Routine blood examination is a routine item that must be carried out by patients to outpatient, emergency or hospitalization, which is the most common, the most common, the most basic, and also the most cost-effective examination item. It is a precise exploration of the movement of blood in the body.
Blood is the body's "delivery man".All the organs and tissues of our body do not have the ability to "bury the pot and cook" and "start their own business", and they have to rely on blood to send oxygen and nutrients, and without blood, we will starve.
Blood is the "guardian" of the body, blood flows through the whole body, there are "highways" (arterial veins), "provincial and county roads" (small blood vessels), "sheep intestine paths" (capillaries), blood vessels are blocked, cracked, you can detect and prompt.
Blood is the body's "caregiver".After the patient eats the drug, it is metabolically synthesized and absorbed into the blood, and the blood will carry the drug components to the lesion.
Blood is the "informant" of the bodyIn the process of sending nutrients and oxygen to the blood, the east enters and the west goes out, and there are problems and abnormalities, which can be understood quickly, and the abnormal values will be reflected in the blood routine.
Blood is still the "model worker" of the body, which is always flowing and does not stop, so its reflection in the blood routine is more intuitive.
Blood is mainly composed of 3 types of cells with different functions:
One is the "red blood cells", which act as a transport team and mainly carry oxygen.
One is "platelets", which act as a maintenance team and mainly play a role in hemostasis.
One is the "white blood cell", which acts as a security guard and mainly plays an immune role.
These three major cell teams, each with their own team below, are summarized together to form a blood routine report, and the data in it are mainly classified into three categories:One is counting, proportionality; One is the volume, average volume; One is the distribution width。They all have normal reference values, high or low will indicate different pathologies, some light and some severe, some large and some small, some strong and some weak.
According to these numerical changes, doctors can quickly determine the possible direction and type of disease, and if they are inaccurate or the disease is severe, further pathological examinations, imaging examinations and other items are required, which is the significance of blood routine examination.
If there are 3 abnormalities on the blood routine report, the doctor does not want to see it, and the patient should be prepared for the worst.
1. Hemoglobin in red blood cells, expressed as a numerical value, and a lower than normal value means anemia,If it is less than 90 g l, indicating a significant decrease in the ability to transport oxygen, which is highly valued by doctors.
If this value is abnormal, the patient will frequently experience palpitations, palpitations, irregular heartbeats, and even cardiac arrest. In severe anemia, the likelihood of sudden death is greatly increased.
2. The normal range of platelets is also expressed as a numerical valueIf the value is too high or too low, it indicates abnormal coagulation functionIf it is less than 80 10 9 l, indicating that the hemostatic effect is basically lost, and the doctor will be nervous.
The patient's organs and tissues will spontaneously appear internal bleeding, without warning, anytime and anywhere, common such as **ecchymosis, nasal bleeding, gum bleeding, if important internal organs bleed, the body will be reflected through the size of the stool, once intracranial hemorrhage, it will bring life-threatening.
3. Slight fluctuation of white blood cells indicates inflammation, if the value is too high, it reaches 18 10 9 L, indicating that the human immune system is nervous, excessive stress response, serious infections will occur, indicating leukemia, uremia, poisoning and other problems, and if not timely intervention will be life-threatening.
Therefore, the decrease in hemoglobin, the decrease in platelets, and the increase in white blood cells respectively reach the "danger line", which is a proper serious disease, and the doctor will immediately arrange observation for further examination and treatment.
