The blood test for tuberculosis is known as the IGRAs (interferon gamma release assays) And will measure what your response is to TB antigens, which will measure the response to TB and trigger the manufacture of antibodies. The test conducted at Blood London is the Quantiferone TB Test. When your blood test is being done you will not need to see the doctor again If the result is negative or if you have been given the BCG vaccine. However, if your blood test reveals that you have been infected with TB, you will be tested further to find out whether the disease is latent or active.
A bacterium called Mycobacterium tuberculosis is responsible for tuberculosis. If a person has active TB and they sneeze or cough, if someone else inhales the droplets that have been expelled containing the TB bacteria, they will be at high risk of developing this disease.
Generally TB will make somebody feel weak, sick, experience night sweats and fever as well as weight loss. Where TB is in the lungs there might also be chest pain coughing and blood in the sputum.
