How to detect anemia through blood test

Anemia has a huge impact on people's bodies. It is a disease caused by severe malnutrition, which brings great pressure to people's lives, because the onset of anemia will cause patients to lose physical strength, frequently experience symptoms such as dizziness, disrupt people's original rhythm of life, etc. Although anemia is very harmful, people do not pay enough attention to it, resulting in delayed treatment of the disease, etc. Let’s take a look at how to diagnose anemia through blood tests.

First, look at the HGB value: Most people have no problem analyzing the results of a routine blood test. 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 110 g/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.
