The One Step TB (Mycobacterium Tuberculosis) Test is a rapid, serological, immuno-chromatographic assay for the detection of antibodies for Mycobacterium Tuberculosis (TB) antigen in human serum or plasma. The test is used to obtain a visual, qualitative result and is intend for healthcare professional use.
TB(Mycobacterium Tuberculosis) Test uses a double antigens “sandwich principle” for the detection of Tuberculosis antibody in human serum.
Two recombinant Tuberculosis antigens (TB Ag 1&2) were mixed and immobilized on the test band region, and an antibody to Tuberculosis on the control band region of nitrocellulose membrane. Another Tuberculosis antigen (TB Ag 3), coupled with colloidal gold particles is dried on a conjugate pad. During the assay, the specimen is allowed to react with the colored conjugate (antigen-colloid gold conjugate); the mixture then migrates chromatographically along the membrane by capillary action. If the specimen contains Tuberculosis antibody, the recombinant antigen immobilized on the membrane will capture the antibody –antigen-colloidal gold complex and form a colored test band on the membrane indicating a positive result. Absence of the test band suggests a negative result. To serve as a procedural control, a colored band at control region always appears in the test area.
