A method of diagnosing tuberculosis (TB) disease and distinguishing between active TB and latent TB infection in a subject is described herein. A sample from the subject is stimulated with at least one() infection phase-dependent antigen selected from Rv0081, Rv2032, Rv1737c, Rv2389c, Rv0867c, TB18.2, Rv2099c, Rv1733c,PPD, PHA and ESAT-6/CFP-10 and the presence of at least one host marker in the sample is detected, the host marker being selected from EGF, TGF-&#x3b1;, TNF-&#x3b1;, VEGF, RANTES, IL-12(p40), IL-12(p70), IL-10, IP-10, IFN-&#x3b1;2, fractalkine, IFN-&#x3b3;, IL-13, IL-1Ra, IL-3, IL-4, IL-5, MIP-1&#x3b1;, ENA-78, BCA-1, TARC, X6-Ckine, eotaxin, eotaxin-2, SCF, APOA-1, APOE, HPALBN, HCF, Serum amyloid protein A (SAA), C-reactive protein (CRP), serum amyloid protein P (SAP), TIMP-1, MIP-1&#x3b2;, IL-6, GM-CSF, IL-1&#x3b1;, MMP-9, MMP-2, MCP-1, TRAIL, IL-15, IL-17F, IL-22, TNF-&#x3b2;, MCP-2 and MCP-4. Additional host markers may also be detected in an unstimulated sample from the subject.
