Why do you have to draw blood as soon as you get to the hospital? Doctor: where did the blood finally go?

“Doctor, the serum carcinoembryonic antigen is higher than normal. Am I suffering from cancer?” Xiao Liang looked at the results of his physical examination report and was surprised.

blood routine is the most common indicator in physical examination. Basically, as long as you come to the hospital, the doctor will let you draw a few tubes of blood, which can check blood glucose, blood lipid, anemia, etc. in recent years, blood routine has added a lot of examination of tumor markers. Many people are curious. Can such a simple blood routine find traces of cancer?

Hb is a very important component of red blood cells and a protein that can participate in oxygen transport. This index can help the examinees to preliminarily judge whether they have anemia and whether their hematopoietic function is abnormal. HB “↑” means that there may be respiratory problems such as hypoxia, dehydration, chronic obstructive pulmonary disease, etc.; and “↓” means that there may be various types of anemia, blood loss and other problems such as iron deficiency anemia.

the most important function of platelets is coagulation and hemostasis, so this index is of great significance for us to judge whether the coagulation function mechanism of the subject is normal, and the reference index is × 109 / L.

value “↑”, the range is [× 109 / l], which is slightly increased, mostly related to infection, iron deficiency anemia, etc.; if the value is greater than 500 × 109 / L, it is obviously increased, and attention should be paid to myeloproliferative diseases such as thrombocytosis; if the value is “↓”, be careful of infection, immune thrombocytopenic purpura, leukemia, etc.

the white blood cells in the test sheet we see refer to the total number of white blood cells in the blood. We need to pay attention to the percentage changes of various types of white blood cells.

when the WBC value rises between × 109 / L, we should be alert to bacterial infections such as pneumonia and urinary infection; when the value exceeds 30.0 × 109 / L, be careful of blood diseases; when the value exceeds 50.0 × 109 / L, it is likely to be malignant hematogenous leukemia. If the WBC value decreases, we should be alert to liver disease, virus infection and autoimmune diseases.

this type of anemia is the most common, especially in pregnant women, because during pregnancy, a large amount of iron needs to be supplemented. Once lacking, it is easy to cause iron deficiency anemia. After illness, can appear fatigue, pale face, dizziness, easy fatigue and other performance, at this time do a blood routine examination, you can very good discovery of the disease.

the disease has two peaks. After 20 years old and 60 years old, the patients often appear anemia, bleeding and infection. However, because these manifestations can be caused by respiratory tract infection and malnutrition, it is difficult to pay attention to it. It is suggested that if there are symptoms such as pale face, abnormal fatigue and fatigue, subcutaneous tissue bleeding, oral mucosa or gingival bleeding, etc When, can check blood routine, to discover this disease to have a lot of help.

thalassemia is a hereditary blood disease. If MCV and MCH show MCV ≤ 82fl and MCH ≤ 27.0pg during blood routine examination of pregnant women, it indicates that there is abnormality, and it is necessary to pay attention to thalassemia or thalassemia gene carriers. At this time, if the husband also detected thalassemia, the probability of inheritance to the child is great. Therefore, it is recommended to know whether you are a thalassemia gene carrier before pregnancy. If yes, do a good job in screening and diagnosis, it can effectively

occur in children aged 2-7 years. It is suggested that if there are fever, anemia, bleeding, bone and joint pain, hepatosplenic lymph node enlargement and other symptoms of unknown cause, make a blood routine diagnosis as soon as possible.

the main cause of leukemia is decoration pollution formaldehyde. The newly decorated house or newly bought furniture must be ventilated for a period of time before reuse.

Studies in the UK have shown that thrombocytosis can predict the role of potential malignant tumors in clinical practice. If thrombocytosis is regularly investigated, a considerable proportion of lung cancer and colorectal cancer can be diagnosed at least two months in advance.

if cancer is suspected, blood samples will be drawn to check tumor markers, that is, three tumor tests. The results of these three markers have important implications for cancer. But it is only a warning function. If you want to make a definite diagnosis, you have to cooperate with pathological examination.

a tube of blood will be drawn for different tests. Because some tests need to add special substances to the tube to get the results, several tubes of blood should be drawn every time we go to the inspection.

in fact, we only need to use a little bit each time. Is the remaining blood thrown away? The blood drawn out will be sent to the laboratory first. The doctor will analyze the blood and get the inspection report. If there is any blood left, it will be saved first. If the patient has objection to the test result, he can apply for reexamination, so that there is no need to draw blood again. After about a week, the blood will be disposed of as medical waste. Focus
