Researchers developed a test using a special antibody (TG11) that can specifically identify dangerous mold infections (mucormycosis) in tissue samples. The antibody glows when it finds the molds at early stages of growth, even when they first start germinating. Unlike other diagnostic methods, this antibody can tell the difference between dangerous Mucorales molds and other common molds like Aspergillus, which is important for doctors to give the right treatment quickly.
