The Tri-Dot test is a rapid HIV antibody test that is very accurate and sensitive at detecting HIV infection. Getting a negative result means that you are HIV-negative.
If you have been potentially exposed to HIV over the 3 months before taking the test – I don’t think this is the case because you have been using condoms – then you could confirm this with another test in three months.
Your girlfriend will now need to have other blood tests including a CD4 test to check whether HIV has damaged her immune system and whether she needs to start treatment, and a viral load test if this is available in your country. She should also see a doctor about the ulcer.
You do not need to take any prophylaxis treatment for your own health, but you will need to make sure you continue to use a condom during sex.
The following link show results that show that the TriDot test has over 99.9% reliability.
