What does a complete blood test include

A complete blood test is what people often call a routine blood test. It is a particularly common examination method in clinical medicine. Because blood, as an important fluid in the human body, is often closely related to human health, when diagnosing a disease, a routine blood test is generally performed on the patient. So, what items are generally included in a routine blood test? The following will introduce you to the relevant knowledge in detail!

1. Definition of blood routine 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.

2. What does a routine blood test check?

A routine blood test examines the cellular part of the blood, mainly the number of red blood cells, white blood cells, hemoglobin and platelets. By observing these cells, it is possible to determine whether there are abnormalities, such as infection, anemia, blood system diseases, and the hematopoietic function of the bone marrow. If a pregnant woman suffers from severe anemia, there is a high probability that she will suffer from insufficient iron supply during pregnancy, which will affect the development of the fetus and be detrimental to her postpartum recovery. Therefore, it is important to conduct regular blood tests during pregnancy so that early diagnosis can be made, problems can be discovered in time, and treatment can be provided in time.

3. How to check blood routine

A routine blood test involves collecting blood from the finger or earlobe using a needle, diluting it and dropping it onto a special calculation plate. The plate is then placed under a microscope to count the number of blood cells, and the disease is diagnosed by observing the number and morphological distribution of these cells. How to check blood routine? A routine blood test is relatively simple and the results are usually available in about two hours.

1. Routine blood test items

Routine blood test items include red blood cells (RBC), white blood cells (WBC), hemoglobin (HGB), platelet count (PLT), neutrophil ratio (NEUT), lymphocyte percentage (LY), etc.

2. Precautions for routine blood test

(1) Is there any fasting requirement?

It is very important to have regular blood tests during pregnancy and pregnant mothers should take it seriously. Routine blood tests can be done at any time during pregnancy. It is recommended to fast during the first blood test because it will be accompanied by liver function tests. There is no fasting requirement for subsequent routine blood tests. Only the tests of blood biochemical indicators such as liver function and blood lipids require fasting. You can drink water during the routine blood test.

(2) Note after blood drawing

After the blood is drawn, pregnant women should press the wound with a sterile dry cotton ball (swab) for about 5 minutes. Do not bend your elbow to stop the bleeding, and do not twist the cotton ball to avoid subcutaneous bruising. The judgment standard is when the wound stops bleeding.
