infectious diseases (such as colds and fever) often cause changes in the number and classification of white blood cells. The main function of neutrophils is to phagocytize and digest various microorganisms that invade the human body, such as bacteria, and various necrotic cells in the body. It is one of the most important functions in the blood's nonspecific defense system. An increase in neutrophils is mainly seen in various purulent bacterial infections in certain parts of the body. Lymphocytosis is seen in certain viral infections such as measles, viral hepatitis, etc.

In addition to the above-mentioned main reference items for analysis of routine blood test results, there are many auxiliary reference items, such as platelet volume, mean corpuscular hemoglobin concentration, eosinophil count, etc. These items can help to specifically determine the cause of the disease, but if only one or two tests are abnormal, it does not mean anything.
