  • Method for detecting the presence of mycobacterial material in a sample using at least two antigens
    Patent number: 11243204
    Abstract: Disclosed is a method of detecting the presence of antibodies against mycobacterial material in a sample by detecting binding of antibodies in said sample to at least two types of immobilised antigen, which antigens are capable of binding to an antibody which is indicative for the presence of mycobacterial material in a human or animal. Also disclosed is a solid substrate including a combination of said at least two antigens immobilised to said substrate, and to a biosensor having at least two types of immobilised antigen, which antigens are capable of binding to an antibody which is indicative for the presence of mycobacterial material in a human or animal.
