The development of this rapid and unique test for detection of tuberculosis is considered to be a significant implication in medical history. This test despite of being effective and simple is found to be affordable. The researchers are awaiting FDA
(prHWY.com) June 7, 2012 - Fontana, CA -- 7 June 2012, USA(Kamagrarx.co): A breakthrough research finding in clinical science lead to the invention of a new technique that has the potential to show the results of TB in a fast and reliable way along with being affordable as compared to the current available tests employed for detection of tuberculosis, a detrimental health condition.
The invention of a micro-fluid chip for detecting latent TB was carried out by a team of biomedical engineers with conducting analysis of blood samples of TB patients from U.S and China. Ying Liu, a research specialist said that the biochemical assay developed by them was reusable, cheap and provides accurate results within less span of time.
Tuberculosis is found to have infected around one-third of the overall world population with killing almost 1.5 million individuals per year all over the world, as per a recent statistical results obtained from CDC (Center for Disease Control and Prevention).
Most of the individuals afflicted with this detrimental disease condition observe a latent form of TB with the patient's generally falling sick due to the compromise of their defense system thereby making the bacteria active. The currently accessible tests for determining tuberculosis are based on detection of interferon gamma, a cytokine produced by immune cells to fight against the disease.
Whereas, the researchers coated short segments of the single stranded DNA molecule on a gold wafer that had a specific affinity for interferon-gamma molecules in the blood. Later they introduced the coated wafer into a chip which had small channels for blood samples.
Hence, if the sample has interferon-gamma it would automatically get attracted to the DNA, initiating a chemical signal, which can be detected by the clinician. The process of integration of the micro-fluid sensor and electronic output onto a single chip is on its way to development.
