Blood test for TB detection

Italian scientists have discovered a new way of testing blood for latent signs of tuberculosis is more effective than traditional skin testing.

Staph (Clostridium) - one of the potential bacteria of tuberculosis. The group of scientists at the University of Modena and Reggio Emilia, Italy analyzed the skin samples of an infected person but gave inaccurate results. Two blood tests give more accurate results.

With this blood test method, doctors will help early detection of those with TB germs but have not developed into the respiratory tract, so there will be timely treatment to destroy the root of the pathogen.

Tuberculosis is a disease that easily spreads germs or rod bacteria to other people through coughing, sneezing, talking and spitting. The most vulnerable group of tuberculosis is newborns, children, the elderly, people living with HIV-infected patients and drug addicts.

According to the statistics of the organization, every year 9 million people worldwide suffer from tuberculosis and 2 million people die from the disease. The World Health Organization warns that the number of people suffering from this disease has reached alarming levels in Africa, where the transmission of tuberculosis is associated with HIV.

In addition, half of the people with tuberculosis are left in Bangladesh, China, India, Indonesia and Pakistan.

Dr. Luca Richeldi, lead researcher for Lancet Medical Journal reporters, said: "In order to control and limit tuberculosis in areas where there has not been much infection, the precise and sensitive testing method is very necessary".

Therefore, using a blood test can be combined with a skin test or a replacement skin test to detect the potential signs of TB germ early. But the choice of test method depends on the number of infected people, the purpose and the medical conditions available.
