TB ELISA kits are assays designed to measure levels of TB-associated antigens in biological samples, such as plasma, serum, culture extracts, and cell lysates. TB may refer to antigens directly associated with tuberculosis infection, such as bacterial proteins or tuberculosis-reactive immunoglobulins. TB may also refer to total bilirubin protein, a biomarker for liver health. Tuberculosis infection is caused by Mycobacterium tuberculosis colonization in the lungs. TB ELISA kits utilize microtiter plates coated with specific antibodies and conjugated detection enzymes. The assay will produce a detectable signal proportional to the amount of TB antigens found in the sample.
