I'm really worried about my syphilis tests. About two months ago, my TPHA level was 1320 and RPR was 12. My doctor put me on doxycycline, 100 mg twice a day for 21 days. After finishing the treatment, I tested again and my TPHA had increased to 1640, with the RPR still at 12. They then gave me a penicillin injection, 2.4 mu, and told me to get tested after another two weeks. This time, my results were TPHA 1640 again, but RPR went up to 14. I even did a test at a different lab and the TPHA was 12560 there. I'm scared and not sure what's going on. Can you help me understand these results?

Your test results indicate a persistent syphilis infection, and the treatment outcomes are concerning; the increasing RPR titers (1:2 to 1:4) and varying TPHA results (1:320 to 1:640 to 1:2560) suggest that the infection may not be responding to the treatments administered; consult a specialist,

Question

I'm really concerned about something. So, my mom developed this boil on her neck about six months back, and apart from that, she didnt have any other symptoms. We decided to consult a doctor, who suggested a Mantoux test. But heres the thingthe lab technician seemed really new and injected the liquid deep inside her hand, not just under the top layer of skin. After three days, it turned red. The doctor then recommended TB treatment based on the result, even though she wasn't showing any other TB symptoms. With the lockdown kicking in, we couldn't start the treatment for three months. When things opened up, we went back to the doctor, and they suggested another Mantoux test since quite some time had passed. This time, at a different lab, the technician did it right on the outer layer, and it came back negative. Thankfully, the doctor said we didnt need to start any treatment. This whole experience has been pretty confusing, and I'm not sure what to think now. Can a Mantoux test be inaccurate sometimes, or could this have been a mistake due to the technique used?

I'm feeling really anxious about something that happened yesterday. After work, I got a haircut and ended up with some small razor cuts on my head. This morning, my friend who has HIV and had a wet, moist wound on his palm touched the same area on my head where those cuts are. I'm really concerned about whether there's any risk of contracting HIV from this. Could you help me understand if I should be worried?

Question

I'm really worried about how long HIV can live outside the body. Like, if someone with HIV accidentally gets a drop of blood on a chair or table, is it still dangerous if I touch that same spot after 30 minutes? Can the virus still be active?
