A device for rapid detection of a tuberculosis lipoarabinomannan (TB-LAM) is provided. The device includes a pre-concentrator unit for concentrating the TB-LAM comprising: an ion-exchange medium comprising one or more ligands configured to capture the TB-LAM from the source biological sample, wherein the captured-TB-LAM is eluted from the ion-exchange medium as an eluate comprising a concentrated form of TB-LAM; a cassette; a lateral flow assay unit disposed in the cassette; and an integration unit attached to the pre-concentrator unit and the cassette. The integration unit is configured to operatively couple and de-couple the pre-concentrator unit and the cassette. The pre-concentrator unit and the lateral flow assay unit disposed in the cassette are in a fluidic communication in a coupled form. The device for rapid detection of TB-LAM further comprises a dilutor unit.
