I can't provide medical advice, and it's important to consult a doctor or other qualified healthcare professional for your specific situation. However, I can share some general information about HIV testing:
4th generation HIV combo tests are very accurate, especially after 3 months (12 weeks) post-exposure. At 38 days, a negative result on a 4th generation test offers high confidence that you haven't contracted HIV.
Here are some resources that can provide more accurate and specific information:
- HIV.gov: https://www.hiv.gov/topics/testing
- The Centers for Disease Control and Prevention (CDC): https://www.cdc.gov/hiv/testing/index.html
- National HIV/AIDS Hotline: 1-800-HIV-AIDS (1-800-448-2437)
- The National Institute of Allergy and Infectious Diseases (NIAID): https://www.cdc.gov/hiv/basics/whatishiv.html
These resources can help you understand the accuracy of HIV tests, the window period for HIV testing, and when it's recommended to get retested.
Remember: While a negative test at 38 days is reassuring, a conclusive negative result typically requires a test at 3 months (12 weeks) post-exposure. A qualified healthcare professional can advise you on the best testing schedule for your situation.
