The present invention relates to a method of detecting an active tuberculosis infection in a serum sample from an individual. More specifically, the disclosed method uses a single chain variable fragment from a monoclonal immunoglobulin specific for mycolic acids of mycobacterial origin to detect surrogate markers, the presence of which indicate the individual has an active tuberculosis infection. Markers useful for practicing the disclosed method can be serum mycolic acid antigen, serum anti-mycolic acid antibodies or both. In a preferred embodiment, the method is practiced using a lateral flow assay format.
