I'm really worried after visiting a barber shop because I'm afraid I might have been exposed to infections like HBV, HCV, or HIV. Could you tell me more about when I should get tested? I heard that an antibodies test for HIV can be done after 4 weeks or even up to 12 weeks, but I also read something about a p24 antigen test that can be taken after 4 weeks. How accurate are these tests? I could really use some advice right now.

Antibodies test for HIV can be performed after 4 weeks for preliminary results, but for more accurate results, it is recommended to wait for 12 weeks post-exposure. The p24 antigen test can be performed after 4 weeks to detect the HIV virus directly. It is important to follow up with healthcare provider for further evaluation and management.

I recently found out that my girlfriend had a past relationship, and now I'm just a bit anxious about things. To be cautious, I decided to get tested for HIV 1 and 2 using the Elisa method, and my results came back with a value of 0.09. I've attached my test report here. Could you help me understand what this means? Should I be worried or take any further steps?

-Hello, It's understandable that you're concerned. A result of 0.09 from the HIV 1 and 2 ELISA test is typically considered negative, as it is well below the cutoff for positivity. However, it's always a good idea to follow up with a healthcare profes

I recently did a Dengue test, and my Dengue IGM came back positive, but the Ns1 Antigen and IgG were negative. What does this mean for my health, and what should be my next steps? Should I be concerned?

Since your Dengue IgM test is positive, it indicates a recent infection with the Dengue virus. It is important to stay hydrated and get plenty of rest. You can take Paracetamol 500mg every 6 hours as needed for fever and body aches. Additionally, you should monitor your platelet count regularly and seek medical attention if you experience any warning signs such as persistent vomiting, severe abdominal pain, or bleeding.
