FTA stands for?

Explanation:
FTA is a test that detects antibodies against Treponema pallidum, the bacterium that causes syphilis, using a fluorescent label to visualize those antibodies. The name reflects that it’s a fluorescent antibody test targeting treponemal antibodies, which is why the correct expansion is Fluorescent Treponemal antibody. This distinguishes it from tests that look for antigens or for antibodies to other organisms. The other options describe unrelated targets (antigen, Toxoplasma, thyroid antibodies), so they don’t fit what this test measures.
