Is a chest x ray accurate for tuberculosis?

X-ray chest X-ray can make an impression diagnosis based on the location and shape of the lesion, and the diagnostic coincidence rate is very high, about 85-95%, but it is not 100% accurate. If there are no other symptoms, tuberculosis cannot be ruled out, because the symptoms of tuberculosis are atypical, and the typical symptoms appear one after another with the development of the disease, and there can be no conscious symptoms in the early stage of the disease.

You go to a professional institution to have a look, professional institutions are very experienced in this, as long as it is tuberculosis, it will not be without sputum, if acid-fast bacilli are found in the sputum, it can be diagnosed, because bacteriological positivity can be used as the basis for diagnosis.

No symptoms does not mean that there is no tuberculosis, one of my patients is also asymptomatic, this is because her condition is still mild, if it continues to develop, not in time, the symptoms will become more and more obvious, and it may be related to resistance, strong resistance, some people can be cured without treatment, after people are infected with tuberculosis bacilli, when the resistance is strong, often will not get sick, tuberculosis bacilli will first hide, and wait until the resistance declines in the waves. Chest X-ray is not accurate, can not be said one-sidedly, chest X-ray clarity is not as good as chest X-ray, better or CT, no matter how good there is MRI, (but CT can be done) Tuberculosis is also an inflammation, so it is easy to be misdiagnosed as pneumonia, (I am a case) It is best to go to a specialized hospital to check it to confirm whether it is or not, this disease can not be delayed, the more delayed, the more serious, the more difficult it is to treat, and it will harm others and yourself. There are tuberculosis epidemic prevention stations in all places, and there are free medicines there, but some people take those medicines that don't work, and the amount of drugs is large, *** large, don't be greedy for small and cheap and suffer big losses.

If possible, or go to a specialized hospital, strengthen ** for a period of time, and then go home to recuperate, sputum test is to check whether there are tuberculosis bacteria in the sputum, whether it is infectious, and the examination of tuberculosis and PPD is similar to the skin test, to check whether it is infected. Remember, don't delay, or the disease will stay with you longer. Delay study, delay work.

Diagnosis of tuberculosis is currently based on imaging tests. Chest X-ray is diagnostic. But it's better to get a chest X-ray again. This is also conducive to comparison in the future review.

I have tuberculosis, there are fewer misdiagnoses of tuberculosis in general hospitals, the symptoms you said are terrible, and then there are people whose symptoms are not obvious, but you had better find acid-fast bacilli in a sputum test, for 3 consecutive days, 10 yuan a day, and a blood sedimentation rate test, which is also very cheap. CT can also be doneIf yes, don't delay, don't be afraid, hurry**.

Isn't it better, find out, it's 100 times better than delaying! I had tuberculosis in my kidneys, and I had one removed.

The common symptoms of tuberculosis are: weight loss, low-grade fever in the afternoon, night sweats, cough and sputum, and sometimes blood in the sputum. A chest x-ray or CT may be more accurate.

What is a chest X-ray done to check for? Half an hour after a chest X-ray can show an increase in the rate of chromosomal aberrations and micronucleus due to the erroneous repair of DNA damage caused by X-rays. X-rays acting on the erythrocyte membrane may reduce the number of charges on the membrane and reduce the enzyme activity, thereby reducing the ability of the C3B receptor on the erythrocyte membrane to clear pathogenic immune complexes, and also causing changes in lymphocyte glycogen metabolism.

There is a statistically random effect between carcinogenicity and genetic disease caused by low doses of nuclear radiation, the severity of which is not affected by the size of the absorbed dose, but the probability of carcinogenicity is related to the size of the dose, and there is no dose threshold. According to the latest research results of the International Commission on Radiological Protection, about 350 people in cities with a population of about 10 million people may develop cancer, leukemia or other genetic diseases each year due to X-ray exposure.

1) Bacteriological examination:

1) Sputum smear examination: sputum smear examination is simple and easy, and at present, tuberculosis prevention and control institutions at or above the county level in China, including some township sputum inspection points, have carried out free sputum smear examination for patients with suspicious symptoms of pulmonary tuberculosis. China's tuberculosis prevention and control program requires all patients with cough, sputum production for 3 weeks, or hemoptysis or bloody sputum sputum microscopy to undergo sputum smear.

2) Sputum Mycobacterium tuberculosis culture, the results are highly credible, and can do tuberculosis drug susceptibility test, but ordinary culture takes 6-8 weeks, rapid culture has higher requirements for equipment, and is more expensive.

2) Molecular biology examination.

Polymerase chain reaction (PCR), sensitivity can reach 98% to 100%, but false positives are common.

3) Immunological examination.

1) The tuberculin test is commonly used, and a positive test is one of the evidence of infection with tuberculosis bacteria. It has certain auxiliary significance in the diagnosis of tuberculosis in children.

2) A positive serum test for anti-tuberculosis antibodies is also helpful in diagnosis.

4) X-ray examination.

It can determine the location, nature and scope of the lesion, understand the onset of the disease and use it to judge the best effect, but the accuracy of the diagnosis is largely determined by the doctor's level. Chest CT can detect small or hidden lesions and can compensate for the shortcomings of general x-rays.

At present, in China, tuberculosis prevention and control institutions are conducting free chest X-ray examinations for patients with suspicious symptoms of pulmonary tuberculosis.

5) Other examinations.

1) Fiber bronchoscopy: tracheal and bronchial lesions can be directly observed, and combined with biopsy pathological examination, it is helpful for diagnosis and differential diagnosis.

2) Ultrasound: mainly used for the localization of lesions.

The diagnosis of pulmonary tuberculosis should be based on sputum to find positive tuberculosis bacteria and rapid erythrocyte sedimentation rate, chest x-ray suggests that there are tuberculosis foci in the common site of tuberculosis, etc., and combined with clinical symptoms. If necessary, a shadow biopsy biopsy of the lungs is performed to determine the pathologic nature.

CT can only see the shadow of the lungs and the edge of the shadow, but it is not tuberculosis and other tests need to be done, because you do not have typical symptoms such as cough, weight loss, and night sweats.

Then do some relevant tests to confirm what the lung imaging is. Sometimes people who have had tuberculosis do not know that they have not known at all, and after healing, the calcified lesions leave shadows, and they only find it during the physical examination, and this asymptomatic image should be ruled out.

If such a patient has no symptoms, it is recommended to have a follow-up examination at alternate intervals, but he does not know that he needs to have a spleen examination for tuberculosis. If you really feel uneasy, then take anti-tuberculosis drugs first, and then re-test after a month, if the tuberculosis will generally get better. Some tuberculosis is not clinically symptomatic.

At present, if the sputum smear and CT examination cannot confirm the diagnosis, other examinations will be even more powerless, even if the more evil T-spotTB (mixed lymphocyte culture interferon assay) advertised by various hospitals is ridiculously expensive, small 2,000, and the results can only be used as a reference, nor can it be diagnosed.

Generally, you should do a sputum smear and tuberculosis antibody first, if these two are negative, you can do a tuberculin test, if this is fine, there is no low-grade fever, cough, weight loss, fatigue, poor appetite and other symptoms, plus chest X-ray, CT problem is not big, basically can rule out the possibility of tuberculosis infection.

If chest X-ray or CT is suspected of pneumonia or tuberculosis, prophylactic ** can be carried out, first press pneumonia** for 2-3 weeks, and if the inflammation subsides, tuberculosis can be ruled out; **If the effect is not good, consider the problem of tuberculosis.

Tuberculosis should be tested for sputum, and sputum bacterial culture should be done.

CT should be able to find out!

In order to confirm whether it is tuberculosis, generally speaking, tuberculosis is symptomatic, such as fatigue, insomnia, night sweats, low-grade fever in the afternoon, cough, sputum production, hemoptysis, chest pain and dyspnea, etc., some people have no symptoms, which are checked out during the physical examination.

Regardless of whether there are symptoms or not, the diagnosis of pulmonary tuberculosis is mainly done with sputum smear, CT examination, once the diagnosis is confirmed, it must be timely**. When I went to check it that time, I encountered several people who had been suffering from tuberculosis for more than 10 years, and I didn't know if it was not cured at all or what. Later, after listening to a friend's introduction, I began to eat duck meat from the tuberculosis medicine duck formula, in addition to insisting on taking the medicine duck, I should also pay attention to rest, pay attention to balanced nutrition in terms of diet, take more lean meat, eggs, and soy products rich in animal protein, and put an end to alcohol and spicy food.

According to chest CT, sputum for acid-fast bacilli, tuberculosis test, tracheoscopy. Tuberculosis is a chronic disease, except for hemoptysis, pneumothorax and other comorbidities, no hospitalization**, free anti-tuberculosis drugs.

At present, tuberculosis is treated with free anti-tuberculosis drugs orally, without infusion, and tuberculosis patients with reduced immunity are prone to infection with other bacteria or drug-resistant bacteria when hospitalized, so there is no need to be hospitalized**. Chest x-ray, sputum examination, tuberculosis test, and tracheoscopy are usually done to determine whether tuberculosis is present.

The diagnosis of pulmonary tuberculosis is confirmed by looking for eosinophilus in the sputum, and if there is one, the diagnosis can be confirmed.

Blood test is only a way to assist in diagnosis, you can test for erythrocyte sedimentation rate, C-reactive protein and other tuberculosis drugs, and it is recommended to first take a radiograph to understand the condition of the lungs, if there are imaging changes in the lungs, you need to take blood to check for tuberculosis antibodies, anti-O, ESR, etc., and PPD tests are needed to confirm.

Tuberculosis is diagnosed by examination of the lungs, CT scans, and sputum cultures. The tuberculin test is a way to check for tuberculosis in the body. Blood is drawn to test liver and kidney skills.

Because many tuberculosis drugs cause liver and kidney damage, liver and kidney function should be checked before oral administration. Tuberculosis is a chronic wasting disease, so it is important to increase nutrition. Exercise in moderation. Indoor air should be circulated frequently.

Hello, blood draws generally do not check for tuberculosis-related items. Screening for pulmonary tuberculosis involves a small dose of medicine on the inside of the left forearm and a tuberculin test. Another way to screen for tuberculosis is to do a chest x-ray.

If you don't give you medicine and don't do a chest X-ray, you won't be able to find tuberculosis. There is an item called interferon release test, but it is more expensive, hundreds of dollars, and it is absolutely impossible to include this item in the general physical examination. It's too expensive.

Chest x-ray of active tuberculosis has typical imaging and can be initially screened.

A positive sputum culture in a patient with sputum confirms the diagnosis of tuberculosis.

If you do not cough or have phlegm, you can go directly to a tertiary hospital for tracheoscopy, and directly take samples from the lesion site for laboratory examination.

In addition, blood tests and PPD skin tests can also be used as auxiliary examination results.

Condition analysis: Hello, your situation belongs to the question of consulting the examination method of tuberculosis, and the general examination method of tuberculosis is mainly through sputum and.

PPD experiments.

Check as well. Chest X-ray examination to clarify the diagnosis Suggestion: In your case, I suggest that you should first pay attention to rest, strengthen nutrition, eat more eggs and meat, and blood tests will not detect tuberculosis, I wish you a speedy **.

The amount of radiation on a chest X-ray is the largest among X-rays, and one chest X-ray is equivalent to taking 10 X-rays**. However, chest X-ray examination is generally in tens of seconds, so the harm to the human body is very limited. There are few significant harms associated with a single chest X-ray in adults.

In the past decade, due to the improvement of X-ray equipment, the use of high kilovolt technology, image enhancement technology, high-speed sensitization screen and fast X-ray photosensitive film, the X-ray radiation has been significantly reduced, and the possibility of radiation damage has become less and less. Chest X-ray is mainly used to examine and diagnose lung diseases, the size of the heart, ribs, pleura, chest wall mediastinum, and bronchi. The use of X-rays to diagnose diseases is widely used in clinical practice.

The most common health check-up is a chest X-ray, and the most basic is a chest X-ray. Chest X-ray can show the soft tissues of the chest, bones (including the thoracic vertebrae), mediastinum (heart, large blood vessels, trachea, esophagus, etc.), trachea and bronchi, pleura, lung tissue, etc. It can diagnose congenital diseases of the lungs and trachea, such as abnormal development, various inflammations of the lungs, acute and chronic bronchitis, obvious bronchiectasis, emphysema or pulmonary edema, various types of tuberculosis, lung tumors, pleural effusion, pneumothorax, mediastinal tumors, abnormal heart morphology, etc.

Precautions for chest X-ray examination Chest X-ray is a routine examination item of physical examination, and the amount of radiation is the largest in X-ray examination, doing a chest X-ray is equivalent to taking 10 X-ray examinations, in order to reduce the damage of X-ray, patients should not do too much chest X-ray examination, and it is not appropriate to do many repeated examinations in a short period of time, especially in chest X-ray, do not blindly ask doctors to look at a little longer, look more carefully. In addition, pregnant women can not do chest X-ray examination, so as not to cause fetal malformations or miscarriage caused by radiation, etc., all women who have signs of pregnancy or have become pregnant must be cautious, if you must be examined by the radiology department, it is best to wear radiation clothing, protect the abdomen from the effects of radiation. It is also advisable for children to have fewer emission tests, and x-rays can be used instead of chest X-rays.

Chest X-ray is done to check for abnormalities in the heart, liver, and lungs, and most importantly, to detect tuberculosis. A chest X-ray can check for lung disease, the size of the heart, ribs, pleura, chest wall mediastinum, bronchi, etc.
