A blood test is an indispensable item during a physical examination, so what diseases can be detecte

Blood tests are an essential part of the physical examination, so blood tests can be done for routine bleeding or blood analysis. Determine if there is an infection, anemia, or blood disorder. It can help diagnose whether you have hepatitis, fatty liver, and cholecystitis.

Adjunctive diagnosis of nephritis and nephrotic syndrome. As an adjunct to cerebrovascular disease in hyperlipidemia and metabolic syndrome. Routine blood test is a common test item in clinical laboratories.

It mainly helps to check white blood cells, red blood cells, platelets, hemoglobin and five-cell differential, etc. When the corresponding value of the test result is above or below the normal range, it means that there are some corresponding diseases in the body.

If only routine blood tests are done after the blood test, then during this procedure, doctors usually only test for red blood cells, white blood cells, platelets, hemoglobin, etc. Through these materials, the doctor can tell if the person is suffering from anemia, infections, or other blood disorders. This is a very basic test.

If some abnormalities are found, more in-depth tests may be needed to determine the condition.

Blood tests can detect anemia, infections, and blood clotting problems. Most people know that a blood routine is the most basic blood test. The project mainly focuses on the specific detection of red blood cells, white blood cells, hemoglobin, platelets and other substances in the human body.

Although the blood routine is a very routine examination, it can intuitively see whether a person is anemic, whether there is an infection, and whether there is blood clotting, so the blood routine is also a very important examination.

When testing liver function in this way, the main thing is to determine whether the person's liver function is impaired, whether there is hepatitis infection, and even clearly see the extent of infection. If kidney function is checked through blood biochemical tests, it can be checked whether the person's kidneys are damaged and whether some of the corresponding functions can function properly. In general, if a high level of total cholesterol and esters in the blood is detected after a blood draw, then this causes dyslipidemia, and a blood draw can diagnose hyperlipidemia.

A fasting test is required, and fasting blood sugar levels are the gold standard for diagnosing diabetes, so we can also check for diabetes by having blood drawn.

The blood routine can determine whether you have inflammation or viral infection, and you can also know whether you have allergies, in fact, you can also know whether you have anemia and blood system diseases. If you take blood to check your blood sugar, you can know if you have diabetes or hypoglycemia. If you do a blood lipid test, you can know if you have hyperlipidemia.

If the liver function is checked by a blood test, then it is possible to know if there is a liver disease.

Hyperthyroidism, anemia, kidney function, viral infections, AIDS, and leukemia can be detected through blood tests.

There are many problems that can be detected, the most common ones are high blood pressure, hyperlipidemia, leukemia, etc., and now blood tests can also find out if you have cancer.

Anemia, hepatitis, syphilis, viral screening, leukemia, respiratory infections, these diseases can be detected, and it is a good habit to have regular medical checkups.

1. White blood cells.

White blood cells can kill invading germs, and when the amount of white blood cells in the body is too high, it may be that the body has developed inflammation or bacterial infection. The specific site of infection should be analyzed in combination with other symptoms, such as cough and phlegm, then it may be the lungs; If the ear is draining pus, it may also be otitis media; If the lymph nodes are swollen all over the body, then it may also be a malignant blood disorder.

2. Neutrophils.

Neutrophils have phagocytic and bactericidal effects, and an increase or decrease in their number will have a significant impact on the body. If the neutrophil count is too high, problems such as acute purulent infection, acute bleeding, and malignant tumors may occur. If the neutrophil count is too low, problems such as typhoid, measles, and influenza may occur.

3. Lymphocytes.

Lymphocytes are actually a type of white blood cells, which have the function of immune recognition, and are divided into T lymphocytes, B lymphocytes and natural killer cells according to their specific functions. The increase in lymphocytes generally means that the body has developed infectious diseases, blood diseases, etc., and some organ transplant patients may also have this condition, which is a rejection reaction after organ transplantation.

4. Eosinophils.

Acidphagocytes are further divided into growth hormone cells and prolactin cells, which are a type of cells that appear in the parathyroid glands after puberty. If the number of these cells increases, it is likely to be caused by allergies or parasitic infections.

5. Red blood cells and hemoglobin.

Routine blood tests for patients with anemia will show a significant decrease in red blood cells and hemoglobin, and doctors will be able to confirm whether the patient has anemia through some physical examination and laboratory tests.

6. Platelets.

Platelets can form hemostatic embolism, which has the function of blood clotting, and if the value of platelets changes, it often means that there is a problem in the body. Thrombocytosis is common in iron deficiency anemia, myeloproliferative disorders, cancer and other diseases, while thrombocytopenia is common in aplastic anemia, acute leukemia, and giant platelet syndrome.

Blood health is the foundation of good health. Blood is an important part of the human body, and the physiological and pathological changes of various organs of the human body often cause changes in blood composition. The public medical examination expert will introduce you to what items are included in the blood test.

Blood tests include blood routine tests, blood lipids, blood rheology, blood glucose and other tests. Among them: routine blood tests include:

Check for anemia, inflammation, blood diseases, etc. Red blood cell count (RBC), white blood cell count (WBC), platelet count (PLT), hemoglobin (HGB), intermediate cell count (MID), lymphocyte count (Lymph), granulocyte count (gran), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCC), mean platelet volume (MPV), red blood cell distribution width (RDW), hematocrit (HCT) A total of 18 test results were performed, platelet distribution width (PDW), platelet hematocrit (PCT), lymphocyte percentage (lymph%), granulocyte percentage, and intermediate cell percentage (mid%). Anemia, inflammation, abnormal hemostasis, hematologic diseases, liver and spleen lesions, and temporary infection can be found.

Lipid profile: Lipid profile is a quantitative method for the determination of lipids contained in blood (plasma). Commonly used tests generally include:

Determination of total cholesterol resistant bond and cholesteryl ester, determination of triacylglycerol, determination of lipoprotein fraction distribution macros and subcomponents, etc. Blood health is the foundation of good health, do not wait until you are sick to check your blood, you should pay attention to the blood situation in time, therefore, regular medical check-ups are essential. Have regular medical checkups to ensure good health.

The People's Physical Examination Center is a professional health examination institution. For questions about physical examination, you can log in to the public physical examination**, consult with experts**, and make a quick appointment from the Internet. The public health examination has different physical examinations for different groups of people**.

Since everyone's physical condition is different, the specialist will prescribe a reasonable medical examination for your individual situation**. For details, you can contact the experts of the People's Medical Examination Center through the Internet, and the experts will help you choose the medical examination items. Ensure blood health, regular medical check-ups, and get rid of diseases.

Commonly used items are:

Blood examination can detect diseases of the blood system and the function of other organs around the body, through blood examination, blood system diseases can be seen anemia, granulocytopenia, hemoglobin reduction, platelet dysfunction, aplastic anemia, coagulation function, hematopoietic hypofunction, these can be obtained through blood examination. The dysfunction of other organs around the body can also be detected by blood tests, such as doing all biochemical tests to find out whether liver function, kidney function, diabetes, blood uric acid is high, and heart function. Rheumatism can be seen by checking the rheumatism series, the immunity level of the whole body can be seen by checking the full range of self-immunity, and the thyroid series can be checked to see if there is a problem with the thyroid gland.

1. Routine blood examination, you can know the total number of white blood cells, neutrophils, lymphocytes, platelets, hemoglobin, etc.

2. Extract all items of biochemistry, be able to understand blood sugar, liver function, kidney function, blood lipids, electrolytes, etc.

3. Blood sampling can also check for hepatitis B, hepatitis C, hepatitis A, etc.

Fourth, endocrine problems, such as the function of the thyroid gland, are all done through blood tests.

Diseases that can be detected by blood lipids: hyperlipidemia, hypolipidemia, etc., and can help prevent coronary heart disease.

As the name suggests, a lipid test is a procedure that examines lipids in the blood by drawing blood. This test not only screens for lipid diseases such as hyperlipidemia and hypolipidemia, but also includes indicators such as high-density lipoprotein, low-density lipoprotein, apolipoprotein A, apolipoprotein B, and apolipoprotein E, so regular blood lipid tests can help prevent coronary heart disease and Alzheimer's disease.

2. Complete blood routine. Detectable diseases: anemia, infections, and blood clotting problems.

Routine blood tests are the most basic blood tests. However, it is mainly an item that examines substances such as red blood cells, white blood cells, hemoglobin, and platelets. Therefore, this most basic test can be used to comprehensively check for diseases such as anemia, infection, and blood clotting.

3. Diseases that can be detected by ESR: for judging various inflammation, tissue damage and necrosis, malignant tumors, anemia and hypercholesterol overture, etc.

Liver, kidneys, and so on. Usually, it is just a check for infectious diseases.

？In order to ensure the accuracy of the examination results, some problems should be paid attention to before the blood test, and because the blood test is the first step in doing a health examination, maintaining a stable state of mind is conducive to the accuracy of the examination results. The day before the blood test, it is best not to eat high-protein and oily foods and not to drink alcohol, because these foods and alcohol will directly affect the proportion of blood components, which in turn will affect the results of the test.

Ask your doctor for different laboratory tests and treat them differently. Before the lipid test, it is best not to eat foods that are too high in fat, such as pork rib soup, tamales, etc. At the same time, on the day of blood drawing, do not wear clothes with cuffs that are too small or too tight, so as to avoid the sleeves not being rolled up during the blood draw or the sleeves being too tight after blood drawing, causing hematoma of the arm blood vessels.

In general, blood tests are performed on an empty stomach, such as liver function, sugar, protein, lipids, and various inorganic ions (potassium, sodium, calcium, phosphorus, etc.). Blood can also be collected 6 hours after a bland diet when special needs are required, but blood must be collected 12 hours after a meal when doing a lipid test. People have a blood sugar rise after eating and gradually return to normal after about 2 hours, so blood sugar tests need to be done on an empty stomach.

The same is true for blood lipid analysis, because chylomicrons can appear after eating, which seriously affects the measurement results, so fasting for more than 12 hours is required to draw blood. There are three major issues to be paid attention to in the blood test, no greasy on the day before the blood draw, an empty stomach on the morning of the blood draw, and loose clothes. At the same time, there are some other matters that you need to pay attention to after the blood test, so as to ensure the quality of the blood and the accuracy of the physical examination.

Health examination of Beijing ** Hospital.

I got it. Blood tests can be done to test liver function, venereal diseases, AIDS, whether you are pregnant, whether you are pregnant, whether you are pregnant, whether you are taking drugs, etc. In the laboratory of the hospital, there are often many patients taking blood tests, and some blood are drawn from the veins of the arm to test liver function; Some of them test red satin or white blood cells from the blood on the fingers, and there are many items!

Why do these patients have to take blood tests? Because blood tests can help diagnose diseases. It turns out that the blood vessels of the human body are like rivers that extend in all directions, distributed throughout the body, and blood is river water, and blood is a red viscous liquid, composed of plasma and cells.

There are many substances such as proteins, enzymes, carbohydrates, fats, inorganic salts and other substances in plasma, and the content of these substances usually has a certain normal range; The cell part has red blood cells, white blood cells, platelets, etc. The various components in the blood have their own roles. When the body is sick, certain ingredients are changed in quantity and quality.

Red blood cells are like the transport of personality, which is responsible for transporting fresh oxygen to the body, without muscles, nerves, and bones to work normally, and bringing carbon dioxide to the lungs, and excreting it from the body, once for some reason, the number of red blood cells decreases or hemoglobin decreases, the transportation capacity will be reduced, and the oxygen needed by all parts of the human body will not be satisfied, and people will have symptoms such as shortness of breath, dizziness, and weakness of limbs. Based on these symptoms alone, doctors often cannot conclude that it is caused by anemia, because some diseases can also have this symptom. If the number of red blood cells decreases or the hemoglobin decreases, the doctor can diagnose anemia and do other blood tests to find out the type of anemia so that the symptoms can be corrected**.

Another example is white blood cells, under normal circumstances, 5,000 10,000 per cubic millimeter, once the germ invades, the white blood cells will surround and destroy the bacteria under the command of the central nervous system. If the germs that invade the body are more numerous and stubborn, the number of white blood cells in the blood will increase to engulf the germs, and the patient will have symptoms such as fever or local inflammation. The doctor can make a correct diagnosis based on the increase in white blood cells and the number of white blood cells increased, combined with the patient's symptoms. Blood tests can not only help diagnose the disease, but also help the doctor observe the results.

For example, diabetic patients, the sugar content in the blood begins to exceed the normal by a lot (the normal value is 80 120 mg per 100 ml of blood), and after **, it gradually decreases, and sugar no longer appears in the urine, indicating that ** is effective.
