HEALTH REGULAR is one of the most common and basic laboratory tests in clinical practice. Generally, when we go to the hospital for examination, the doctor will first say "Go to test for blood."

Why do you have to check blood routines as soon as you go to the hospital?
blood routine examination items can be as many as 20, including erythrocyte count , hemoglobin concentration , leukocyte classification count and platelet , etc. In fact, it is generally divided into three major systems, leukocyte system, erythrocyte system and platelet system.
Usually when we get the inspection report, there are usually two columns. One is the examination result and the other is the reference value . The doctor will judge which problem occurs in our body based on the reference value and the examination result. The normal value has not changed at all. If exceeds the upper limit of the normal value or is lower than the lower limit of the normal value, some arrows of ↑ and ↓ will appear.
Through blood routine examination , hematological system diseases, infectious diseases, coagulation function diseases, etc. can be seen separately. The coverage is relatively wide. Blood routine examination can be used as the basic judgment of the examination. Of course, wants to interpret the values of blood routines, and the results must be combined with the patient's medical history and symptoms and comprehensive evaluation.

Can cancer be detected?
The prevalence of cancer has been increasing in recent years. For a family, if a person suffers from cancer, it will drag down the entire family, so everyone will feel particularly scary about cancer. However, experts have repeatedly proposed that cancer prevention is greater than treatment, so it is very important to do a check-up in advance and kill cancer in the cradle in advance.
Nowadays, many people have developed the good habit of having a yearly physical examination. So, can ordinary physical examinations be performed on a malignant disease such as cancer, such as routine blood tests to detect the existence of cancer?
Hydrome Department of Laboratory Department of the First Affiliated Hospital of China University of Science and Technology Deputy Chief technician Li Ming said that generally cannot detect solid tumors through routine blood tests.
blood routine does not belong to the screening indicator for cancer. It mainly checks the number of blood cells . If you want to confirm whether there is cancer in the body, you should also combine other tests to comprehensively judge, such as nuclear magnetic resonance, x-ray examination, CT examination , tumor marker examination, etc.
Take leukemia , such as blood cancer, through routine blood tests, most patients' leukemia will indicate an increase in leukocyte , and the late stage of the disease will increase significantly, , but there are also a few patients with leukocyte count is within the normal level or decrease in .
Hymal routine can only play an auxiliary role in the diagnosis of leukocytes. It is unrealistic to diagnose leukemia by single blood routine . In the end, it is necessary to pass routine bone examinations and bone marrow aspiration , etc.
For other cancers, routine blood tests can be used as an important reference standard for the diagnosis of gastric cancer, but cannot clearly diagnose gastric cancer . Even so, many doctors will still ask us to do a routine blood test first.
Because blood routine examinations are the basic examinations, they can prompt many diseases, but they only prompt the direction of the disease. If you want to clearly determine which disease, , especially cancer, needs to combine other more examinations.

If there are 3 situations in the results, it is recommended to further review
lymphocytes increased
lymphocytes account for 36% of the total blood components of the human body. relies on endogenous secretion and exogenous supplementation for separation and integration. The abnormalities of lymphocytes can be divided into two types. is physiological and the other is pathological.
If inflammation occurs in the body due to certain factors, the number of lymphocytes will increase compared with normal conditions. In this case, inflammation can be relieved by taking anti-inflammatory drugs. The number of lymphocytes in
should not be too small. If there is too little , you should be alert to the risks of leukemia and other diseases, and further examination is needed.
hemoglobin index increases
The most important function of hemoglobin is to realize blood transport, and on this basis, the low-fat protein toxins in the blood are excreted from the body, so as to achieve the occurrence of anemia symptoms and metabolic inflammation.
If you find that hemoglobin is elevated, you must pay attention to the possibility of a thrombosis or cerebral infarction , and further examination is required.
The number of white blood cells increased
If you find that the number of white blood cells in the body has increased when doing blood routine, then you need to analyze it from multiple aspects. There are many factors that cause the increase of white blood cells. It may be because of inflammation in the body, or it may be because of blood system diseases. Viral infections and bacterial infections will also lead to an increase in the number of white blood cells.
No matter what the situation causes the increase in the number of white blood cells, everyone needs to do further examinations and targeted treatment.
