While a 4th generation HIV Duo test from Better2Know can detect an HIV infection from 28 days after exposure, it is not considered conclusive at 31 days. Here's why:
- Window Period: The time it takes for the test to detect HIV after exposure is called the window period. While a duo test is more sensitive than older tests, it still takes some time for the body to develop detectable levels of antibodies and p24 antigen.
- Accuracy at 31 Days: While the Better2Know Duo test claims 99.8% accuracy at 28 days, this accuracy increases to 99.9% only after 90 days. This slight difference in accuracy signifies that there's a small chance of a false negative result at 31 days.
Therefore, even though your test result might be negative at 31 days, it's not considered conclusive. Here's what you should do:
- Wait: The recommended window period for a conclusive HIV test is 90 days from the last potential exposure.
- Retest at 90 days: This ensures the highest accuracy and a definitive result.
- Seek consultation: Discuss your concerns and testing options with a healthcare professional. They can provide personalized advice based on your specific situation and exposure risk.
Remember, early diagnosis and treatment of HIV are crucial for managing the infection effectively. While waiting for the conclusive test, practice safe sex to prevent further transmission if applicable.
