With the increasing awareness of health care, most people have the habit of going to the hospital for a physical examination every year, which can help detect problems in time. However, many people do not know the purpose and items of some routine examination items. Blood routine examination is a common examination item that is required for routine physical examination or pre-employment physical examination. So what items are included in the blood routine examination? I believe everyone will be curious about this question. Let's take a look at the detailed introduction below.

1. White Blood Cell Examination

An increase in neutrophils is mainly seen in cases of suppurative bacterial infections in the body; a decrease is seen due to the use of certain drugs, certain diseases such as influenza, radiation exposure, rheumatic diseases, certain blood diseases, and other reasons. Lymphocyte increase is seen in infections caused by certain viruses such as measles, viral hepatitis, tuberculosis, and lymphocyte proliferative diseases. A decrease is mainly seen in cases of exposure to radiation and the use of adrenocortical hormones such as prednisone.

2. Red Blood Cell Count Examination

Anemia or blood loss can affect the number of red blood cells. High values may indicate polycythemia, while low values may indicate anemia.

3. Hemoglobin Examination

Hemoglobin is present in red blood cells and is a substance that transports oxygen to provide the necessary oxygen for the body. Due to menstrual and pregnancy effects, hemoglobin levels in women are generally lower than in men, making women more prone to anemia. High values may indicate polycythemia or decreased cardiac output, while low values may indicate hypochromic anemia or iron-deficiency anemia. Generally, hemoglobin levels below 10g/dl in both men and women indicate severe anemia, and a decrease of 1-2g/dl from the normal value is generally not a major concern.

Blood routine examination is indeed a simple and effective examination method. The above has provided specific answers to the specific examination items and the concept explanation of routine indicators in blood routine examination. When undergoing blood routine examination, please pay attention to the above-mentioned points.
