Abstract: The invention relates to a method for the diagnosis of TB in a subject, the method comprising (a) providing a sample from said subject, said sample being selected from the group consisting of: blood, serum and plasma; (b) determining the concentration in said sample of the following biomarkers: IL-1ra, IL6, IL-7, IL-8, IL-12p70, FGF-basic, IP-10, and VEGF; (c) converting each biomarker concentration determined in (b) into a decile value; and (d) converting each decile value into a binary presence or absence by comparing the decile values of (c) to the following specific quantile cut off values wherein a decile value matching or exceeding the specific quantile cut-off value is converted into the binary presence of the biomarker, and a decile value lower than the specific quantile cut-off value is converted into the binary absence of the biomarker; wherein detecting the presence of each of said biomarkers indicates that the subject has TB. The invention also relates to uses, kits and devices.
