Low neutrophil count in blood test

If the neutrophil count in a routine blood test is low, the main reason is inflammation. If the neutrophil count in a routine blood test appears alone, it cannot be used as a basis for clinical diagnosis. This is because such a phenomenon may occur due to dietary reasons, poor rest, etc., which may also lead to abnormal test results. Therefore, when looking at a routine blood test, you must look at it comprehensively and in combination with the manifestations of some diseases.

Definition of routine blood test Routine blood test is one of the most basic clinical laboratory tests. The test items include the number of red blood cells, white blood cells, hemoglobin and platelets. Blood is collected from the finger or earlobe by acupuncture, diluted and dripped onto a special calculation plate, which is then placed under a microscope to count the number of blood cells. Diseases are diagnosed by observing the number and morphological distribution of these cells. This is the definition of a blood test. Routine blood test is one of the commonly used auxiliary means for doctors to diagnose diseases.

The commonly used symbols on the routine blood test report are: RBC stands for red blood cells, WBC stands for white blood cells, HGB stands for hemoglobin (hemoglobin), and PLT stands for platelets.

How to read the results of blood routine test

1. How to analyze the results of routine blood tests

The blood routine test report includes red blood cells (RBC), hemoglobin (Hb), white blood cells (WBC) and white blood cell differential count, hematocrit (HCT) and platelets (PL), etc. There will be normal reference values ​​on the right side of the report. When the test results exceed the reference values, in addition to being able to see it from the numbers, there will also be symbols "↑" and "↓" to indicate that it is higher or lower than the normal reference value. When looking at a routine blood test report, the data on white blood cells, red blood cells and platelets are the most critical.

2. Hemoglobin and red blood cells

The main function of hemoglobin is to carry oxygen molecules, and it is the most numerous type of blood cell in the blood. The normal concentration range of hemoglobin is 110~150g/L. If the hemoglobin concentration of an expectant mother is greater than 150g/L, there may be a lack of oxygen in the blood. If hemoglobin and red blood cells decrease at the same time, acute or chronic blood loss, lack of hematopoietic factors, hematopoietic disorders, hematopoietic tissue damage, anemia, etc. may occur.

The criteria for judging whether an expectant mother is anemic vary at home and abroad. In China, the normal value of hemoglobin is 100g/L. Below 100g/L is mild anemia, below 80g/L is moderate anemia, and below 60g/L is severe anemia. In foreign countries, the normal hemoglobin value is 110g/L, and below 110g/L is mild anemia. A level below 90 g/L is moderate anemia, and a level below 70 g/L is severe anemia.

3. White blood cells

The main function of white blood cells is to eliminate pathogens and protect health. During pregnancy, white blood cells have a certain room for increase. They begin to increase from the 7th week of pregnancy and reach the peak at the 30th week of pregnancy. Its normal value range is (5~12)×10^9/L, and the highest can reach (14~16)×10^9/L. If it is higher than the pregnancy range, it means that the expectant mother may have inflammatory infection, bleeding, poisoning, etc.

4. Platelets

The normal range of platelet values ​​is PLT (100~300)×109/L. If the platelet count is lower than 100×109/L, it will affect the coagulation function of the expectant mother.
