Iran, France to manufacture TB case finding kit

Tehran, June 15, IRNA -- Pulmonary and extra-pulmonary TB case finding test kit is to be manufactured by Iran's Pasteur Institute and the French company, Anda, it was announced in Tehran on Monday.

The test which has been found out by the Iranian researchers, for the first time in the world, diagnoses TB mycobacteria within 1-2 hours.

The Anda-TB antigen test detects mycobacteria in a qualitative way in sputum, serum, pleural fluid, urine and etc. The test is performed in about 40 minutes at room temperature. No additional material reagents than those provided with the kit are needed.

The test is based on the collection and concentration of the pathogenic entities present in the sample under analysis, on the surface of a membrane placed on top of adsorbing pads. About 100 microliters of body fluids (pleural fluid, etc) and no more than 50 microliters of serum are processed through the membrane, which retains the mycobacteria on its surface.

The bacteria possibly retained on the surface of the membrane are labelled with antibodies against TB. After a wash, the antibodies present on the surface of the membrane are visualized with gold-labelled anti-rabbit gamma-globulins.

Meanwhile, Dr Ahmad-Reza Barzegar, Head of pulmonary and TB section of Iran's Pasteur Institute told IRNA that fastness and high amount of accuracy are two major characteristics of the new method.

The new method neither needs medical experts nor laboratory facilities for diagnosis, he said, adding that the test can be taken place anywhere.

The TB case finding test has received manufacture license by ISO 9001 and ISO 2002, he added.

According to an accord signed by Iran's Pasteur Institute and the French Anda Company, the Islamic Republic of Iran is to manufacture the kit for 26 world countries. The French company is to manufacture the kit for the European states, Dr Barzegar added.
