What’s tuberculosis test?


The tuberculosis test for TB infection is of two types. They are :

  • Skin test ( Mantoux tuberculin skin test)
  • TB blood test.


What’s tuberculosis?


  • Tuberculosis is a specific infectious disease.
  • It is caused by Mycobacterium tuberculosis.
  • Tuberculosis is the leading cause of illness and death around the world.
  • The mode of transmission is by inhaling tiny droplets of saliva from the coughs or sneezes of a person positive with TB disease.
  • Tuberculosis is an infectious airborne disease and a major public health problem.


Forms of tuberculosis:


There are mainly two types of tuberculosis

Pulmonary tuberculosis and extrapulmonary tuberculosis.


Global impact of tuberculosis


  •  44% of the new cases occurred in South East Asia, 24% in the African region, and 13% of the new cases in the Western Pacific Region in the year 2018.

Mode of transmission

  • If the patient positive with pulmonary TB coughs or sneezes, the droplets get into the air from the lungs.
  • Thus, it transmits through droplet infection.


The population at risk?

  •  Elderly, poor
  • Migrants, refugees, travelers
  • Smokers, chronic alcoholics
  • A person with diabetes, HIV/AIDS.
  • Sex: Males than female
  • Age group: 15-54 years.
  • Malnutrition.


Clinical features of tuberculosis


Some general symptoms of tuberculosis include

  • Chronic cough
  • Weight loss
  • Loss of appetite
  • Low-grade fever
  • Night sweats
  • Fatigue
  • Chest pain
  • Haemoptysis


Prevention of Tuberculosis


  • B.C.G (Bacille Calmette Guerin) Vaccination
  • Contains living bacteria from an attenuated bovine strain of tubercle bacilli
  • Danish 1331 strain is used for the production of BCG



  • 0.5 ml Intradermal
  • 0.05 ml to infants below 4 weeks


Differences between TB Infection and TB Disease


The differences between TB infection and TB disease are :

     TB Infection :

  •   Germs of TB do not multiply and don’t make us sick but they stay in our lungs.
  • TB infection is not communicated from one person to another.

   TB Disease:

  •  Germs of TB stay in our body, they start to multiply and they move to other parts of the body from the lungs and thus make us sick.
  • It is contagious and communicable.
  • If we do not treat TB infection then it will develop to TB disease.


What is the tuberculosis test?





There are two types of tuberculosis tests. They are :

  • Skin test ( Mantoux tuberculin skin test)
  • TB blood test.


The tuberculosis test is for the test of  TB infection. A health care provider does it by a skin test or by TB blood test both not both at the same time.


The skin test gives two results either positive or negative.


The TB blood test is either the positive or the negative:


Factors for selecting which tuberculosis test to use includes :

  • the reason for testing
  • cost and
  • test availability.



1.Skin test (Mantoux tuberculin skin test )


  • The tuberculosis skin test is performed by injecting a small amount of fluid which is known as tuberculin, into the skin on the lower part of the arm.
  • It requires two visits to the health care provider.He/she injects tuberculin in the first visit and reads the test on the second visit.
  • A person who is injected with tuberculin should visit health care providers within 48 hours to 72 hours to look for a reaction on the arm.
  • The tuberculosis skin test result depends on the swelling, raised, or hard area on arm.


The skin test gives two results either positive or the negative :


a.Positive skin test :

  • It means his/her body is infected with TB bacteria.
  • There is a need for additional tests to identify if the person has latent TB infection or TB disease.


b. Negative skin test :

  • It means his/her body is not infected with TB bacteria.
  • Similarly, it indicates that latent TB infection or TB disease is not likely.


The skin test is for the test of TB infection for children of age under five.


2.TB blood test :


  • It is also known as interferon-gamma release assays or IGRAs.
  • Two TB blood tests are approved by the US Food and Drug Administration(FDA)
  • They are available in the US: the QuantiFERON®–TB Gold In-Tube test (QFT-GIT) and the T-SPOT®.TB test (T-Spot).


For the TB blood test, a health care provider draws the blood of the patient and sends it to the laboratory for the analysis and results of the test.



The TB blood test is either the positive or the negative:


a.Positive TB blood test:

  • A positive TB blood test means there is the presence of TB bacteria in his/her body.
  • There is a need for additional tests to identify if the person has latent TB infection or TB disease.


b.Negative TB blood test:

  • A negative TB blood test means TB bacteria are absent in his/her body.
  • Similarly Negative TB blood test indicates that latent TB infection or TB disease is not likely.


TB blood test is for :

  • People who have received the BCG vaccine.
  • People who have a difficult time returning for the second appointment to look for a reaction of the Tuberculin Skin Test.


Frequently Asked Questions (FAQs)


What happens if you test positive for tuberculosis?

It means his/her body is infected with TB bacteria. There is a need for additional tests to identify if the person has latent TB infection or TB disease.

Why would someone need a TB test?

Someone needs a TB test to determine whether he has TB bacteria or not. There are two types of tuberculosis tests. They are the Skin test ( Mantoux tuberculin skin test) and TB blood test.

Urinary Tract infections are infections of the urinary tract.


The main symptoms of urinary tract infection are:
• A burning feeling when you urinate
• Frequent urination
Bacteria cause most urinary tract infection.


Health center generally cure urinary tract infection with antibiotics


Antibiotics suppress the growth of bacteria and kill it.


Older people generally test positive for urinary tract infection.


There is no need to do urine test for no clear symptom of urinary tract infection.


If the test in done without appearance of the symptoms it may bring another complication.



This complication is especially seen in older adults.


More complication results more cost of UTI antibiotics.


Following are some reasons of it:


Urine tests usually don’t help if you don’t have
UTI symptoms.


People of older age can have bacteria in their urine despite of the fact that they don’t have developed Urinary Tract Infection.


This fact is truly seen for nearly all of medical center residents.


Medical professional will suggest for  urine test if an older adult has clear symptoms of urinary tract infection,


UTI symptoms include  increased convolution , irritability, or dizziness.


The test has high chance of showing some bacteria.


For this purpose the antibiotics for urinary tract infection may be needed which costs from 50-500$.


Tests & treatments for urinary tract infections (UTIs) in older patients.


When you need them—and when you don’t ?


But if the bacteria is in the urine and not causing a real infection, the antibiotic won’t cure  the clear symptoms.


The reasons such as irritation, convolution fall may be symptoms of another disease so it need further testing.

How Often Should Health-Care Workers Be Tested For TB?

Introduction to health care workers tb test

Health-care Workers fall under high risk group to Tuberculosis (TB), due to their occupational exposure to infectious diseases. So it becomes essential to conduct testing of Health-Care Workers for TB infection.

The CDC (Centers for Disease Control and Prevention) and NTCA (National Tuberculosis Controllers Association) have created updated guidelines regarding TB screening and testing in Healthcare setups in 2019. These guidelines provide structural framework for the screening, testing, frequency of testing and preventive treatment for health care workers.


How Often And When Should The Health-Care Workers  Be Tested?

The updated guidelines made the following changes in terms of screening and testing:

  • Decrease in frequency of TB screening for the Health-Care Workers in various settings. Change in criteria of screening frequency changed.
  • Clear testing criteria of the health care professionals.

Guidelines for the frequency of testing and criteria of the testing of TB in Healthcare setting:

  • Baseline testing of health professional required. Annual additional tests are not performed if the exposure to the infection is null.
  • Interferon Gamma Release Assay (IGRA) or Tuberculin Skin Test (TST) with confirmed exposure to TB and who have no prior documented TB infection or Latent TB Infection (LTBI),
  • In personnel with newly positive test result, symptom evaluation and chest radiography with followup as indicated,
  •  Unless contraindicated, personnel with untreated Latent TB Infection encouraged to undergo treatment,
  • Annual symptom based screening for individuals with untreated LTBI,
  • The health professionals are provided with annual education on TB.


What Is TB Risk Assessment And How It Affects TB Screening Process In Health- Care Setups?

Risk Assessment is evaluation process to see the risk of transmission of Mycobacterum tuberculosis in a setting. The testing should be done even when there is no recent exposure to TB. Risk assessment is essential to check the status of a health setup and proper occupational health measures.

Risk Assessment helps in effective prevention of the spread. It checks the need of improvement in the strategies to adopt Administrative, Environmental and Respiratory Protection Control required for a health care settings.

TB Screening According To Risk Assessment:

Risk Assessment classifies screening into three groups:

  1. Low Risk Setup : Conduct a baseline screening test when hiring the individual. In such setup, annual screening is not necessary.
  • Medium Risk Setup : Conduct a baseline screening test when hiring the health professional . After baseline screening, the individuals need to be assessed annually by symptom screening or test for M. tuberculosis. Individuals with a baseline positive M. tuberculosis infection should receive one chest radiograph result to exclude TB disease.
  • Screening for Health-Care Workers or settings classified as Potential Ongoing Transmission: Testing is performed in a gap of 8 to 10 weeks until the infection transmission seems to be under control and there is no apparent ongoing transmission in the setting.


The Potential Ongoing Transmission stage should be treated with urgency and prompt investigation and preventive measures should be taken. It is used as a secondary classification. Even when the disease is under control and no apparent transmission is seen, the hospital setting should be treated as Medium Risk for one year.

In classification of Low and Medium Risk settings, the setting is classified and treated as Medium Risk setup.


The Essentials of TB Infection Control:

Any health care setting needs a prompt plan of action to control the spread of TB infection through detection, precautions and treatment facilities. The control program is summarized into three categories:

  1. Administrative controls:  It includes management to reduce risk of exposure to TB infected people. Administrative control measures include :conduction of a TB risk assessment of a setting, educating the health care workers on aspects like prevention and treatment of TB infection, use of epidemiological study methods for prevention, screening and testing of health care workers who are at a risk of infection, effective work practices for the management of patients.
  2. Environmental controls: The transmission of TB infection is usually through droplets of the infected person. In order to prevent transmission, reduction of infectious droplet is important. The use of general ventilation and HEPA ( High Efficiency Particulate Air) helps decrease the contaminated droplet concentration in air.
  3. Respiratory-Protection controls: The Administrative and Environmental approach deal with minimizing the exposure of the patient to the infection. Respiratory Protection control is used in situations of high exposure areas, like in Health care workers. In this control, training Health care workers on respiratory protection is done and respiratory hygiene is taught.
