What diseases can be detected by a physical test? Can a blood draw detect any disease?

First of all, we have to know which items are checked in the physical examination, blood routine and biochemical items are essential, generally speaking, tumor markers, thyroid function five items are also available, coagulation, D dimers, etc.

First of all, let's talk about the blood routine, we generally look at the three lineages, namely white blood cells, red blood cells and platelets, which can reflect whether a person has an infection (bacterial infection or viral infection), anemia (mild, moderate, severe) or blood diseases, such as leukemia, aplasia, thrombocytopenic purpura, etc.

Biochemical items, including liver function, kidney function, electrolytes, blood lipids, blood sugar and cardiac enzymes, can reflect whether the patient has abnormal liver function, jaundice, hypoproteinemia, creatinine and uric acid increases, hyperlipidemia, diabetes and whether heart function is impaired, etc.

Tumor markers, generally speaking, are 7 tumors, and if one of them is very high, it can reflect the tendency of tumors in the gastrointestinal tract, pancreas, ovaries, liver, etc.

The five items of thyroid function can reflect whether the patient has hyperthyroidism or hypothyroidism.

Overall, a physical examination blood draw can detect a lot of problems, and of course no abnormalities are better. However, it is recommended that you should have a regular medical check-up once a year, which is important in preventing or early detection of certain diseases.

This should be determined according to different physical examination items, and the current domestic physical examination and blood sampling items are not exactly the same, and there are several items that are mostly available, as follows:

Routine blood count includes complete blood count, hemoglobin concentration and distribution, and more. Erythrocytosis or anemia, leukocytosis or hypocytosis, and thrombocytosis or hypocytosis may be detected. If there is anemia, it is also possible to distinguish whether it is microcytic hypochromic anemia or macrocytic anemia, the former may be related to iron deficiency, and the latter may be related to vitamin B12 and folic acid deficiency.

Iron deficiency anemia may also indicate the possibility of gastrointestinal blood loss and tumors. Changes in the number of blood cells can provide clues to the diagnosis of leukemia and liver disease.

Can help determine the presence of chronic hepatitis B.

Suggests chronic renal impairment. Patients with high blood pressure and diabetes are especially careful.

Indicates the presence or absence of diabetes mellitus and hyperlipidemia.

Most of the liver function tests, renal function and blood glucose and lipids in the above two are in the same laboratory sheet, collectively referred to as blood biochemistry.

This section varies widely, with some having only two or three items, while others have as many as nearly ten. But its value has yet to be verified, and both false positives and false negatives are problematic.

It's not routine, for menopausal women and otaku otaku, it should be a must, and if it's low, it needs to be supplemented.

This cannot be generalized, especially different physical examinations have different blood test items, such as the most routine physical examination ** blood test items are blood test routines, liver and kidney lipid function, and some items that are not blood tests (such as urine routine, stool routine, electrocardiogram, heart color ultrasound, hepatobiliary, spleen, pancreatic and kidney color ultrasound, chest X-ray, etc.).

And if you choose a more expensive physical examination**, it may also include a full set of tumor tests, thyroid function tests, coagulation tests, hepatitis B full set and so on. These can be roughly screened for tumors, thyroid disease, hepatitis B, etc.

Among them, the blood routine can determine whether there is infection, whether there is anemia, whether there is thrombocytopenia, etc.

Liver and kidney lipid function tests can be used to screen for abnormal liver function, hyperlipidemia, renal insufficiency, hyperuricemia, and normal blood sugar levels.

Simply saying which diseases can be detected by physical blood testing, this cannot be determined, it can only be screening, and the blood test results need to be combined with other examinations and clinical symptoms to comprehensively judge the results.

Blood is a tissue that circulates in the circulatory system, in the heart and in the lumen of blood vessels. Composed of plasma and blood cells. Plasma contains various nutrients such as plasma proteins and lipoproteins, as well as inorganic salts, oxygen, hormones, enzymes, antibodies, and cell metabolites.

The physiological and pathological changes of organisms often cause changes in blood components, so the detection of blood components has important clinical significance. Blood tests are required for many conditions, including genetic conditions.

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.

Blood tests during a physical examination are usually routine blood tests and biochemical tests.

Blood tests can be done to test liver function, sexually transmitted 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 of them draw blood from the vein of the arm to test liver function; Some test red blood cells or white blood cells from the finger blood, and there are many items.

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.

Why does the hospital have to draw blood when I see a doctor? What did the blood go for? Tell you about it today.

If the blood is drawn from a vein in the arm, this test is also called biochemistry. You can find out many indicators of the body, such as whether your body's vitamin content is up to standard, calcium, iron, etc., blood lipids, uric acid, and blood sugar indicators? Then there is whether there is inflammation in the body, for example, um, albumin, urine protein, etc.

In short, biochemistry is the main basis for detecting whether many physical indicators are up to standard.

There are many items of blood test, such as blood routine, liver function, kidney function, thyroid function, blood test can reflect the functional status of many organs in the body, but not all diseases can be detected, it can only be said that many diseases can be detected, and the doctor prescribes blood tests for you, all for a purpose.

Blood tests can timely understand your liver function, kidney function, thyroid function and all aspects of the body's indicators, detect diseases in time, and get good prevention and**.

Blood draws can detect many diseases, which need to be decided depending on the item of the blood draw. For example, a blood routine can detect diseases such as anemia and infection, as well as leukemia. Liver function can detect whether there is liver function damage, and it can also reflect whether there is bile duct obstruction.

A lipid test can be done to check for hyperlipidemia. Checking the kidney function can also show whether there is hyperuricemia, renal insufficiency, kidney failure, etc. Thyroid function can reflect the presence or absence of hyperthyroidism and hypothyroidism.

Electrolyte testing can reflect electrolyte abnormalities such as hyperkalemia, hypokalemia, hypernatremia, hyponatremia, and hypercalcemia. Tumor markers can also be looked for, which indicate whether there is a potential risk of having a tumor in the body. Blood draws can also check blood sugar and check for diabetes.

There are many items that can be drawn for blood, and there are many diseases that can be reflected. However, blood tests are sometimes not the gold standard, and it needs to be combined with other tests and the patient's symptoms to diagnose the disease.

There are many diseases that can be detected by blood drawing.

When I go to the hospital to see a doctor, I often take blood for examination, why do I have to draw blood when I see a doctor? What diseases can be detected by having blood drawn? When there is something wrong with the body, the balance in the blood is disrupted, and there will be abnormalities in the blood, so it is necessary to check the blood in many cases, and blood drawing can detect three aspects of the disease.

Blood tests can detect most diseases in the human body, but what diseases can be detected by blood tests?

Blood tests can detect many diseases because they are an important means of detecting diseases. For example, the blood routine can look at hemoglobin and white blood cells. If hemoglobin is significantly low, consider whether there is anemia.

The white blood cells are significantly increased, and combined with chest x-ray, PCT, C-reactive protein, etc., it is possible to see if there is a bacterial infection or a lung infection. Blood tests can also look at blood lipids, total cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein, etc., if abnormal, it is hyperlipidemia.

If lymphocytes are high, a viral infection is usually considered. Eosinophils, sometimes associated with allergic reactions. The other main ones are red blood cells and hemoglobin.

Mainly check for anemia. and the types of anemia. and platelets.

The condition of platelets reflects the body's clotting mechanism.

Physical examination blood is a very common phenomenon, so what is the specific physical examination blood test?

Physical blood tests are mainly done to check the following, blood sugar, including fasting blood glucose and glycosylated hemoglobin. Blood lipids, including cholesterol, triglycerides, cut-off proteins. Routine blood count, including hemoglobin, red blood cells, white blood cells, platelets, neutrophils, etc.

Liver function, liver function includes alanine aminotransferase, aspartate aminotransferase, total bilirubin, direct bilirubin, indirect bilirubin. Kidney function, kidney function includes urea nitrogen, creatinine, uric acid. Tumor markers, including CA199, CA153, CN125, etc.

The routine blood examination generally includes three aspects. One aspect is white blood cells. White blood cells are the body's guardians and embody an immunity of the body.

White blood cells include neutrophils, eosinophils, lymphocytes, etc. Bacterial infection is usually considered when the total number of white blood cells is high and neutrophils are also high.

It is generally believed that blood tests may only be able to identify diseases related to blood, but in fact, no, there are many diseases that can be seen.

1.Infectious diseases: Under normal circumstances, there are no bacteria in the blood, and in severe systemic infection, bacteria multiply in the blood, and when bacteremia or even toxemia occurs, there can be continuous high fever and chills.

2.Metabolic diseases: Many improper lifestyle habits can cause metabolic disorders of sugar, lipids and proteins in the body, and diabetes, lipid abnormalities, hyperuricemia and other indicators such as blood glucose, triglycerides, cholesterol and uric acid are found.

4.Hematologic diseases: For example, abnormal leukocyte hypersensitivity can be seen in leukemia, myeloproliferative diseases and malignant tumors, when the leukocytes in the body proliferate malignantly, it will affect the normal hematopoiesis of the bone marrow and produce a large number of leukemia cells.

Low red blood cells and hemoglobin can be seen in various pathological anemias.

6.Liver and kidney diseases: through the abnormalities of kidney metabolites such as creatinine and urea nitrogen, glomerular filtration function and other problems can be found, so as to further examine and diagnose kidney diseases; When the liver is damaged, liver cells are destroyed and transaminases are released, resulting in elevated transaminases in the blood, which can detect liver disease.

7.Rheumatic immune diseases: When there are rheumatic immune system diseases such as systemic lupus erythematosus and rheumatoid arthritis, abnormalities can be found through autoantibodies, complement, cytokine tests and other indicators, and help in diagnosis, ** and prognosis assessment.

When you get the physical examination form, you will see that the precautions for the physical examination are written "fasting after 10 o'clock the night before the blood draw", and many people are afraid of affecting the accuracy of the physical examination results, and they don't even dare to drink water. In fact, this is a misunderstanding, you can drink a small amount of water for fasting blood drawing, generally no more than 200ml, but you can only drink plain water, so as not to affect the results of abdominal ultrasound (gallbladder) examination.

Do not do a lot of exercise in the first 3 days of blood drawing, due to energy consumption, body fluid loss, and strenuous breathing during exercise, the levels of alanine aminotransferase, aspartate aminotransferase, creatine kinase, lactate and glucocorticoids can be temporarily increased, which will affect the authenticity of the test results.

Keep an empty stomach before the blood draw, except for some medications that must be taken on time, such as antihypertensive drugs, and try to move other drugs until after the blood draw. This is because certain chemical components in the blood change after eating food or taking medication, which can affect the results of the test. At the same time, it is advisable to follow the hospital's arrangement in the morning blood collection time so that the test results can be obtained in time.
