I'm really worried about the accuracy of the HIV DUO test, specifically the 4th generation test. Is it really reliable if taken 28 days after exposure? I'm struggling with anxiety over this, and I just need some clarity. Can you help me understand how accurate these results might be?

HIV DUO Test (4th generation test) is highly accurate and reliable after 28 days of exposure. It can detect both HIV antigens and antibodies, providing accurate results earlier than previous generation tests. It is recommended to repeat the test after 3 months for confirmation.

Hey, I had a question about Rabipur injections. So basically, I got 5 shots of it around 14 years ago. I'm wondering if I need to get a booster dose now, and if it's something that lasts for life. Also, how many doses are we usually supposed to get anyway? Appreciate any advice!

It provides immunity for 10yrs.But if you have doubts of exposure to dogs,then getting a booster is no harm.

I'm really confused and worried because it's been two years and my HIV tests are still negative, but I'm experiencing symptoms like nail lines, oral thrush, itchy and painful lips and tongue, swollen lymph nodes in my neck, and a burning and numb sensation in my legs and hands. Could I be a late seroconverter even though my results are negative? What should I do when my symptoms don't match the test results?

You should test for HIV viral load, and CD4 count.

I got bitten by a rat at work about 27 days ago and accidentally scratched the wound too. I did wash it with water right away. My tetanus shot is up-to-date, but I never got any antirabies shots. Now the wound's healed completely. Do I need to do anything more about this?
