The use of commercial blood tests to diagnose tuberculosis or TB, does more harm than good.

After a year long study, theWorld Health Organization (WHO) has called for an immediate halt to the use of blood test kits for detection of TB.

WHO says the test kits are produced by Western companies, but exported to developing countries because they do not pass regulatory standards in developed nations.

Dr. Mario Raviglione is the Director of the WHO Stop TB Department.

"These blood serological tests are inaccurate and lead to misdiagnosis and mistreatment potentially of patients. They are a waste of time and a waste of money and very importantly, they put at risk those people that suffer from tuberculosis."

WHO says, alternative tests should be used.
