This invention relates to a method of diagnosing tuberculosis by making use of electrical impedance spectroscopy. It relates in particular, to a method of diagnosing tuberculosis by using a novel biomarker presentation vehicle comprising a nanoparticle having isolated mycolic acid of tuberculous mycobacterial origin and activating a screen-printed electrode and thereby immobilising mycolic acid antigen biomarkers on the activated electrode for testing patient samples in the diagnostic assay.
