How to get tested for tuberculosis How many days does it take?

At present, tuberculosis laboratory examination technology has also developed by leaps and bounds, mainly focusing on the detection of bacteriology and related indicators (immunology, molecular biology), and the diagnosis of tuberculosis can be confirmed if Mycobacterium tuberculosis is found in sputum, which is also an important basis for choosing chemotherapy regimens and judging efficacy. It takes 4 to 8 weeks to culture TB bacteria, but it is sensitive and accurate. In recent years, polymerase chain reaction (PCR) technology has developed rapidly and has been used for the detection of tuberculosis pathogens, which has solved the rapid detection of tuberculosis, and at the same time, erythrocyte sedimentation rate, blood routine, active enzymes (such as ADA) and detection of tuberculosis antibody (TBAB) in serum have reference significance for diagnosis.

In addition, bronchoscopy and thoracoscopy, lymph node puncture or biopsy, lung biopsy and chest biopsy, and pathological examination are all helpful in the diagnosis and differential diagnosis of tuberculosis.

Examination should include a chest x-ray and a PPD test. Culture of sputum bacteria for tuberculosis. Go to your local Centers for Disease Control tuberculosis clinic. You explain the situation to them, and the filming is free. Chest X-ray can sometimes be missed. The total inspection time takes 72 hours.

If tuberculosis is suspected, first check the chest x-ray ESR, and when pulmonary tuberculosis is suspected, ask the doctor to open a referral form to the epidemic prevention station to check PPD, sputum smear (for 3 days), and sputum culture! Only the sputum culture takes a long time, and the rest only takes 3-4 days to get it!

Specifically, there are symptoms of tuberculosis, such as low-grade fever and night sweats, fatigue, loss of appetite, any kind, do a blood test, generally mainly to see the value of erythrocyte sedimentation rate, in the tuberculosis antibody test, as well as tuberculin test (only as a basis for diagnosis has no specificity), as well as X-ray examination, or CT MRI examination, generally experienced doctors can diagnose whether it is tuberculosis infection in imaging, in is based on the patient's medical history, whether there is a history of tuberculosis, and a history of trauma, In order to rule out other diseases! An accurate diagnosis is made based on a combination of the above tests and medical history.

Main Common Symptoms of Tuberculosis As with other diseases, the early stages of tuberculosis are asymptomatic because the lesions are small. In addition, even if symptoms are present, patients and doctors tend to mistake them for other diseases and ignore them because the symptoms of tuberculosis are not distinctive. Through many investigations and analyses, the main symptoms of tuberculosis are:

Cough and sputum for more than 3 weeks Hemoptysis Fever or chest pain for more than 3 weeks After having the above symptoms, you are a "person with suspicious symptoms of tuberculosis" and should think about whether you have tuberculosis. It is best to go to a tuberculosis clinic or a tuberculosis specialist hospital first. In addition to a chest x-ray, it is important to do a sputum tuberculosis test.

Because the detection of tuberculosis bacteria means that the pathogen has been found, the diagnosis can be confirmed. Early and correct diagnosis is the first condition for tuberculosis. The main diagnostic methods of pulmonary tuberculosis.

1. Sputum tuberculosis examination: (1) Sputum smear examination. The sputum tuberculosis bacteria test is simple and easy, and the accuracy is high, and the tuberculosis bacteria can be detected in the sputum, and the diagnosis of tuberculosis can be confirmed.

Generally, three sputum specimens are examined at the initial visit, i.e., nocturnal sputum, early morning sputum, and immediate sputum. It is a diagnosis of tuberculosis though"Gold indicator", but the low positivity rate is a fly in the ointment. (2) Sputum tuberculosis culture, the results are highly reliable, and the antimicrobial susceptibility test of tuberculosis can be done, but it takes 6-8 weeks, and the application is limited.

2. Chest examination can not only detect tuberculosis early, but also determine the location, nature and scope of the lesion, understand the incidence and use it to judge the effect, and it is convenient to carry out and patients are willing to accept it. Chest CT can detect small or hidden lesions, which can compensate for the lack of general examination.

3. Immunological diagnosis of pulmonary tuberculosis: 1. The commonly used tuberculin pure protein derivative (PPD) test, which is positive is one of the evidence of tuberculosis infection. 2. Positive tuberculosis antibody test in blood and sputum is also helpful for diagnosis.

3. Patients with severe pulmonary tuberculosis may have abnormal endocrine examination. 4. The metabolites of Mycobacterium tuberculosis can be isolated in two weeks, but the amount of bacteria can affect the number of days of positive results. 5. Polymerase chain reaction (PCR) has poor specificity, and the advantage is that the sensitivity can reach 98% 100%.

4. Other examinations 1. Flexible bronchoscopy: bronchial and pulmonary lesions can be directly observed or indirectly judged, and there are functions such as biopsy, lavage, video, and endotracheal shooting, which are particularly useful for diagnosis and differential diagnosis. 2. Thoracoscopy and mediastinoscopy

Both can be used to observe enlarged lymph nodes in the chest cavity and mediastinum, and can be removed for biopsy to facilitate diagnosis and differential diagnosis. 3. Ultrasound examination: mainly used for the diagnosis and differential diagnosis of pleural effusion.

Go to the CDC for an X-ray and sputum culture! Infiltrating free**.

Just go directly to the local epidemic prevention station to check, no money.

Just go to the Centers for Disease Control and Prevention to test your sputum.

1.Chest x-ray or chest CT to determine the location, size, and morphology of lung lesions;

2.Sputum was examined for acid-fast bacilli and sputum culture, blood anti-tuberculosis antibody erythrocyte sedimentation rate and PPD test were checked;

3.If the sputum bacteria are positive, the diagnosis of tuberculosis can be confirmed, and if the sputum bacteria are negative, a diagnostic anti-inflammatory ** chest x-ray or chest CT is required half a month later, and compared with the original film, if there is no change in the lesion, it is tuberculosis.

4.Check liver and kidney function, if normal, can be anti-tuberculosis**.

Hope mine can help you.

Chest X-ray. To put it simply, it's an X-ray, and I wish you a happy day!

Blood tests and sputum tests can be done with CT.

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.

Three tests are done, namely an OT test, sputum for tuberculosis bacteria, and a chest x-ray.

Diagnosis of pulmonary tuberculosis requires a strong positive OT test and a positive sputum test for bacilli,+

Lung x-ray features. (All three must exist at the same time).

There are many diagnostic methods for pulmonary tuberculosis, mainly including tuberculin test, tuberculosis antibody, pleural effusion examination, bronchoscopy, cytology, sputum examination for acid-fast bacilli, etc.; Acid-fast bacilli in sputum are the gold standard. This is followed by pathological examination.

PPD test needle, sputum test, chest CT, blood recombination symptoms.

I've had it before, and it's been checked out by filming.

Question 1: When will I get the results of the tuberculosis test? There is a result on fluoroscopy on the same day, and the next day, sputum and blood tests (liver function, etc.) are tested, and fasting is required before the examination. Diagnosis is usually made in 1-2 days.

Question 2: If I go to check in the afternoon, how long will it take for the results of the tuberculosis examination to come out The most obvious is the appearance of blisters and ulcers and pus and blood in the red and swollen areas At this time, it can be directly concluded that there are active tuberculosis bacteria, and there are hard joints in the red and swollen area, and when the diameter of the measurement exceeds 2 cm, it means that there are active tuberculosis bacteria.

Question 3: How long does it take to check for pulmonary tuberculosis Most patients are found by chest X-ray or X-ray during physical examination, if pulmonary tuberculosis is suspected, sputum examination, CT, PPD test, knotting test, pathological biopsy and other related examinations can be done, and combined with symptoms to diagnose. How long it takes to get results depends on what tests you do.

Question 4: How long does it take to get a report for a UK visa tuberculosis test If you have a standard test and your chest X-ray is normal, you will get your test results and proof in no time. If the test results are inconclusive, you will need to undergo further sputum sample testing.

The test takes two months to get results. If the test result shows that you are not infected with tuberculosis, you will be issued with a certificate, which you will need to submit with your visa application. The certificate is valid for 6 months.
