I had thrombocytopenia from rifampin
It is possible to get a blood test to show drug dependent antibodies through Versiti labs
If present , it is dangerous to use rifampin ever again as drop in platelets can be rapid and severe. The test needs to be done quickly after stopping rifampin to avoid missing the antibodies

My dr. Did not suggest that at the time but did order at least 15 labs. All came back “normal and a hematologist reviewed all. My platelets popped back to normal after 2 weeks off rifampin. So consensus was to not go back to rifampin. I will discuss that antibody lab when I see my ID doc in late may. She wants another platelet count in 2 weeks to see where they land. After starting back on azithromycin and ethambutol.
